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

Very good adapter stuck on a Mikrotik router. No issue to report whatsoever.

Literally a plug and play on my Cisco C1300. I just plugged it in and and did its job without delay. I got a used one from amazon resell for less than £14, good value for money. Quality looks good and sturdy to me.

Does the job, gives additional ports.

So far very happy with this..... Successfully used with a Netgear GS110TPv3 and, although it only reports 1000Mbps status in the GUI, it has been shown to work with 1000, 100 and 10Mbps links which was one of the main requirements of this purchase..... unlike others which only seem to support 1000Mbps.

Received 4 of these today and installed them in my Mikrotik CRS317-1G-16S. None of leds lit up, after going round and round in the settings I eventually tried turning off auto negotiation for all ports where these SFPs were installed Set them to use 1000 Mbps and the ACT led lit up and all devices appeared on the network

Cheap SFP for mid range Ethernet speeds. Needed this for a 2.5Gbps switch which for some reason struggled to support 10/100Mbps port negotiation. Good purchase.

Needed this for a unifi dream machine pro for backup wan. Inserted and worked first time. Well boxed and quick delivery. Excellent.

I purchased one of these a few month ago for my UDM Pro and it works great for my WAN 2 failover, I purchased one last week for my client and couldn't get it to work in their UDM Pro in fact it seemed to interfere causing problems with the whole network? when I removed it all was OK, I took it home to test in my UDM Pro and no light, It just wouldn't show up no matter what I tried. I sent it back to amazon and purchased another, this one seems to have the exact same problem, even if i manually set the negation speed i get nothing, I put my one back in and all works fine. as you can see in the photo the bottom one is my original which works and has the same model number, the only difference I can see is the print which looks a slight different font. Something must have changed in these adapters? either they are not compatible with the dream machine pro or I have extremely bad luck and received two faulty adapters, either way I am returning for a refund and will not be wasting anymore time purchasing another of this brand... shame as first one worked first time.
