Very instructive videos as always, sir. It's also worth mentioning that, for example, Cat 5 cables use only 2 out of the 4 twisted pairs to reach 100 Mbps speed and to achieve 1 Gbps speed, all 4 pairs must work flawlessly or the speed will fall back to 100 Mbps.
i last used a cross over cable in 2002 i think to connect a win 98 computer directly to a win xp computer and share the dial up internet and files from new win xp pc. a year later we got DSL installed in our city and i got a router.
I used to do the job of telecommunication engineering in Taiwan, and made a lot of Ethernet cable. It’s the first time I understand which is which instead of just verbatim and didn’t know why! Good work!

@@PowerCertAnimatedVideos Hey. My enemy neighbours are using Illegal Signal Jammers against me, it's stopping me from attending online classes. Which method can bypass signal jammer? RJ45 cat7, way to go? What you think? Or should I call cops on my neighbours, but they will lend in jail for 5 years! Which I don't want!
S(hielded)TP is not the same what F(oiled)PT is. In STP shield is made as metal braid/mesh. FTP cables has metalized foil. Differences is that the STP needs to be connected with ground to work. FTP doesn't need (but can be if cable has special conductor strand) to be grounded because metalized foil distracts EMI on its surface. FTP should not be used whitout actual need; they can self-interfere. CAT 7 and 7a are not TIA/EIA standards and it are not backward compatible with 8p8c connectors. These are designed to use with GG45 or TERA connectors. Propper replacement for CAT 5e are CAT 6a and CAT 8 Class I which are use 8p8c.
German HD-SatCom engineer from the media industry (actually specialized on fiber optic connectors for SMPTE311 (Lemo,Neutrik,Canare) here: Don´t forget that the most common used RJ45 connectors on Cat7 declared cables (min. 600 class F -1000MHz class FA), will throttle the performance to ~ Cat 6/E. You will get the same 10GBit speed, but the operating frequency of the whole network distance, despite the usage of the better Cat 7 cable is shrinking . (Like running through a wide corridor, just to be slowed down by a small door) But that's a good explanation. Thumbs up.
Something not covered in this video, and very important for making patch cables, is the difference between solid and stranded wires. Some cable ends work well with either solid or stranded wires, while others only work well with stranded. In general, if you're making patch cables, go with stranded. Beyond that, if you're wiring inside the walls, make sure it's riser rated. That just means there's something (typically a string) inside the sheath that physically supports the weight of the wire other than the wires themselves. CAT6 comes in riser-rated varieties, but it's also inherently suitable for in-wall wiring by design, as there's a plastic separator between pairs that effectively supports the weight of the wire as well. If you're wiring a commercial building, you also need to make sure the wires are plenum rated. That means the outer sheath is of a material that will not catch fire when subjected to extreme heat (it'll just melt). The only other thing I'd add is that all modern ethernet switches automatically detect whether a cable is straight through or crossover, and set up the connection accordingly (it's called auto MDI-X). Even a lot of ports on NICs and laptops support auto MDI-X. So it generally doesn't matter which cable type you use, unless you're connecting older hardware.
You are a life saver this video is just spot on with all the categories you have mentioned you have given explanation and have said what’s the speed it goes at on a local area network.
Thankyou for this video. I am taking network essentials in college. The textbook we use is quite scatterbrained, so I watch your videos to get to the point.
When I used to pull cable, I can;t do ladder work for health reasons now, it always specified that we use STP. Especially if there were fluorescent light ballasts in the ceiling. Good video and well explained.
I'm binge watching, too... Whether you're a technician or an average Joe, there's something for everyone, even if you know this stuff already. Thank you for these awesome presentations! By the way, I saw a video of a Category 8 cable being prepared. Each pair is shielded in addition to the bundle, and that serves a secondary purpose as the second wire in each pair doesn't usually have a stripe. The narrator indicated that the dyes used in other cables for the stripe can cause less than optimal results. Has anyone else heard that?
The STP you describe isn't an STP cable but an FTP cable. STP is similar to FTP but FTP only has a fieldprotection around the cable and STP has a fieldprotection around the cable and fieldprotection aroud each pair.
Hello dear sir! Please make video on Network Security and Cryptography. This channel helped me a lot. You are the true teacher. What a explanations. Thank you for saving my life

Crossover cables are more of a relic from the early 2000's at this point. My OG Xbox require them for systemlink. Everything else that I have can communicate with them over a standard cable.
I watch your videos since the textbooks do a poor job on layering subjects in a cohesive manner. You are a fantastic instructor and these videos are painstakingly edited with amazing quality and animations.
If someone don't want to watch whole video, Straight-through : Both ends T568A or both ends T568B, connects dissimilar devices, such as, pc to switch Crossover : One end T568A, other end T568B, connects network intermediary devices,such as, switch to switch
Actually, the other type of cable that you were showing was an FTP (Foiled Twisted Pair) cable. An STP cable has a woven shield around it. And also, there are other types of cables, too, like SFTP, or SSTP, where the second letter refers to the method the individual pairs are protected/
The funny side is that when i was a beginner in hardware i laughed at ftp telling the guy how can a cable enhance file transfer protocol and not http 😂
Super well explained 👍 now I understand why should I use at least CAT 6 UTP cable in my house. Hope the cable company know this and don't use cheap cable.
Note that while Auto-MDIX is an optional feature of the gigabit ethernet specification (IEEE 802.3-2008: "Implementation of an automatic MDI/MDI-X configuration is optional for 1000BASE-T devices"), most gigabit ethernet interfaces do implement it, so in most cases you will not need a special crossover cable
568 color wiring order really doesn't matter much anymore. The CAT quality is so good so making sure both ends are the same & pass a cable tester check, it's good.
While technically true... but now a days any Ethernet device has straight to cross detection and will still function no matter if used straight or cross UTP cables .. since early 2000;s thats the standard as well auto detecting 10M, 100M, 1G, (10G) speeds / half or fulll duplex.
What I am wondering though is if the auto detection will require any additional overhead. If there is an efficiency that I can have I want to know about it. Removing the need of a process of needing to determine something that would be unneeded if wired correctly from the start sounds like an efficiency.
@@joeniemand5275 nope it's hardware detection. once you inserted the plug then the Ehternet chip knows it's pair configuration. no overhead no additional processing. it's a one time detection and then the hardware follows suit. It still does the same detection if your are putting in the "correct" cable but the chip still does same hardware config. the Ethernet chip has no preference, it does it's auto detection every time a cable is plugged in. (well a cable with a signal on it.)
Love these videos! Please do one with ip addressing (class range, CIDR notation, subnet mask range)? Can’t wait till everything’s covered really. Keep up the good work!
FYI>>> If your crossover cable is too short, you can connect it to a straight & both will be a crossover cable If you connect 2 crossover cables together the result is a straight cable. !
Some comments on here about crossover cables being ancient tech made me remember a time when a friend brought his pc to my home and we networked them together in the late 90's. Our NIC's didn't even have RJ45 ports by this point, instead we used BNC connectors.
I have seen several instances of existing cat5e networks capable of doing 10Gbit/sec without any lost packages or other quality issues. So if you have that at home and want 10 Gbit, try the existing before ripping it all out.
note to self and whom ever may need it: counting from the left the 568A is only different from the 568B because the first cable is swapped by the third and the secound is swapped with the sixth thats y i suggest memorising the 568B colour code
