I have used several of these in ubiquity equipment and they have worked great. No problems.

I purchased 2 of these, and theyre both reporting as SFP-10G-SR fiber transceivers instead of RJ45. As a result, the other end wont negotiate higher than 1GbE. Unless I can figure out how to resolve this, these are going back. Hopefully support can assist, if I can figure out a way to contact them.

Works as expected in my Cisco C2900XL switch

Thanks for the item

Purchased to connect my Google Fiber to my Ubiquiti UDM Pro to achieve 2Gbps down / 1Gbps up. I was able to get 2 down but up was limited to 380 Mbps. I replaced it with an SFP+ to Rj45 module from Ubiquiti and reached the full 1Gbps up. Obviously, this product is not truly compatible with Ubiquiti as advertised.

Worked ok for about 2 weeks, packets dropping here and there then suddenly without warning 1 of these failed out of nowhere. WIll need to go with something else if failed that quickly.

These work great and I will get more when needed.

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.

Work fine in my 3750, no issues and no IOS complaints.

Wanted to write a review because its not entirely clear: this transceiver supports 2.5gbe and 10gbe links according to my network testing (I didnt test 5gbe). Its a little bit funky if you look at the description and it says 10gbe only but thats because the transceiver only advertises itself as 10gbe fiber to the host network card but it will negotiate 1/2.5/10 links over regular RJ45 copper. I verified the network speeds with iperf3.
