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.

great video. SFP FSP SPF 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!

Thank you for enlightening my eyes with this tutorial.

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.

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!

Perfect, Thanks for sharing.

Great clear video thanks

Great video and very helpful to me.

Now I have learned both how to setup network connections and not get a sun burn as well.

I see the light!!! thank you

sfp+ with rj45 is very hot, if you pump from 200GB, sometimes the network falls off, you need to additionally cool it

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.

Thanks, bro!

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 ❤🎉😊👋✌️👍

Haha I see what you did there (✈️) Great video, thanks!

If two 1GB switches are next to each other in the rack and both have SFP ports what transceivers / cable is recommended?

1:07 SFP, not FSP lol. Edit: great video, I enjoyed watching you struggle with that, turns out I’m not the only one. 😅

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?

Short, straight or twisted to the point.

My TPLINK router has a SFP port, can I use a SFP with optical port to connect the the optical cable from service provider ?

❤❤❤

SFP, FPS, SPF 😀

and OPP! yeah you know me!

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.

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

@BuzStringer

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.

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.

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.

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.

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.

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.

You managed to say SPF and FSP 😂

SFP not SPF.
