- SFP, or Small Form-Factor Pluggable, connections are a type of interface used in networking and telecommunications equipment to transfer data between devices. They are commonly used in fiber optic cables to transmit data over long distances at high speeds.
In this video, we will be covering the basics of SFP connections, including how they are used, the different types of SFP connectors, and the benefits of using SFP connections.

The most important thing that wasn't mentioned is that 10Gbit SFP+ RJ45 modules are becoming hot as hell when working at big speeds. So hot (95-100°C) that they (very often) cannot be used in fanless switches due to overheating. Switch can read temperature sensor in such SFP+ module (for example in Mikrotik S+RJ10) and it will disable link if module is overheating - breaking our network experience. In my tests on fanless Mikrotik switch the SFP+ module was overheating just after several minutes of 2Gbit traffic. So if you want 10Gbit best is to avoid RJ45 (use fiber instead) or have cooling in place.
3:42 The 28 in SFP28 stands for the maximum data rate of the transceiver, which is 28 Gbps. This means that SFP28 transceivers can support speeds of up to 25 Gbps, which is significantly faster than the 10 Gbps speeds supported by SFP+ transceivers.
SFP28 transceivers are typically used in high-performance networking applications, such as data centers and cloud computing environments. They are also being used in some high-end consumer networking products, such as gaming routers and switches.
The name SFP28 is derived from the Small Form-Factor Pluggable (SFP) form factor, which is a compact and modular transceiver interface. SFP28 transceivers are available in a variety of different optical and copper variants, which makes them compatible with a wide range of networking equipment.
great video.

dude is on fire. keep up the great work,
Excellent video, simple explanation and exactly what I wanted to know within my attention span! THANK YOU!
Glad it was helpful!
sfp+ with rj45 is very hot, if you pump from 200GB, sometimes the network falls off, you need to additionally cool it
1:07 SFP, not FSP lol.
Edit: great video, I enjoyed watching you struggle with that, turns out I’m not the only one. 😅
If two 1GB switches are next to each other in the rack and both have SFP ports what transceivers / cable is recommended?
I just worked as an IT Infrastructure for about 2 months and the network guy always ask me whether we have any stock of SFP s, I just confused since all I know the switches have its own RJ45 ports, thanks for the video, now I know what it is and how it worked. lol
Ha, that's awesome. for a good couple of years I avoided anything with an SFP port becuase i didn't know how they could be used. Then there was the "Oohhh that's cool" moment.
SFP28 is indeed 28Gbit just like 1gbit transceiver is NOT actually 1gbit. Look at the transceiver itself it will say a number larger than 1000 or 1024. I think it's like 1.12 or something like that. I don't remember someone will correct me because they know what it actually says and theyll try to infer that means they also knew why 25Gbit SFP28 is called SFP28 instead of 25 but they didn't make the connection till I mentioned the raw speed of a 1gbit transceiver.
Thank you for the explanation, I've been in networking for years, but not since Fiber rolled out, and this helped me a a lot , thanks again!
Glad it helped!
Short, straight or twisted to the point.
SFP, FPS, SPF 😀
and OPP! yeah you know me!
Now I have learned both how to setup network connections and not get a sun burn as well.
Thank you for enlightening my eyes with this tutorial.
Are all SFP ports same(standardized) on different manufacturers switches/RTUs? Can you plug any SFP module you buy in any switch/RTU, for example industrial switch, and will it work?
Technically, yes. Historically there have been some quirks when 2 different brands don't play nice together for no reason. But that's very uncommon these days.
Haha I see what you did there (✈️)
Great video, thanks!
There are also SFP modules for RJ45 2.5GB
I got a couple of these transceivers on Amazon for a Bpi-R3 and they only work when the other end is 2.5Gbe, nothing slower.
Ended up wiring one to my cable modem and the other to my desktop motherboard port.
SFP not SPF.
Yeah my brain failed a couple of times :(
@@BuzStringer still a great video
@@grandmasterbash thanks :)
Lol
@@BuzStringerspit out the model name of that switch real quick tho lolol
Litttle addition , there are adapters SFP+ ( 10 Gbit ) to 40 GBit SFP+ and QSFP+ to Rj45 as well or breakout cables QSFP+ to 4 times SFP+ ( 10 Gbit ) which can use an SFP+ to Rj45 as well
You can get used Server QSFP+ Nics very cheap nowadays , you can get a pretty fast NAS with if you can use 4 or 8 Lanes PCiE 3.0 for the NIC card ua-cam.com/video/5MSk3_kkvK4/v-deo.html
3:43 Ngl. I laughed harder at this than maybe I should have. 😅 The delivery was the key.
Single mode fiber to future proof for 100G (later swap transceivers) for short runs under 125 feet? Can single mode os2 pair with SR type sfp+ transceivers?
Great video and very helpful to me.
Perfect,
Thanks for sharing.
At 5:20 "But they are not interoperable. So you would use both MMF or both SMF transceivers in one cable run."
Really? "Plain English" this is not.
"But they are not interoperable." That's great. Its meaning is clear and simple. What follows, restates the context and adds clarification.
"So you would use both MMF or both SMF transceivers in one cable run." This uses two positives without a clear emphasis on their distinction. (The speaker could have paused and emphasized the "or", or also, even explicitly used "xor" instead.)
The '"or", in this case, is not your common, everyday 'OR'; It is your logical, more specific, technically oriented, mutually exclusive 'XOR'.
A simpler and far clearer expression would be "So you would not mix MMF and SMF transceivers, in one cable run."
Making videos is an exercise in communication. It is not a matter of simply delivering 'content'.
Simply delivering dialogue, despite it (hopefully) being 100% accuracy, misses the point.
The dialogue 'paints' content being presented and its delivery should be tempered to maximize that objective.

My TPLINK router has a SFP port, can I use a SFP with optical port to connect the the optical cable from service provider ?
Great video, thanks! Quick question though, if I'm only running about 10 ft of cat 6 ethernet, Will I burn out the transceiver by using one rated for 100 m?

Thanks, bro!
From my understanding, SPF ports are the answer to people who have fiber optic Internet, and don’t want to use the providers router and can use their own if that personal Rado has the SPF porch? For example, I have AT&T Internet, so I just take the RJ-45 cable connect it from the Internet box mounted to the wall from the provider then take that cable connected to the SPF connector then take that then connect it to the modem.? I’m hoping I’m right about that so I never have to deal with the providers modem anymore.
sfp onu stick is what you need
Isp use a pon system. It's not Ethernet, and the onu is managed from the olt (sort of a switch). Ask them and they might have an onu in an sfp for you.
Those RJ45 SFPs have that gold lever on them to let you pop them out.
Great clear video thanks
I don't get it. What's the point of the transceiver?
The transceiver converts whichever cable to SFP, so you can plug fiber into one port, ethernet into another and it just works. Don't need to buy a fiber switch or ethernet switch.
So an SFP switch doesn't really care which type of cable you are using, you can use whichever is best for your setup.
Short high speed fibre, a bunch of Ethernet clients, and long range fibre, all working together in the same switch.
@@BuzStringer awesome. Thank you. So it's versatile. I didn't realize that.
But what's really got me tripped up is that transceivers send and receive electrical signals. But any cable, whether it be ethernet, fiber or whatever, has electrical signal being sent through it via the server/host device. So, for example, why does a Direct Attach Copper (DAC) or any other cable need the transceivers?
❤❤❤
I am new to this and want to grasp a better understanding. I can understand stacking using two or more switches, but can you stack a router to a switch using SFP? What are the pros and cons about that
You can, if the router supports SFP.
The benefits are only there if the router is doing any switching or being used as a wireless access point, or has a modem connected to it. They are the same benefits as linking two switches.
If the router is just holding the DHCP table and not handling another network traffic then there is no benefit, the DHCP table is very low traffic.
You managed to say SPF and FSP 😂
I see what you did there 👍
Is there any harm using SFP module at one A end and SFP+ at Z end?
You would be limited to SFP speeds, that should be it for performance. Pricewise, you are paying the SFP+ premium on the other end for no benefits.
Awesome 😎 i learned basic from your video last night and after Google study overnight i got this piece very interesting and got a complete solution for using....many thanks and greetings and blessings from Bangladesh ❤🎉😊👋✌️👍
thank you!
@@BuzStringerYou're welcome, Sir..... You're really awesome 😊🎉
I see the light!!! thank you

You are trying to make it simple for persons to understand but you are saying SPF instead of SFP ports. You will confuse people.
Yeah my brain failed, I think I said every combination of those 3 letters
