Not bad. A couple tips (I've done thousands of these, and I have an excellent success rate): 1) when you first cut away the jacket, depending on your cutting tool there is always a theoretical risk of accidentally scoring one of the conductors inside the cable. When you score a copper wire laterally, it can then easily break just by bending it a few times, which will happen over the life of the cable. The string you see alongside the conductors is a strength member. Use it to rip away more of the jacket. Pull on it to tear through the jack back a few more inches and then cut away the outer jacket with your snips (diagonals). Now you're starting with a safe section of wire. Then start the process of untwisting your pairs and aligning the individual conductors. 2) pairs should never be untwisted more than 1". The more you untwist the wires, the more you invite the chance of Near End Crosstalk noise into the cable. 3) if you find you're having a problem getting the outer jacket of the cable into the housing of the RJ45 plug, usually because you've cut the conductors too long, then either trim the conductors accordingly, but then sometimes the problem is the twists get too close to the connector making it difficult to dress the conductors into the plug, then try this: Before you put the conductors into the RJ45 plug, hold the conductors laid out in one hand, and then while trapping the cable under your foot about 5 or 6 feet back from the end, then grip the jacket with your free hand and slide your hand over the cable like you're squeezing toothpaste out of the tube. You will see the outer jacket creep up the conductors at the end as if the jacket is being stretched. This is a great way to get a little more jacket to cover the last twists. Then cut the excess of the conductors and dress into the RJ45 plug. 4) Make sure you visually see the copper centers of all 8 conductors shining through the end of the plug when you dress the conductors into the plug. The conductors you don't see are not in far enough. 5) Once I have the cable dressed into the RJ45 plug, I never let go of it until after it's been crimped. As you are crimping the plug apply some positive pressure to the cable to make sure the conductors remain fully seated during the crimping. Hope this helps
For inhouse wiring, I would suggest first laying the whole cable, then adding the RJ45 connectors, it makes it easier to get the cable trough pipes/holes in my experience.
Thx Linus from 6 years ago! I bought a 250ft spool of cable for $25 bucks and an entire crimping kit for another $25! Now my networking solution is litty!

White/Orange Orange White/Green Blue White/Blue Green White/Brown Brown And yes, I had to listen to it 3 times on half speed...a bit of a fail indeed. I still don't know if that's right to left or left to right starting with White/Orange.
I’m glad this is not the first video I check out from this channel. I was first watching the tutorial from Tek Syndicate”How to make RJ45 Network Patch Cables - Cat5e and Cat6” great tutorial on how to ACTUALLY crimp and aligning the patterns in different angels plus a diagram on the left for a million times. If you guys wondering wtf is this guy talking about you need to check that out and with non technical terms even I can do it myself for the first time after watching the video. But I still have some questions about how do I determine what cables I need and the actual differences between the two on internet speed etc, so I came across the video “Cat5 VS Cat 6 - what’s the differences” from this same channel. The speaker had mentioned to check this video out if I wanted to crimp my own cable so I was like why not let’s browse around since he gives out a great informative video and on point explaination. I hit the subscribe button the moment he finished but after this video I wanted to unsubscribe already. Bro if you don’t wanna give out educational tutorial and feels like everybody knows how to already, don’t even bother to record this video. It’s wasting your time and our time :) in the future I think it will be better off pretending that everyone is a newbie and non tech person and explain every little stuff, provide diagrams, closer angle on what you do (the product, not you), non tech terms, informative with a bit of humor but not the whole 6minute trying to be funny. you are probably cute and outgoing personality but no I don’t need you to feel beautiful or dance out in front of the camera, Not a dance tutorial 🤭
I'm opening up a VR business and was looking into cat5e wires and... stumbled across making my own. I do wiring for electrical and use crimps for plumbing... this is so straightforward im frustrated i never tried it before. Thanks for the video!
Get the RJ45 connectors where the twisted pairs (or untwisted pairs when you stick them in) go all the way through and out the other side. It makes the job so much easier than having to worry if your twisted pairs are all cut exactly the same length.
I always found making Ethernet cables a nightmare these are the types of video i want to see some things that might seem basic but are incredibly useful
I just needed to run a few cables so I've done mine w/o the tool just a small screwdriver to push the tabs in. The guy running wire to the house had a bunch of loose wire which he gave to me. Literally enough to run across the attic from one end of the house to the other and I still have a hundred feet or so. Be nice to the cable guy!
I DO THIS DAILY. SO WORTH THE INVESTMENT FOR A GOOD CRIMPER NEVER BUY PRE-MADE CABLES AGAIN SOOOO WORTH IT. BUT THANKS LINUS, ALWAYS GOOD TO HEAR YOU COVER SOMETHING. (damn caps oh well)
I remember learning it not that long ago in technical high school. Our teacher taught us how to do it in a very clever way, so we could learn the procedure better. Basically you follow Linus' steps until it comes to realigning the wires. Realigning, because we also learned how to make a crossover cable. He got us a torn apart old telephone socket and a little split screwdriver. We pushed the wires in between the contacts inside of that box with that screwdriver and the socket was connected to an ethernet tester on both sides. If the pairs were twisted correctly, the diodes on the tester would blink. And then it was just the matter of taking out all of those wires and shoving them as they were into the RJ45 plug and crimping. Not like you're gonna do it that way till the end of your life, but it's easier for noobs, I guess. The hardest part is actually putting the wires into the plug, you're going to need some surgeon precision and shit. And patience. I'm pretty sure that that particular step wasn't shown in the video, because it took Linus 5 hours.
Check your local electronics/Satellite tv shop. I found a 2 part blank plugs there, 1st part is a small piece of plastic that you thread the twisted pairs through, trim the wire at the end of the insert and plug into the main body of the plug. For those like myself who can never manage to cut the wires to the right length or keep them in order.
Cat 5e cables are a breeze to make, compared to Cat 6 cables! Those little separators that offset the wires up and down for the Cat 6 connectors are a major PITA, and the Cat 6 spline doesn't help when you're trying to cram the separator down far enough in order to have the connector grab the cable jacket. I was hoping Linus was going to explain how to do Cat 6 connections with less frustration, but I guess there's no such thing!
actually I managed to buy perfectly length cables I guessed all of them and managed to buy them just long enough. lucky as hell that I didn't buy them too short. I thought I had over estimated but I hadn't. But it was just cheaper for me to buy premade because all I needed was 2 cables 1 10f and 1 15f which only costed me like £10~
Is there any tricks and techniques to be faster at crimping Ethernet cables? The school is planning on a tournament on who's the fastest crimper of the year.
I make cat 5e cables a lot at work. after a while it just comes natural making these cables. imagine making these cables and running them over 60 feet in the dark. lol. true story. fun times.
funny how we skipped the hardest part...sliding the pairs and make sure they got slid into the right order of slots....unless you have a push through rj45
The ends I use have little sleds you put the wires through before you cut them to length. then you slide the sled to the end of the wires and put it in the connector. it makes it really easy
They also have some that you just push the wires all the way out of the connector. Then when you terminate it the wire will be cut

U should also mention that this is B setup ( most common) and it's recomended les than 100m for optimal use if u will have more than 100m advanced cable testers will fail the test. but it still gona work!
I have been squeezing my crimper so hard that the gold pin on the connector doesn't make contact with the pins on the socket. I told me a whole year to figure out why. Thanks Linus
Can you help me? I have HDMI type CL3 cables run in the walls. I didn't install any rj45 wires. Now I need to install a router in the basement where only have HDMI and coaxial cables. Is there a way to connect a second router using one of these wires? Thx
You can get connectors and wire cheap from Ebay and Amazon, just look around. A lot of the listings on Ebay are from China so it can take a bit longer to ship but for about the same price for 50 connectors at retail, you can get 500. Also, you can use CCA(copper clad aluminum) wire instead of solid copper for most runs and be fine, especially if just doing stuff around the house.
Good Tutorial ....Thanks. However I have got some Flat Cat6 cable and I want to crimp that and I'm struggling with that. Can you please do a video on that. Thanks.
On testing the cable, you can use two Raspberry Pi's (for 10/100) or CubieBoard 8's (for gigabit) and let the software to tell you if the Ethernet connection is established properly (one LED on the GPIO pin is enough)
yes and no... the signal goes in an inverted polarization over a twisted pair, so the the magnectic fields cancel each other... If you keep the pairs as it goes it shouldnt have any problem with performance If you don't keep the pairs, you could end with some crosstalk, that could reduce the maximum lenght of your cable. for small lengths probably wont do any harm. There's also the fact that this is a standadization, so anyone can understand your cabling and it is easier to troubleshoot problems... (sorry for any missused term, english is not my native language)
Guilherme Freire The purpose of differential pairs is not to cancel out the magnetic fields, but to reduce interference. The information is carried by the difference between the lines and because the lines are close to each other, or in case of the cable twisted, the interference signal affects both lines in almost the same way. The signal is sent with opposite polarity on the two lines. On the receiver end the negative one (usually) gets inverted so both signals are the same polarity but the interference signal is now of opposite polarity. The signals are then added, with the effect of doubling the level of the wanted signal and removing the interference.
the string is for striping the jacket back. don't trust the stripers. they'll nick the pairs. You'll get shorts or crosses. use the striper grab the string and pull back to strip the sheath then cut off the excess and put your end on.
No it's not. It's a messenger for pulling the conductors through the outer jacket during manufacture but hey you can use it for that if you wish to distort the fuck outta the conductors in the cable. What you do is use the strip tool to SCORE the jacket then you bend it until it separates. Linus is so f'ing incompetent he didn't even manage to get the conductors to the end of the 8p8c connector and if you look in the video at 4:57 you can see only one of the two prongs actually hit the UTP strand! Totally incompetent yet he's arrogant enough to come on here thinking he knows how to crimp properly. JOKE
If you are really paying close attention Linus is not the person who is crimping this cable. All he did was voice over while someone else did the crimping (which person has much fatter fingers than his wearing a sweatshirt and not a tee shirt that he has on and wearing different watches)
I got a 100ft Ethernet cable for $8 from work at 5% over cost, So 1000ft at $100 is actually an awesome deal considering that 100ft retails for around $70-80
Will you mail me my geek badge? I have made lots and lots of RJ45 cables for countless customers. And how did I like doing this? I HATED IT WITH A PASSION!
I did this in my networking class in high school and it was a pain in my ass. For the life of me I wasn't able to get the cables inside the plastic in the right order. I had it in the right order before it went into the plastic but once it went inside it got completely out of order.
Good falsetto! Made me smile! I appartently bought a Farady cage house. So by by wireless and hello faster, cabled connections. Might be cheaper making my own, certainly can control length. What about new docsis 3.1, will cat 6 handle that?
That's just the cabling pattern? That's a relief. I looked in to some diagram way back, and it was confusing as hell. The first end was Orange with Stripe, Orange, Green with stripe, blue, blue with stripe, green, brown with stripe and brown. At the other end was a whole lot cluster fck that's so very different with the first one.
it doesnt matter if you make both ends the same tho. Unless you want a cable that does crossover, but routers do that themselves these days. Just do it with solid and striped of the same color next to each other to not have performance issues.
Richard Smith Each pair has a different amount of twists on it so that different pairs don't crosstalk, and data is sent as differential signals over twisted pairs - mixing wires is a bad idea. - you CAN get away with just any old colour matched on both sides for slow speeds and short distances, but once you get gigabit across your house, you want the correct pairs or you'll start getting a lot of errors that are hard to diagnose when the fridge turns on or lightning strikes.
one question i havea 25m ethernet cable that my cat bit and cut it, can i buy the plastic little thingy and just make a new cable from the cut? WILL IT HAVE the same performance? even if its nanoseconds of delay will it be slower? i JUST want to know the truth.
Do the colors have to be in a specific order when they go in. Like say red, blue, green (THIS IS AN EXAMPLE) like it was placed in the video but say I do something like green, red, blue. Will it still work?
I bought a kit and ethernet, tried it out.. and yea. I think I am just going to buy mine pre-made. Not worth the effort for normal runs IMO. Will keep it for wall fishing and long runs.
I do this for a living.. It depends in what country your live in.. Mainly in the U.S we use the A side color code which is the one Linus did.. But in some cases the A side is used.. It also depends on what cable your using, cat 5e is the quickest one.. Cat 6a uses a slight different rj45 with 2 extra steps but overall the same concept
I've bought a 30m terminated length of flat cable, but I want to shorten it. I have the tool and rj45's, but the cable grip won't catch the flat cable. I've googled for a solution, but found nothing, can you help?
my entire network is set up with custom cat6 cables also cat6 is way harder to work with than cat5e since the devider in the middle is in the way when putting the pairs in order also the thicker wires makes it harder and that the devider is sometimes in the way when crimping and then the plastic bit pops out when done
Pro tip: Instead of cutting straight, cut diagonal so you can put one cable in its channel at one time instead of trying to get them all in at one time.
Does the length of the cable affect speeds? For example, if I were to use a 1000ft cable to connect to my neighbour down the road's internet. Would it be SLOWER than if I were to buy my own internet and use a 2 ft cable, within my own house
yes it does, on every cable there is written a number, a lot of them numbers, for eg. 100 meters (< what is this meter yeah?) there is a specific loss of speed, there are different cables for different purposes, and different costs as well
Can you do a video crimping some CAT6 shielded with that annoying cross thing in the middle? I have no frikin idea how you are supposed to terminate that without making a massive mess lol
I would have gotten in so much shit when I worked for at&t for stripping a cable the way you did. Yes you can use that tool to strip the sleeve off but you must pull the nylon thread to split the sleeve further back and cut off where you did the first strip. Of course you wont get a short from that first strip but you will open the pairs up to the air/moisture. that style of stripping tool almost always cut the insulation on the pairs. All it takes is moving the wires just a little bit to open the cut the rest of the way to where the copper is showing. This is coming from an engineer at a wiring harness manufacturing plant. We make harnesses for Caterpillar and EMD. If we did cut a cable or wire we have to put glue lined heat-shrink over the area. Even then most of the time we had to trash the entire cable because most cables we were not allowed to repair in that fashion. I love you videos Linus but if you are going to show people how to do something show it the right way.
Which tool are you referring to? The one shown at 2:50 or the one shown at 3:00 ? I work in a hospital, IT department I'm sure you already assume, and we use this tool (www.fullcompass.com/product/382026.html?gclid=CIG6vdW8kMICFRPItAod4ycAHA). What Linus showed or did in this video is not done wrong or incorrectly. Here at the hospital, and in all of the business's I've freelanced in, we use the method and tools shown here by Linus. What we do not do is make our own male-to-male (or female-to-female) cables. We only terminate our own cable when we're running network drops (running cable from switch to wall mount). The reason we don't make out own male-to-male cables is because they're not as good as the ones made by professionals such as yourself. Cables made in this method can be buggy, can be poorly made, and can fail. Which is why our switches are filled with quality, professionally made, cables that you and your colleague's make. Although you may make wire harnesses instead of Cat5's, but my point is the same.
@3:00 and @2:50 The blade tends to damage the pairs allowing air/moisture inside the strip. I have personally went out on so many service calls I cant even begin to count because moisture has caused a wire to corrode and break or cause a high resistance fault. Indoors the cut wouldn't hurt anything really. But in a wall or attic it can be pretty hazardous. My cat5 cabling comes from working at at&t, doing home networking, and installing security systems. I would not use the blade you linked to for anything more than starting my strip. P personally I would just use my snips to cut into it and pull the thread back. Then I would cut off where I entered the cable. Then the jacket to prepare for the connector. My manager told me that we were flat out not allowed to use that as our finish strip due to the massive amount of issues they were having. real world stats from a massive company that logs every little issue a tech finds on repairs.
Justin Barnett You act like we hack saw the cable. It only takes one rotation to remove the outer tubing. I'm also an engineer, electrical engineer, and the tool I listed and the one from 3:00 are common and recommended. Not so much the method with the crimper Linus showed, cause that tool's a bit barbaric for stripping, but it's still common and not really an issue. If you're worried about the corrosion of the cable, then you've got some butchers at AT&T. For the copper corrosion to be a real concern it would have to be in a very damp place or just tossed into a puddle and left there. Like I said I work in a professional environment, and always have, and that shit don't fly. If an area is so moist that the copper is going to corrode, then the building is probably filled with mold. It's cool that your manager at AT&T is used to having issues from poorly made and/or poorly installed cables, but there is nothing wrong with these tools. If you prefer to not use the tools because you don't want your pairs' insulation compromised, that's cool, but cat5 terminating isn't as difficult as you're saying it is.
Those tools were what was causing the issues. If you nic the insulation on a pair and then work with it it will almost always expose the copper.(really depends on the cable brand and types of insulation used. If it was winter it was almost guaranteed to break.) The tool you posted might be okay to use but the yellow one he used the blade is to deep. At my work when we setup the machines for stripping wires they don't cut through the outer insulation. It just scores it. Then its pulled apart. not cut through at all in any way to ensure nothing could happen. My experience is from 2 fields that are miles apart in terms of how cables are managed and worked with and both companies when it comes to perfection will not cut a cable (not just talking about cat5) using a blade like that. It would only be used to score it. Like I said before it is fine indoors for things that don't matter but I build harnesses and run cables that are meant to last 30+ years. The fact is you work in a nice climate controlled hospital. The stuff I deal with is in trains and heavy equipment. Hell even some of the harnesses I've worked with are in submarines. In areas that have to work no matter what. I guess my high standards are to high for a hospital or the IT field your used to. But for telecom work that's outdoors and in heavy equipment where one harness needing to be replaced would cause a piece of equipment to be completely tore apart and have days of downtime over something that could be so minor as cut insulation from carelessness... You don't have to deal with extreme temp changes. The cable does. When the insulation gets cold it contracts. It will open up any small cuts.
Justin Barnett So wait: "Like I said before it is fine indoors for things that don't matter but I build harnesses and run cables that are meant to last 30+ years. The fact is you work in a nice climate controlled hospital. The stuff I deal with is in trains and heavy equipment. Hell even some of the harnesses I've worked with are in submarines. In areas that have to work no matter what." I would say that Linus's office is probably not in a train or a submarine, nor does it run through any heavy equipment. That's all I've been saying, that Linus is showing how to properly terminate a cat5-6 cable. So since damn near none of Linus's viewers are going to be making ethernet cables for use in submarines, and if they are they probably already know how to do it, that Linus just showed the correct way to terminate an end. Your method may be needed for the much more complex wire harnesses used by Cat and EMD, but that would make your method a special case use.
Actually the color order doesn't matter as long as you do it in the same order on both sides. But if you need to modify the cable later, then it would be better to sue the color order standard(mentioned in the video).
This was a painful process, organizing the cables in the right order was one thing, but keeping them in that order as you insert it into the jack was painful.
I wonder why this video have so "few" views. I mean Linus constantly brings up stories about NCIX and it's not rare him saying that he was a host of the youtube channel.
I like to think I know fairly enough about PC hardware and quite a bit about the software stuff, but I'm just a dud when it comes to networking. My only skill with networking is the windows 7 troubleshoot option, and if that doesn't work, than I just unplug the thing. Oh yeah, and my roll of unnecessary cable is about 5m, but that has to be there, it looks more badass like that :D
One more reason to do it yourself is to save money. I have seen cables in stores ready made but they are so over priced when you think about it. You can get bulk cable cut at most home improvement stores what ever length you want. It will almost always be cheaper than buying them ready made especially when you get to name brand cables. The connectors aren't that expensive either. The only reason I would ever buy one ready made is that I find crimping a crossover cable frustrating. I can do a patch cable easily enough but it will be at my own pace. My problem with crossover is still having the ends of all the wires even when it comes time to crimp the end on. I am sure that I am not the only one who finds that frustrating.
Linus making look easy but my friend I tell you this whole process is pain in an ass. Once you punch wire you will have difficulty for copper to get contact with respective colour wires..I always miss the mark by mm.. It is simply nightmare for me.Tks Linus for sharing this beautiful classic technique.
Linus you forgot to mention something. You have Straight pairs and Twisted pairs. But at least i know you did twisted. You could of mentioned this on the vid.
i work for a Computer Technician and we work at a private school. he has the easy job of crimping them, i have the hard job of running around in the crawlspace and handing him the wire into the right room...
Any tips on dealing with smaller gauge cat5e cable? I've had no issues crimping cables in the past but found it almost impossible to get the (most likely 24AWG) wires to stay in the correct order while placing the connector on, they just aren't rigid enough. My current plan is to get some keystone jacks as a workaround but I'd like to know if there is a better solution. (I cannot just change the cable as it is fixed in a wall)
Its a little plastic sled you put the wires in before you insert them into the connector. So that you don't have to fight and hope they don't get out of order. These are similar to what I have www.monroviamac.com/RJ45-CAT5E-8P8C-Crimp-Connector-for-Stranded-includes-insert-guide-50-pieces-per-bag-Prodview.html
Who is this Linus guy? He’s pretty helpful, he should probably start his own channel.

When you score a copper wire laterally, it can then easily break just by bending it a few times, which will happen over the life of the cable.

2) pairs should never be untwisted more than 1". The more you untwist the wires, the more you invite the chance of Near End Crosstalk noise into the cable.
3) if you find you're having a problem getting the outer jacket of the cable into the housing of the RJ45 plug, usually because you've cut the conductors too long, then either trim the conductors accordingly, but then sometimes the problem is the twists get too close to the connector making it difficult to dress the conductors into the plug, then try this:
Before you put the conductors into the RJ45 plug, hold the conductors laid out in one hand, and then while trapping the cable under your foot about 5 or 6 feet back from the end, then grip the jacket with your free hand and slide your hand over the cable like you're squeezing toothpaste out of the tube. You will see the outer jacket creep up the conductors at the end as if the jacket is being stretched. This is a great way to get a little more jacket to cover the last twists. Then cut the excess of the conductors and dress into the RJ45 plug.
4) Make sure you visually see the copper centers of all 8 conductors shining through the end of the plug when you dress the conductors into the plug. The conductors you don't see are not in far enough.
5) Once I have the cable dressed into the RJ45 plug, I never let go of it until after it's been crimped. As you are crimping the plug apply some positive pressure to the cable to make sure the conductors remain fully seated during the crimping.
Hope this helps
It helps a lot. Specially step 1 was very useful for me
Way too complex for me man I just need someone to do this for like 50 bucks
For inhouse wiring, I would suggest first laying the whole cable, then adding the RJ45 connectors, it makes it easier to get the cable trough pipes/holes in my experience.

"Linus arm spans" should be the official measurement metric for all cabling.
That's how we count line aboard ships. Average arm spans are about 6 feet. 6 feet = 1 fathom.

Or you could check the description. Or Google it.
It really doesn't matter, you just need to match one end with the other, same colors in the same position and you'll be ok.
You didn't put the boot on before you stripped the cable. And didn't mention anything about the difference between T568A and T568B.

Thanks, young Linus. I hope you’re doing good these days.
2:25 That was beautiful.
Get the RJ45 connectors where the twisted pairs (or untwisted pairs when you stick them in) go all the way through and out the other side. It makes the job so much easier than having to worry if your twisted pairs are all cut exactly the same length.
I always found making Ethernet cables a nightmare these are the types of video i want to see some things that might seem basic but are incredibly useful
I just needed to run a few cables so I've done mine w/o the tool just a small screwdriver to push the tabs in. The guy running wire to the house had a bunch of loose wire which he gave to me.

i needed to know this in 2021, stumbled upon this video, even though there are better toturials to do this now, i couldn't resist.
I wonder how many times it took them to get the perfect shot of them inserting the cable into the connector.
I like the connectors that allow the wires to pass through the end which you shave off when done. :)
I DO THIS DAILY. SO WORTH THE INVESTMENT FOR A GOOD CRIMPER NEVER BUY PRE-MADE CABLES AGAIN SOOOO WORTH IT. BUT THANKS LINUS, ALWAYS GOOD TO HEAR YOU COVER SOMETHING. (damn caps oh well)
You have a edit button, but good work not seeing you had caps on before the end of your post and you still posted with big letters, clap clap.
eLoeL it happens to the best of us man
its called effect/ google "comedy"
I remember learning it not that long ago in technical high school. Our teacher taught us how to do it in a very clever way, so we could learn the procedure better. Basically you follow Linus' steps until it comes to realigning the wires. Realigning, because we also learned how to make a crossover cable. He got us a torn apart old telephone socket and a little split screwdriver. We pushed the wires in between the contacts inside of that box with that screwdriver and the socket was connected to an ethernet tester on both sides. If the pairs were twisted correctly, the diodes on the tester would blink. And then it was just the matter of taking out all of those wires and shoving them as they were into the RJ45 plug and crimping. Not like you're gonna do it that way till the end of your life, but it's easier for noobs, I guess. The hardest part is actually putting the wires into the plug, you're going to need some surgeon precision and shit. And patience. I'm pretty sure that that particular step wasn't shown in the video, because it took Linus 5 hours.
I learned how to do this when I was getting my Associates in Network Management.
you hit the spot on this one for me ,this vid is just what i needed =D
Check your local electronics/Satellite tv shop. I found a 2 part blank plugs there, 1st part is a small piece of plastic that you thread the twisted pairs through, trim the wire at the end of the insert and plug into the main body of the plug. For those like myself who can never manage to cut the wires to the right length or keep them in order.
Cat 5e cables are a breeze to make, compared to Cat 6 cables! Those little separators that offset the wires up and down for the Cat 6 connectors are a major PITA, and the Cat 6 spline doesn't help when you're trying to cram the separator down far enough in order to have the connector grab the cable jacket. I was hoping Linus was going to explain how to do Cat 6 connections with less frustration, but I guess there's no such thing!
2:26
Linus should start singing the NCIX intros and outros
Hmm, this video was actually a really good idea and super helpful.
thanks i learned a lot from you man you are a total walking talking big box of tech knowledge :)
That's some nice Linus Tech Tips.. He should start a channel!
actually I managed to buy perfectly length cables I guessed all of them and managed to buy them just long enough. lucky as hell that I didn't buy them too short. I thought I had over estimated but I hadn't.
But it was just cheaper for me to buy premade because all I needed was 2 cables 1 10f and 1 15f which only costed me like £10~
Is there any tricks and techniques to be faster at crimping Ethernet cables? The school is planning on a tournament on who's the fastest crimper of the year.
I make cat 5e cables a lot at work. after a while it just comes natural making these cables. imagine making these cables and running them over 60 feet in the dark. lol. true story. fun times.
funny how we skipped the hardest part...sliding the pairs and make sure they got slid into the right order of slots....unless you have a push through rj45
The ends I use have little sleds you put the wires through before you cut them to length. then you slide the sled to the end of the wires and put it in the connector. it makes it really easy
yeah..i love those...ez-rj45 they call it something..it's a push through so you can confirm the order way easier..then you can trim off the excess
They also have some that you just push the wires all the way out of the connector. Then when you terminate it the wire will be cut
U should also mention that this is B setup ( most common) and it's recomended les than 100m for optimal use if u will have more than 100m advanced cable testers will fail the test. but it still gona work!
This kind of looks like the guy from linus tech tips.
I have been squeezing my crimper so hard that the gold pin on the connector doesn't make contact with the pins on the socket. I told me a whole year to figure out why. Thanks Linus
LOL I am going to need to do this today for a project The timing is awesome although I already know it.
Can you help me? I have HDMI type CL3 cables run in the walls. I didn't install any rj45 wires. Now I need to install a router in the basement where only have HDMI and coaxial cables. Is there a way to connect a second router using one of these wires? Thx
And the correct order is hakdhskshskdhs! Thanks... thanks a lot. Ended up finding a different source that actually helped me on that one.
You can get connectors and wire cheap from Ebay and Amazon, just look around. A lot of the listings on Ebay are from China so it can take a bit longer to ship but for about the same price for 50 connectors at retail, you can get 500. Also, you can use CCA(copper clad aluminum) wire instead of solid copper for most runs and be fine, especially if just doing stuff around the house.
Good Tutorial ....Thanks. However I have got some Flat Cat6 cable and I want to crimp that and I'm struggling with that. Can you please do a video on that. Thanks.
On testing the cable, you can use two Raspberry Pi's (for 10/100) or CubieBoard 8's (for gigabit) and let the software to tell you if the Ethernet connection is established properly (one LED on the GPIO pin is enough)
Isn't the coloring order totally irrelevant if you do it the same way on both ends? ಠ_ಠ
Yes.
Unless you want a crossover cable.
technically, however the order is designed to provide minimal interference and best throughput. This becomes more important with Cat 6 and up cables.
yes and no...
the signal goes in an inverted polarization over a twisted pair, so the the magnectic fields cancel each other...
If you keep the pairs as it goes it shouldnt have any problem with performance
If you don't keep the pairs, you could end with some crosstalk, that could reduce the maximum lenght of your cable. for small lengths probably wont do any harm.
There's also the fact that this is a standadization, so anyone can understand your cabling and it is easier to troubleshoot problems...
(sorry for any missused term, english is not my native language)
Guilherme Freire The purpose of differential pairs is not to cancel out the magnetic fields, but to reduce interference. The information is carried by the difference between the lines and because the lines are close to each other, or in case of the cable twisted, the interference signal affects both lines in almost the same way. The signal is sent with opposite polarity on the two lines. On the receiver end the negative one (usually) gets inverted so both signals are the same polarity but the interference signal is now of opposite polarity. The signals are then added, with the effect of doubling the level of the wanted signal and removing the interference.
do you still need a repeater for really long cables?
the string is for striping the jacket back. don't trust the stripers. they'll nick the pairs. You'll get shorts or crosses. use the striper grab the string and pull back to strip the sheath then cut off the excess and put your end on.
ty
No it's not. It's a messenger for pulling the conductors through the outer jacket during manufacture but hey you can use it for that if you wish to distort the fuck outta the conductors in the cable.
What you do is use the strip tool to SCORE the jacket then you bend it until it separates.
Linus is so f'ing incompetent he didn't even manage to get the conductors to the end of the 8p8c connector and if you look in the video at 4:57 you can see only one of the two prongs actually hit the UTP strand!
Totally incompetent yet he's arrogant enough to come on here thinking he knows how to crimp properly.
JOKE
If you are really paying close attention Linus is not the person who is crimping this cable. All he did was voice over while someone else did the crimping (which person has much fatter fingers than his wearing a sweatshirt and not a tee shirt that he has on and wearing different watches)
I got a 100ft Ethernet cable for $8 from work at 5% over cost, So 1000ft at $100 is actually an awesome deal considering that 100ft retails for around $70-80
100 ft cables are $12-13 on Monoprice :|
teferi456 markup is crazy in IRL stores.
HOLY I thought this is a Linus Tech Tip video.... NCIX man... whoa.. good'ol memory
I KNEW it - Linus and The Cable Guy *are* the same person. Scary :D
Qain's video is so much better. Still, good job, guys!
Linus, you missed one HUGE thing: which way the plug sits in relation to the wire color code. Also, the difference between the A and B standards.
Will you mail me my geek badge? I have made lots and lots of RJ45 cables for countless customers. And how did I like doing this? I HATED IT WITH A PASSION!
I did this already & it worked!
When was this filmed lol? LinusTechTips has his old watch and just a couple fewer gray hairs
you can also use green stripe, green, orange stripe, blue, blue stripe, orange, brown stripe, brown tia 568 a standard which we use in canada
I did this in my networking class in high school and it was a pain in my ass. For the life of me I wasn't able to get the cables inside the plastic in the right order. I had it in the right order before it went into the plastic but once it went inside it got completely out of order.
Good falsetto! Made me smile! I appartently bought a Farady cage house. So by by wireless and hello faster, cabled connections. Might be cheaper making my own, certainly can control length. What about new docsis 3.1, will cat 6 handle that?
where was this video as i needed it?!?!?!?!
I just made a T568-B patch cable while drunk off lone star. I am legend raaaaawrrrr!!!
1:52 I have made speaker boxes out of cardboard before lol it actually works pretty well.
That's just the cabling pattern? That's a relief.
I looked in to some diagram way back, and it was confusing as hell. The first end was Orange with Stripe, Orange, Green with stripe, blue, blue with stripe, green, brown with stripe and brown. At the other end was a whole lot cluster fck that's so very different with the first one.
it doesnt matter if you make both ends the same tho. Unless you want a cable that does crossover, but routers do that themselves these days.
Just do it with solid and striped of the same color next to each other to not have performance issues.
Richard Smith Each pair has a different amount of twists on it so that different pairs don't crosstalk, and data is sent as differential signals over twisted pairs - mixing wires is a bad idea. - you CAN get away with just any old colour matched on both sides for slow speeds and short distances, but once you get gigabit across your house, you want the correct pairs or you'll start getting a lot of errors that are hard to diagnose when the fridge turns on or lightning strikes.
Linus sings like an angel, lol
MJDHX maybe he is IL CASTRATI
one question i havea 25m ethernet cable that my cat bit and cut it, can i buy the plastic little thingy and just make a new cable from the cut? WILL IT HAVE the same performance? even if its nanoseconds of delay will it be slower? i JUST want to know the truth.
Do the colors have to be in a specific order when they go in. Like say red, blue, green (THIS IS AN EXAMPLE) like it was placed in the video but say I do something like green, red, blue. Will it still work?
I bought a kit and ethernet, tried it out.. and yea. I think I am just going to buy mine pre-made. Not worth the effort for normal runs IMO. Will keep it for wall fishing and long runs.
I do this for a living.. It depends in what country your live in.. Mainly in the U.S we use the A side color code which is the one Linus did.. But in some cases the A side is used.. It also depends on what cable your using, cat 5e is the quickest one.. Cat 6a uses a slight different rj45 with 2 extra steps but overall the same concept
RIP NCIX
This is for a patch cable? i.e. computer to computer? Or from router/switch to computer?
I've bought a 30m terminated length of flat cable, but I want to shorten it.
I have the tool and rj45's, but the cable grip won't catch the flat cable.
I've googled for a solution, but found nothing, can you help?
my entire network is set up with custom cat6 cables
also cat6 is way harder to work with than cat5e since the devider in the middle is in the way when putting the pairs in order also the thicker wires makes it harder and that the devider is sometimes in the way when crimping and then the plastic bit pops out when done
Pro tip: Instead of cutting straight, cut diagonal so you can put one cable in its channel at one time instead of trying to get them all in at one time.
Does the length of the cable affect speeds? For example, if I were to use a 1000ft cable to connect to my neighbour down the road's internet. Would it be SLOWER than if I were to buy my own internet and use a 2 ft cable, within my own house
yes it does, on every cable there is written a number, a lot of them numbers, for eg. 100 meters (< what is this meter yeah?) there is a specific loss of speed, there are different cables for different purposes, and different costs as well
Depends on the cat of the cable, but I believe 1000 ft (what is ft?) is too long.
What's the correct order for the wires in the plug?
Did you find the order yet?😆
Is there any issue if it will be a Power Over Ethernet cable?
Are there better quality cat 5e manufacturers than others? I need some really good cat 5 for IP 4K cameras.
Can you make a video of how they crimp them in a factory environment?
+Roy Staggers wha.... XD just wandering how a machine copes with terminating so many wires.
this is the basics in networking classes
Can you do a video crimping some CAT6 shielded with that annoying cross thing in the middle? I have no frikin idea how you are supposed to terminate that without making a massive mess lol
I would have gotten in so much shit when I worked for at&t for stripping a cable the way you did. Yes you can use that tool to strip the sleeve off but you must pull the nylon thread to split the sleeve further back and cut off where you did the first strip. Of course you wont get a short from that first strip but you will open the pairs up to the air/moisture. that style of stripping tool almost always cut the insulation on the pairs. All it takes is moving the wires just a little bit to open the cut the rest of the way to where the copper is showing. This is coming from an engineer at a wiring harness manufacturing plant. We make harnesses for Caterpillar and EMD. If we did cut a cable or wire we have to put glue lined heat-shrink over the area. Even then most of the time we had to trash the entire cable because most cables we were not allowed to repair in that fashion. I love you videos Linus but if you are going to show people how to do something show it the right way.
Which tool are you referring to? The one shown at 2:50 or the one shown at 3:00 ? I work in a hospital, IT department I'm sure you already assume, and we use this tool (www.fullcompass.com/product/382026.html?gclid=CIG6vdW8kMICFRPItAod4ycAHA).
What Linus showed or did in this video is not done wrong or incorrectly. Here at the hospital, and in all of the business's I've freelanced in, we use the method and tools shown here by Linus. What we do not do is make our own male-to-male (or female-to-female) cables. We only terminate our own cable when we're running network drops (running cable from switch to wall mount). The reason we don't make out own male-to-male cables is because they're not as good as the ones made by professionals such as yourself. Cables made in this method can be buggy, can be poorly made, and can fail. Which is why our switches are filled with quality, professionally made, cables that you and your colleague's make. Although you may make wire harnesses instead of Cat5's, but my point is the same.
@3:00 and @2:50 The blade tends to damage the pairs allowing air/moisture inside the strip. I have personally went out on so many service calls I cant even begin to count because moisture has caused a wire to corrode and break or cause a high resistance fault. Indoors the cut wouldn't hurt anything really. But in a wall or attic it can be pretty hazardous. My cat5 cabling comes from working at at&t, doing home networking, and installing security systems. I would not use the blade you linked to for anything more than starting my strip. P personally I would just use my snips to cut into it and pull the thread back. Then I would cut off where I entered the cable. Then the jacket to prepare for the connector. My manager told me that we were flat out not allowed to use that as our finish strip due to the massive amount of issues they were having. real world stats from a massive company that logs every little issue a tech finds on repairs.
Justin Barnett
You act like we hack saw the cable. It only takes one rotation to remove the outer tubing. I'm also an engineer, electrical engineer, and the tool I listed and the one from 3:00 are common and recommended. Not so much the method with the crimper Linus showed, cause that tool's a bit barbaric for stripping, but it's still common and not really an issue. If you're worried about the corrosion of the cable, then you've got some butchers at AT&T. For the copper corrosion to be a real concern it would have to be in a very damp place or just tossed into a puddle and left there. Like I said I work in a professional environment, and always have, and that shit don't fly. If an area is so moist that the copper is going to corrode, then the building is probably filled with mold. It's cool that your manager at AT&T is used to having issues from poorly made and/or poorly installed cables, but there is nothing wrong with these tools. If you prefer to not use the tools because you don't want your pairs' insulation compromised, that's cool, but cat5 terminating isn't as difficult as you're saying it is.
Those tools were what was causing the issues. If you nic the insulation on a pair and then work with it it will almost always expose the copper.(really depends on the cable brand and types of insulation used. If it was winter it was almost guaranteed to break.) The tool you posted might be okay to use but the yellow one he used the blade is to deep. At my work when we setup the machines for stripping wires they don't cut through the outer insulation. It just scores it. Then its pulled apart. not cut through at all in any way to ensure nothing could happen. My experience is from 2 fields that are miles apart in terms of how cables are managed and worked with and both companies when it comes to perfection will not cut a cable (not just talking about cat5) using a blade like that. It would only be used to score it. Like I said before it is fine indoors for things that don't matter but I build harnesses and run cables that are meant to last 30+ years. The fact is you work in a nice climate controlled hospital. The stuff I deal with is in trains and heavy equipment. Hell even some of the harnesses I've worked with are in submarines. In areas that have to work no matter what. I guess my high standards are to high for a hospital or the IT field your used to. But for telecom work that's outdoors and in heavy equipment where one harness needing to be replaced would cause a piece of equipment to be completely tore apart and have days of downtime over something that could be so minor as cut insulation from carelessness... You don't have to deal with extreme temp changes. The cable does. When the insulation gets cold it contracts. It will open up any small cuts.
Justin Barnett
So wait:
"Like I said before it is fine indoors for things that don't matter but I build harnesses and run cables that are meant to last 30+ years. The fact is you work in a nice climate controlled hospital. The stuff I deal with is in trains and heavy equipment. Hell even some of the harnesses I've worked with are in submarines. In areas that have to work no matter what."
I would say that Linus's office is probably not in a train or a submarine, nor does it run through any heavy equipment. That's all I've been saying, that Linus is showing how to properly terminate a cat5-6 cable. So since damn near none of Linus's viewers are going to be making ethernet cables for use in submarines, and if they are they probably already know how to do it, that Linus just showed the correct way to terminate an end. Your method may be needed for the much more complex wire harnesses used by Cat and EMD, but that would make your method a special case use.
may you also make a video for shielded cables? Because i need to crimp a cat 6 s/ftp
does the white cables have a specific order too?
Linus missed his calling. He should have been a mime.
Actually the color order doesn't matter as long as you do it in the same order on both sides. But if you need to modify the cable later, then it would be better to sue the color order standard(mentioned in the video).
This was a painful process, organizing the cables in the right order was one thing, but keeping them in that order as you insert it into the jack was painful.
I wonder why this video have so "few" views. I mean Linus constantly brings up stories about NCIX and it's not rare him saying that he was a host of the youtube channel.
do the cat5 rj45 plugs fit on a cat6 cable? i keep seeing and reading that a ''spacer'' is needed or a specific cat6 r45 plug. Is that really true?
I like to think I know fairly enough about PC hardware and quite a bit about the software stuff, but I'm just a dud when it comes to networking.
My only skill with networking is the windows 7 troubleshoot option, and if that doesn't work, than I just unplug the thing.
Oh yeah, and my roll of unnecessary cable is about 5m, but that has to be there, it looks more badass like that :D
I like how the editor cut Linus off at the end
One more reason to do it yourself is to save money. I have seen cables in stores ready made but they are so over priced when you think about it. You can get bulk cable cut at most home improvement stores what ever length you want. It will almost always be cheaper than buying them ready made especially when you get to name brand cables. The connectors aren't that expensive either. The only reason I would ever buy one ready made is that I find crimping a crossover cable frustrating. I can do a patch cable easily enough but it will be at my own pace. My problem with crossover is still having the ends of all the wires even when it comes time to crimp the end on. I am sure that I am not the only one who finds that frustrating.
I had to do this a lot when we upgraded to Cat 6.
No clue what I’m doing wrong, but I have to do 50 ends before I get a cable that works. It’s every single time
Which company makes speakers out of cardboard?
Didn't Tek Sydicate do this one already a couple years back? :P
Looks like a nice crimping tool but NCIX does not seem to carry it anymore. Does anyone know the mfg/model or where to buy this tool?
Linus making look easy but my friend I tell you this whole process is pain in an ass. Once you punch wire you will have difficulty for copper to get contact with respective colour wires..I always miss the mark by mm.. It is simply nightmare for me.Tks Linus for sharing this beautiful classic technique.
Linus you forgot to mention something. You have Straight pairs and Twisted pairs. But at least i know you did twisted. You could of mentioned this on the vid.
i work for a Computer Technician and we work at a private school. he has the easy job of crimping them, i have the hard job of running around in the crawlspace and handing him the wire into the right room...
Any tips on dealing with smaller gauge cat5e cable? I've had no issues crimping cables in the past but found it almost impossible to get the (most likely 24AWG) wires to stay in the correct order while placing the connector on, they just aren't rigid enough. My current plan is to get some keystone jacks as a workaround but I'd like to know if there is a better solution. (I cannot just change the cable as it is fixed in a wall)
you can get connectors that have sleds so you dont have to hope you get it right
Justin Barnett Thanks for replying but I don't really understand what you mean by sleds, are they a special type of connector?
Its a little plastic sled you put the wires in before you insert them into the connector. So that you don't have to fight and hope they don't get out of order. These are similar to what I have www.monroviamac.com/RJ45-CAT5E-8P8C-Crimp-Connector-for-Stranded-includes-insert-guide-50-pieces-per-bag-Prodview.html
Justin Barnett Ah OK now I see what you mean, that's a pretty clever idea, now to see if I can find some here! Thanks for the help.
Its no problem. I've been using the other type of connectors for years and then I found these. Such a pain saver
"Ape people of the Congo nebula" 🤣
