Cable Matters 1000BASE-T Gigabit SFP to RJ45 Copper Ethernet Modular Transceiver for Cisco, Ubiquiti, TP-Link, Huawei, Netgear, and Supermicro Equipment

Good quality SFP+ connector. Works as expected, easy to install. Works at expected speeds, and the price is right. No complaints here.

Cheap and works two great combinations

I get 1GB speeds without any additional configuration needed on the switch side. Plug slides in easily and can be removed with the golden lever on the end. Doesn't run hot in my rack.

This was a life saver for my 10G internet. It has been working for months, it has been fine. The price was right. Worked with my UI products. No install problems.

This worked perfectly for my setup. I used it to connect one Ethernet switch to another and then to my PoE switch—no issues at all. It was truly plug-and-play, and the connection has been rock solid. Great quality and compatibility.

Cable Matters… what happened??Not only did both modules not work, but the top one became stuck in the SFP+ port in the Ubiquiti switch. This most likely occurred because of heat expansion. Even after cooling everything down for over 6 hours, I still had to use a microfiber cloth and a pair of pliers - the worst case scenario. Luckily the ports are not broken in the switch.Just to clarify, the Ubiquiti Unifi controller showed nothing but errors for both ports. It did not matter if I turned off the switch and had everything plugged in from first turning on. One of the ports seemed to flip between being connected and disconnected.Maybe there is some compatibility issue with the 10GB module in the 1GB port, however that should make no difference seeing as most Ubiquiti SFP ports are 1GB. The slider mechanism that helps pull the module out is still completely useless on these. And the heat coming off these is way over and above what anything plugged into your network devices should be.If you are looking at these to expand the ethernet ports in your switch, this is not a reliable solution. You should be adding a second switch, and splitting your connections across to the other switch. Maybe even just use the modem/router ports if you do not need to connect to a domain.You could use the Ubiquiti SFP to SFP cable, which will actually reliably work, to connect to the second switch.I have only ever had luck using the Ubiquiti SFP modules for connecting fiber cables to Ubiquiti switches in commercial environments. Even for the home, this will only make you frustrated.These Cable Matters modules are just poorly designed.

This is a really nice RJ-45 transceiver for SFP port. Tested on TP-LINK ER7206. This allowed me to use my SFP Port for WAN port, freeing up one of the RJ-45 Port for Multi-WAN Uplink to the ISP. This option also eliminates adding an additional device of an RJ-45 to Fiber converter which also require power. It makes things simpler and easier.My only complaint / nitpick, is that it gets warm to the touch and sticks out like a sore thumb. However, performance was never affected. I don't know about its longevity, but compatibility, functionality, rated speed, and performance, this is a winner.

The Spectrum ONU that terminates my just-installed 1 Gbps symmetrical fiber service has an RJ45 port that runs only at 10Gbase-T or 1Gbase-T - nothing in between. Coincidentally so does this Cable Matters SFP+ device. If I had terminated the 75 ft. run of CAT 6 from the ONU directly on the UDW RJ45 WAN port which tops out at 2.5Gbps, the ONU would handshake down to 1Gbps and I would likely not get the full measure of bandwidth I paid for off of the ONU. I also wanted a solution that would accommodate increased subscription bandwidth over time.The UDW also has an SFP+ WAN port that runs at 10Gbps and this device works like a charm for my application. When they say it works with Ubiquiti, I can attest that it really does. Save yourself the headaches that come with taking a crap shoot on some no-name RJ45 SFP+ device that works only until Amazon's return window closes.
