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

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.

It was delivered fast and reasonably priced. I bought a couple of these to install on my Ubiquiti Dream Machine Pro SFP ports. I hooked one up to my UDM PROs SFP WAN2 port and connected to my ATT BGW320-505 RG 5GB port using a Cat 6 patch cable. I had to tell my UDM Pro to configure in the WAN2 port at 10 GB speed as it was not initially configured out of the box. Unfortunately the UDM Pro does not currently support load balancing so I have to disable the 1GB Lan port to test it. It does do failover so I can literally pull the WAN1 patch cable and It works. However the Work in Progress is that the upload speed appears a bit slower than it did on the 1GB Lan port. I dont know if thats just the speedtest vagaries or if its a UDM problem with WAN2. I have read a few other people havingsimilar problems. So its still a WIP. Also, I do not yet have a desktop with > 1GB lan port so I cant test any over provisioning yet if I have any from ATT. Either way the Transceiver worked out of the box on my UDM Pro.

They work advertised with my Mikrotik Powerbox Pro and also with my Mikrotik Hex S. Paired with a 1Gb fiber cable.

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.

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.

10 GBit Verbindung zwischen den SFP+ Ports meiner Mellanox Karten, einem Qnap Switch und einem Qnap NAS läuft problemlos.

I purchased 2 of these and put it in to two of my machines on my network that was close together. Transfer rate for files from machine to machine is now astonishingly fast. What used to take hours now takes minutes. Great product for the price. The best part of it all is that you dont have to deal with fiber.

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

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.
