10G SFP+ RJ45 Copper Transceiver, 10GBase-T RJ-45 SFP+ Module, up to 80 Meters, for Cisco, Ubiquiti UniFi, Mikrotik, Fortinet, Netgear, D-Link, Supermicro, TP-Link (CAT.6a/CAT7)

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 don't 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 can't test any over provisioning yet if I have any from ATT.Either way the Transceiver worked out of the box on my UDM Pro.

Echoing a similar review for these transceivers, they are BAD. They don't come close to their advertised 10gbps speeds. I was barely able to achieve 1gbps and over 30 mins they units seem to degrade in performance.I was using a direct connection to the NAS over a Cat6A cable, that was less than 10 feet long. This should have been an easy cake walk and instead it was a huge failure.

Worked very well with my Ubiquiti ES-16-XG switch and an iMac Pro 2017 (builtin ethernet port) - I can get sustained 10Gbps with iperf3, and no connection drops, over 120ft of CAT7 STP with two keystone connectors in the way. (trying the same over CAT6A UTP, however, saw a permanent connection drop after about a minute of being connected)

Used for 2.5g networking (should be a lighter load on the adapter I would think) Anyway the link worked fine out of the box but as soon as the device heated up (about an hour later or so) I was getting 200mbps instead of 2.5gbps. This was consistent across multiple ports on my 10g SFP+ switch and with several different cables (cat 5e, 6a and cat 7). I think this product can produce its advertised speeds only for a short while just after plugged in. Be careful and do thorough testing if you buy this. I'm returning mine.

Ubiquiti, TP-Link, Cisco, FortinetNot a single one worked. I never got around to using them, I just wanted them on hand. What a rip off. We bought some other ones for 1/4 of the price that worked with all of the above. Ridiculous.
