Worked to add another port on a QNAP TS431XeU. I dont have a 10GB switch so its currently working at the 1GB speed.

These SFPs will not autonegotiate. I have to disable negotiation which limits me to 100Mbps with some of my devices. Mikrotik switch.

Worked perfectly. Just slid in the module, plugged in a cable, configured the port and it was off and running.

I have a few Linksys managed switches and a few smart switches (similar to a managed switch with no layer 3 functions or console port). They primarily use traditional copper ethernet cables, but they each have two SFP ports for fiber. In theory these can be used for any purpose, but in practice theyre best saved for when copper cannot cut it. I use them for 30-40 meter runs in my home that get snaked through the garage and end up under baseboards. Fiber is really thin, so it can fit under the baseboard. Fiber is immune to crosstalk, so the various runs being right atop each other wont interfere. Of course another use for be extremely long runs or runs through an industrial area with loads of magnetic interference or other issues. Lastly, fiber doesnt conduct electricity, so it wont spread havoc if a connect device gets struck by lightning. Anyway, these SFP modules just plug in and work. I used Monoprice LC to LC fiber and these on both ends (in Linksys switches). Works great.

Does the job and negotiated at 2.5Gb on my Ubiquiti gear that doesnt officially support 2.5.

I ordered the ipolex Gigabit SFP Copper RJ45 1000Base-T model and this works with my MikroTik. I had to make some changes on the OS for it to communicate with the device. If you have issues with it just seeing activity you may need to turn off the auto-negotiation feature on the port and set the speed to 1GB for it to start working. This is what I needed to do. After this it started working without any issues. So far everything is working as described and getting the full speeds listed.

Does exactly what I need it to. Runs a little hot but thats typical for this kind of module. Ive bought 4 of these so far and only one started acting up a few months later. Replacement process was pleasant and professional and all are running strong.

I bought this for my Cisco 3750 Switch and it worked well. It also worked with Netgear managed switches that I have.

These wouldnt remain connected between Ubiquiti Edge Router 4 and US-8-150W switch. Oddly, I had a SFP+ patch that isnt supposed to be supported, but it did the trick.

Worked great for me! 10GBe on an old server card I got off eBay
