I havent tested this working, but it definitely doesnt work with an intel x520-sr2 ( 82599ES ) It doesnt work with my TL-SX3008F either, despite claiming to work with TP-link devices. The transceivers that came with my intel x520 worked with the switch fine. I even bought 2 of these and tried both, when I connect them to my intel card, the driver crashes.

The long and short? It works and works great. Fast no nonsense setup. Verified 10G compatibility between the Netgear XR700 wireless router and Netgear SX10 switch networking using a 5 foot Mediabridge Cat7 Ethernet Patch Cable. Great price and great performance. Thanks Amazon.

Works well and is affordable. I have no complaints with these. Just plug it into switch or NIC and then plug your fiber into it. It also works with Intel NICs and links at 10Gbps.

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.

Bought one to test for an ODroid H2+ / Ubiquiti US-16-XG cluster deployment. After updating the drivers for the Realtek 2.5GbE NIC I was able to hit 2.3Gb in iperf3 easily. Will be purchasing more.

Had a few issues at first getting it to communicate, but I might have just been impatient/worried about the low price... Think my switch was just slow at showing it. Anyway after it connected I havent had any issues since

For those of you who have Intel x550 adapters such as the Sonnet Twin 10G (Thunderbolt 2) you may have experienced pain with consistent throughput with Marvel Based 10Gb switches like DLINK. It seems you could always sustain 7-8Gbps down, and roughly 2.5-2.8 Gbps out. I decided before I start changing network adapters or switches I would give this a try now that 10Gbase-T SFP adapters are reasonable. Well it worked, I can now sustain between 10.5 and 11.1Gb/s both directions. This matches what I get when directly connecting an Intel x550 and x540 on 10GBase-T directly attache with a 25 CAT7 cable. This is so much easier than ripping out infrastructure!!!! I have used the poleax 10gb SFP 10gb SR transceivers extensively and they have been rock solid. Sure is nice when you just plug and forget and the data keeps crunching!

Upgraded to Sonic 10G and existing CAT5e worked (approx 10 meter) with it to bring 10G connection.

Just like the title says, its not compatible with unifi stuff. I purchased 2 pairs to run fiber cable and it would not work at all. Tried everything I could, the moment I plug in official Unifi modules everything worked right away. It was plug and play with unifi modules, while these gave me a ton of trouble and still never worked properly.

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