Hey Chris, I just wanted to say that your videos are excellent and thank you for the effort you put into them. I'm a freelance network engineer in the UK and your videos on all of the Ubiquiti products have been extremely helpful to me and the guys who work with me on larger installs. Keep up the great work!
Thanks for watching!
Hey Chris!
Telecom/fibreguy from Norway here again!
And I just wanted to point out a few things that you might want to mention in a followup/similar video in the future:
1st: SM vs MM ... You say that MM is more cost effective. Now this might be different in USA, but in here in norway and as far as i can know, europe in general, SM is WAY cheaper then MM. Prices of SFPs I do not know, but SM pigtails, cables and patchecords are roughly a third (or better) of MM, as well as you saied, spans can be longer. MM is usually 550meters (1500 feet or so), while SM is in the 100s of miles range. But that is greatly dependent on the SFPs in use. Also note that there are two MM standards, but im not sure if they are interchangeable or not. 62,5/125 and 50/125 (Micrometer core of the fibre/micrometer size of the entire fibre). So thats is worth checking as well when buying gear for a cable or cable for gear :)
2nd: You should never take out the rubber things from the SFPs, and the plastic caps on the patchcords until "just before" you are about to connect them, as dust might come into the SFP, and thus adding attenuation to the connection, and worst case that ive personally encounted, washing the connectors/SFPs removed about 20dB of attenuation.
3rd: As breafly mention in the end of #2, you should always clean the ends of the patchcords as well as the port you are connecting them into, it be a ODF or SFP or otherwise. Google "LC cleaning pen" or similar. ALWAYS ALWAYS ALWAYS ALWAYS!
It WILL reduce the ammount of support you need to by ALOT.
4th: You probably know this, but worth mentioning all the same ... MM always have gray connectors, both 50 and 62,5, while SM have either green or blue, depending on the type of connector. UPC and LC are blue, and APC and SPFs with "ALC" connectors (not sure if thats the correct term as we never use them) are green. And they are NOT interchangeable. APC are _USUALY_ on long spans with SPFs with high output, but not exclusivly.
Best Regards! Thomas!
Great info! Bottom line - clean your ends before you stick it in.
Crosstalk Solutions that's what she said!
what you call an "ALC" connector are known as "APC" (angled polished connectors) in the UK - green boot and strain relief.
Great info from Thomas indeed. I would like to add that working with fiber is a completely different ballgame then copper. In the professional world we have the mantra: test (laser), inspect (fiberscope) and clean. The fiber strand is smaller in diameter then a human hair, so any tiny amount of dust or debris will degenerate the signal enormously.
Also, ESD! I’m not one to be overly concerned with Electro Static Discharge, but SFP’s are sooooo delicate! You have to take precautions and pull out the old wrist strap.
Great insight. Thanks for your support and being so professional.
Hey Chris, I love all your videos. SSS - Simple, Step by Step, Straightforward. Big thumbs up to you.
Big thumbs up to you for having great taste!
Im from egypt and what i like in your videos is your simple language..i can understand most of your English so easy thanks to you...keep up the great work (thanks a lot MR criss)
+ahmed tarek Thanks for watching! Greetings from the US!
This video, and all of your US-8-150W related videos, helped me immensely. Thank you from a first-time owner of a UniFi switch.
I am installing 10Gtek 1000BaseT (copper) SFP modules into a US-8-150W. I could not find any instructions on how to do that on UniFi's site/documentation.
From watching this video, it doesn't seem it's necessary to power-down the US-8-150W (or your EdgeSwitch), before installing the SFP modules.
Do you know of any scenario where powering down either device would be necessary when installing/removing SFP modules?
Thanks in advance!
THANK YOU!!! You cut through the bull-crap and explained it in such a way that even a newbie like me understood.I just got into 10gbe home networking and this video helped me a lot. so I have my lines all as cat8, and my desktops as 10gbe multi-mode fiber.
Thank You
Thanks Chris, I was just looking at this. Perfect timing.
We have a site that we are adding cameras. There’s a total of three switches in three different rack rooms, With distances up to 1000 feet, luckily there is fiber in place. This will be awesome
thanks again!!
Scary tech jargon can make simple things seem scary. Thanks for showing how easy this setup is. (When using compatible components, of course.)
I really like Chris' videos. Always explained well.
Heya!
I am just started to learning about how networks work, and your video gave me the visuals I needed really much.
And you have a beautiful house! Thank you for showing all of that
Cheers - thanks!
Hey Chris,
Simple, Easy-to-understand, highly recommended video. Hope to see more.
Wonderfull Chris, good explanation for beginner like me and other thing I liked is your pronunciation, because I'm not fully english speaker.
I use the SFP port of my US-8-150W switch to connect to my ISP.
Works well!
Wow, that's actually the answer I was looking for, so actually it is the WAN post then, can you also manage that port?
I know it's been a year since you posted this, don't know if you read this, a big thumbs up.
But how about DHCP? Do you need something for that or do the switch handle it?
Thanks Sir, I'm now studying my Comptia network + , those infos helps
Hey Chris you must have known this happen. :-)
SFP are not quite that easy if you want it all to work happy.
The biggest this is compatibility, Ubiquiti Edge Switches don't like just any SFP's, they are fussy.
They can have bus interface problems as in 1 bus is used for one thing but SFP will use it for something else. Hence Ubiquiti will tell you that it it is unplugged but works fine or it will not give you the temp because that buss is used for something else.
Most makers will do a General Purpose that will work with the majority.
Then the next big thing is the speed with the distance, that will dictate what cable/fibre if you have that luxury.
If not you have to work with the fibre with the distance that will determine the light frequency or wave length (same thing) which some to most will argue about. (spectrum of light)
PS The Telecom/Fibreguy is correct with all the plugs.
And
Cisco have a good connector patch diagram for what is what and what colour.
Ciso are far more fussy with SFP's
You should have mentioned that the patch cord is cross over. Along that line, in a fiber optic installation with fiber patch panels on either side, please confirm that the strands should be straight end to end, and the cross over should take place in the patch cord.
The information is provided practical, simple and fast. Thank so much!
This was helpful to see the assembly process. Thanks so much!
If you have a 1Gbps SM SFP and you discover you have a long length of MM fibre, that you can't replace, you can use a Mode Conditioning patch cable in a pinch.
Basically just a MM patch cable with a short piece of SM fibre on the transmit side that provides an offset for the laser that prevents differential mode delay over long distances.
Great scenario to demonstrate fibre and SFP modules and that they're hot pluggable. PLEASE don't remove the dust caps of any part until you're about to connect - for example only remove the dust caps off 1 end of the cable while you plug it in, and then when you're ready to plug the other end of the cable in only then do you remove those dustcaps.
Multimode might survive some dust particules but degrade, but Singlemode the entire core can be covered by a single spec of dust.
yes
omg dude.. you really helped me out.. thank you for keeping it SIMPLE..
I am a beginner, its really very useful for me..... Thank you brooo
It was so nice to see your video, very simple setup. It always good to be same Speed, same mode on the both two sides. Recently UBNT stop providing Edgeswitches, it really puzzles me, cause I still use the old ES-8-150W switches and fs sfp in it. I wonder whether I should switch to a new brand switches.
So the Butterfly knife is used to protect for security breaches or is it for people that dont clear their cache before putting in a trouble ticket. Great video though! Broke it down nice and simple!
wow thank you! u really explained it well
I know this is an old video but I have questions. It's 2023 and I am adding connectivity to a new detached garage I am building. Friends strongly recommended fiber. I have a UDM Pro in the house. I am thinking 10Gtek SPF dual mode modules with a 40 meter outdoor armored duplex fiber optic cable with LC ends. On the garage end I am thinking of using the Ubiquiti UniFi Switch 8 port 150 watt switch you have in the video. It seems the perfect solution for an AP and IP security cameras.
RE - the fibre patch cables - the "white little plugs" are dust caps, yes they protect the ends of the fibre but more importantly they keep dirt and dust off the fibre ends. Dirt is 99% of the problem in fibre optics and therefore you should never take yer dust caps off unless you need too...
Hey Chris, best regards from Germany :)
I would tell you, that the SFP-Mobul A7446B from HP work also fine in the Unifi Switch 24 Port. also with Link-Aggregate, with this feature you have 2 GBit as Load-Balance. It is interesting when you have IP-Camera in this network an the NVR is on the other switch...
Loved your greenscreen background
Excellent house and window and environment
Great Video! Enjoyed the simple/clear explanations.
Very nice explanation and demonstration
Lovely
This video alone with fiber physical structure (layers) boom!! You gonna pass fiber interview question....
And if you add fiber splicing you're expert in Fiber IT dude
Prove me wrong "Mr Crosstalk Solutions"
Awesome content as usual! I am currently and drastically upgrading my home network. I work most often from home and my family can have as many as 3 or even 4 concurrent video conference calls happening. However, my network is target for performance and future proofing. I therefore putting infrastructure for 10g everywhere, while keeping existing cat 6 for devices that will never need higher speed, such as printers. I also taking the UniFi leap with APs, video, etc. We currently have fibre with 1.5 g and will get the expected 5 or 6 g service when available later this summer. I, like many others are waiting on the UDM SE, which is not available in Canada currently. I already have the XG 24 and 24 PoI enterprise switches. My question: how do I connect these two devices - SFP+ to SFP28? Will a UniFi DAC SFP+ cable do the trick? Or do I need an SFP28 cable? Something else? Thx
Why would you want to spend the money to use SFP? What is the advantages and disadvantages of using a SFP connection vs an Ethernet?
Josh Roberts On the unifi 8 port poe switch you loose a port for the network up link but if you use a sfp you get that port back to use for poe and with it having 2 sfp ports you can turn that 8 port switch In to a 10 port switch.
Exactly my question, so 1 Gbit SFP vs 1 Gbit RJ45, of course if you do not pull the cable longer than RJ45 can cope
If you want to run longer distances than Ethernet (SMF up to 120km and MMF up to 500m) but don't need higher speed than 1Gb/s or if you you are forced to run the cable through areas where the environment would influence electric signals in Ethernet cables due to strong magnetic fields. Large ships often have this issue and this is why you would use the cheaper SFP over SFP+ since they don't need the speed of SFP+ but the reliability of fiber.
There are only three reasons I can think of for using SFP and fiber. First, is length. Single mode can go multiple miles. I've heard up to 13 or more. Second would be for SFP+. If you want 10Gbit and any decent distance you need fiber and third would be because you can't run ethernet for some reason. Could be space constraints, electrical issues.
As far the scenario that Chris is showing, there really isn't a good reason to do that.
This is a great answer - in my scenario, you absolutely would NOT need to run fiber (unless for some reason you HAD to take advantage of all 8 PoE ports in my little UniFi switch).
Great video Chris, this is like connecting sfp modules for dummies!, super easy to follow, thanks for the amazon affiliate links.
Can you do a video on DAC cables as well (connecting switches , nas & servers)?
Thanks again
Cheers 🍺
Yea - I meant to mention DAC in this video, but forgot. I'll have to order a DAC patch cable and do a follow-up.
10Gtek also makes DAC (Direct Attach Copper) cables. It worked for me.
Great video! Keep doing the good work. Greetings from Méxicali México!
So, the UniFi Direct Attach Copper Cable are SFP+ (10Gbps). Yet the Hardware is SFP (1Gbps). Could you plug SFP+ into the SFP ports?
Hardware referring to is Ubiquiti US-24 Unifi Switch, and Unifi Switch L2 PoE (US-L2-24-POE). Both list "(2) 1 Gbps SFP Ports"
typically direct attach copper cables are a fixed speed meaning a SFP+ cable is only rated at 10gig and cannot be changed to meet the 1gig speed of the SFP port.
thanks for the explanation.
Love your videos As always
I have heard that sometimes even the brand of the SPF matters in some cases. Some brands don't work well with others. Is that true? I know it is a good idea to ask those questions when buying just to avoid having to send things back.
Hi Sir thank you for the video. Is there a process to enable SFP port?
So you had internet using standard ports and cables. You unplugged the cables, installed the SFP's and patched with fiber, Viola you had internet....? Why did you go through all that to get what you already had. Is it just a speed thing or is there more that this does for you?
You can also use an sfp to sfp cable instead of two modules.
Hey, Any chance you could do a video on using SFP uplinks to do link aggregation from a Edge Router 12 to 24 Port Unifi Switch? I can't figure out how to do it... Is it even possible?
you need to know also the wavelength for your SFPs. most common are 1310nm and 960nm
Can you do more videos on connecting Fiber between routers and switches? Love your videos!
Hi, great video. May I ask a question about the length of the fiber cable? Is it possible to use a 10m single mode cable with SFP modules that are rated at 20km? Would it burn out media converters on either end? (1GB converters) - Thank you!
Excellent! Very helpful. Thank you.
Hi, tks for the video. Would it be a good idea to follow up with a video on the fiber cables?
Wow, didn't realise it was that easy. What is the benefit though of a 1Gb sfp link over an Ethernet cable? (Cat 5e and Cat 6 can do 1Gb?). I'm no pro at this at all, genuinely asking the question.
No benefit for speed, but if you wanted the switches to be more than 100 metres apart, then optical fibre is the way to go, as twisted pair cabling isn't much good beyond that length at high speeds.
@@Tekwyzard ahh yes, fair point. I was picturing the switches next to each other. I forgot about longer distances.
very useful video thank you for your efforts. :))
i am ashamed that i liked this video so much, great explanation
Cheers...thanks!
Hi Chris, thank you for the video. I just want to know that if we have any FFTH optical by ISP, can it be connected directly to EdgeRouter via Ubiquiti U Fiber - SFP 1Gbps - SMF technically?
Or not because ONU (=optical modem) is needed to connection (OLU sends packages to all ONU and ONU checks and filters the packages which belongs to its) to and we can not bypass modem device in our infrastructure. I know there is other side, it may ISP doesn't allow user's devices.
based on what I understand is that SFP module should end to the other SFP module, right? but I've seen someone use the SFP module ending in a Splitter NAP Box, is that okay?
Hey nice video, you say mmf is for shorter ranges, what is the Limit here? i need to go like 150m, should be fine with mmf?
Hi Chris, great video as always, do you know if you can use the sfp connection between an Ubiquity gateway pro and a Poe switch .?
i never use fiber optic before. can can you make video about fiber optic. like the cable type and how to terminate fo.
i can teach you,i am ftth supplier from China,Email&Skype:Cindy@yingdapc.com,whatsapp&Tel:008618026920928
Thanks alot bro Was really helpful keep up the good work
I'm connecting two devices together. One Nokia device is capable of gigabit ethernet and has a 100/1000BASE-T SFP plugged into it. Will it talk to an RLH 10/100BASE-T card using a CAT5 or CAT 6 copper cable? or does the SFP on the Nokia need to be a 100BASE-T SFP?
Why was the PING time not changed but stayed at around 25ms when the optical cable was used instead of the copper CAT? I thought latency is greatly reduced with the SFP connection?
I have seen other videos where they will clean the tips of the fiber before plugging into the SPF, even on brand new cables. Is this necessary to do or not? I have seen fiber tip cleaner/kits range from $20-$200 and not sure if that expense is worth it for 4-6 cables.
Yes, always clean new cables, and the way Chris is doing it here is wrong, it is a typical IT guy failure, the dust caps (not rubber stoppers, as he calls them) must first be removed right before you're are ready to insert the optical cables.... I am working with fiber every day, and the most common failure, is IT Guys, the leave the patch cables, and connectors, without dust caps, finds and old cable in a drawer, wipes then of with a finger, ore in the shirt, and that is just making a bad connection, looking up a connector in a microscope is very interesting, when people think that they are clean...
What's the benefit of using SFP (so 1 Gbps) over normal copper Ethernet cables? (also able to do Gpbs, but no need to buy SFP adapters)
Hey Chris..thank you for this video.. would you please let me know when GLC-T is being used?
I have a spare EdgeRouter X and would like to use it as a smart switch. Is there any information on how to set it up and then 'program' it to allow certain ports to support specific VLAN's?
This might be a dumb question, but if your ethernet and fiber ports are both limited to 1Gb/s, what difference does it make?
such amazing video 👍
Im not sure I understand. If you have two 1 GB switches you can just take any plain old vanilla CAT 5 network cable and combine them. Why do you need these at all?
What about running fiber through conduit / tight spaces?
Can it be field terminated (like CAT cable)? So it can be cut to length?
How durable is it for pulling strength and around corners?
Thanks for the good content
I was looking to get buy a LC-LC fiber cable but noticed there are OM1, OM2, OM3, OM4. From what I can tell, they all support up to 10GB but at different lengths. For connecting 2 UniFi switches, does it matter which OM I get?
Can a SFP Fiber port from one switch to another be used instead of a Media Converter for long distance? Is there a distance limitation? It may sound like a stupid question but I can't find anything that indicates that it can.
Thank you! That was very helpful.
Thanks for the video!
Hi Chris, I have a question does SFP have the capability of auto -MDIX to sense of the fiber patch is flipped just like copper regular ethernet cable they can sense TX to TX and change one side to RX without making any changes to the cable itself. Thanks
What I was/am looking for if you could also use the port as a WAN port from your ISP, I found part of the answer in the comments, it works as a "port" in but can't really find if you can manage the port.
Hello Chris, what fiber should I run for the MM fiber? I ordered the Ubiquiti MM SFP's and have an 8 port unifi PoE switch and need to interconnect it to an 8 port PoE Edgeswitch. Any help would be greatly appreciated. Thanks!
@Crosstalk Solutions, I'm about to build my home network. The basic topology consists of a Google fiber jack going to a switch, ES-8 150w, on vlan 2 by Ethernet, connected to a router by sfp trunk, router-on-a-stick. Would this create any bandwidth issues of sharing the WAN and LAN on a single physical link?
Hey Chris, I have both the 10gtek sfp and ubiquiti sfp. I can’t use the ubiquiti sfp will not link actually work as cross connect between by us8-150 and the dream machine pro. Checked cables and 2 sets of ubiquiti sfp’s. Any tips?
Thanks. That was what I needed.
I'm planning my uni end of year project, IT infrastructure for 60 employees (2 servers and 12 printers too). We're a very Cisco heavy uni however I have been considering Ubiquite. Do you have any recommendations for 48 port Ubiquite with layer 3 functionality? Thanks.
Vey interesting. I do have a doubt. Can I use on my X520-DA2 SFP+ slot into my dlink switch SFP slot? Using what you recommend 2 x SFP and Fiber multimode?
Hi Chris, Great Videos. Can you link the Gateway Pro4 to the Unifi 24POE switch to use Wan1 as the link to the internet via SFP's rather than the Wan1 Ethernet Port?
Excellent video mate! :)
With a modem having fiber out, I should be able to go from the modem to a UDM Dream Pro for internet, and then to my switch of choice?? Right?
Hi Chris! Love your videos. I used this to hook up my Ubiquiti SFP+ DAC between my UMD-Pro and USW-48-POE Gen 2. However, I also had to add the ports to the LAN profile and then auto-negotiation still didn't find them and I had to manually set both ports to 1GBps even though they both support 10GBps. The switch didn't even have 10 as an option even though it's in the specs. Any thoughts on the auto-negotiation feature and the lack of 10GB option on the switch?
The Standard USW-48-POE (non-Pro) just have SFP ports (1G) and no SFP+ ports (10G). And it is known that the auto-negotiation goes wrong, most of the time. However, maybe a future firmware will make that better. But 1G DAC is stille better then 1G ethernet. So congrats!
Can I connect ISP's fiber cable to SPF and use Ethernet port in router and use internet? or SPF only intended to connect two switches together?
I was installing a VERY heavy Juniper MX router and it had SFP adapters in the router.
Nice, I am planning to wire with fibre between Edgeswitches
its worth it to change from Ethernet cable to fiber ? big difference ?
Thank you for this video...
And as alwyas, great video, still up to date. Question: Can I use and SFP to RJ45 converter that would give me essentially an extra ETH port on my edgerouter? I have no use for SFP port#5 otherwise. Thanks!
Yes, of course. www.amazon.com/s?k=spf+rj45&ref=nb_sb_noss
Hey
Does any config need to be done on switches when connecting them with sfp?
I have two aruba 2930s i want to connect. Are they typically plug n play? Like rj45?
Ty
hi , thanks for the vid, i have a dell switch , do you happen to know if there's anything to configure besides installing the module physically ? :) thanks
Hey Chris, Do you know how to connect UMP-PRO (SFP+) with UniFi Direct Attach Copper Cable
to US-16-150W? maybe setting UDMP port to link speed of: 1Gbps :D
Thank you for the video , I have question what is different if u used UTP or Fiber connection between the tow switches. Is it faster ??
In this demonstration, it looked to me like the ping actually increased 1 ms after switching to the fiber. I've heard that fiber is ideal for handling many connections at a reasonable speed while copper is faster for small networks without too many nodes active at once.
hello great video, take me out a question,
As for cisco devices two switches of the same model sg220 using mini gbics I can use patch cords MM Duplex LC / LC? to UpLink?
What is your deal with Ubiquity? I thought this was about SFP.
already shared with my SFP customer,i am SFP supplier from china.
The Unifi modules are still not available. Can you give me a link to the ones you used? I am connecting a US-24-250W and a US-8-150W with this fiber: Multimode 62.5/125 4 Fiber Indoor/Outdoor Plenum LC to LC.
All links are in the description of the video - thanks!
