Very affordable, worked with Solarflare on-load NIC, and is stable for months of runtime now.

Beware before purchase!Initially I ordered 2 and they seem to work fine until I start to notice performance issues. It took me some time to trace the issue down to an incompatibility between these transceivers and Ubiquiti switches. I ordered 4 more which all show the same major performance issues (down to ~ 30 Mbps under some circumstances. I have tried several other brands including Ubiquiti transceivers and they all work fine. None of these 10GTek work without a problem. I mailed support via their website, They boast good technical support but I never got a reply. I can return 4, but the first order I can no longer return and there is no support. Think twice! Pay a little more.

I purchased these 7 months ago and they were connected with about 75 meters of single mode fiber, and they have degraded to the point of only passing about 200 megabits. I believe they would be ok if I had used attenuators.

I was really hoping that this would be the part I needed but unfortunately it was not. I am sure there is a nuanced communication issue here but for the life of me I can't find what is the sticking point. My use case was to create a link between my router (mikrotik ccr2204) and the rest of my switch stack. I was not able to get any communication over this line even with other 10gtek receivers (40g and 100g) and all my attempts to get support from 10gtek were met with radio silence.This is a shame as I have had great luck with other parts (dac's, 40g, etc) but this one needs something but I just could not figure it out.

This is a review of the 10Gtek 25GBase-SR (100m) SFP28 transceiver. Intel-coded version. Part #: AZS85-S28-M1. It comes in a 10Gtek-branded metal container, safely padded.I originally bought one Intel-coded unit to use with my Intel 810XXV SFP28 nic. Having also tried it on my Ubiquiti usw-pro-aggregation switch, it works over there too! No need to pay for expensive Ubiquiti SFP28 transceivers! At $20 each, they're a great value over their competitors at $40-50 each.Be sure to upgrade the firmware on both the switch and the NIC. Otherwise, the link may not establish at 25G speeds. For the Ubiquiti switch, I'm on 6.5.59. For the Intel 810XXV nic, I'm on NVM 4.20.

Works without any fuss with my QNAP 25Gb switches / NICs (I believe these are rebranded Mellanox units, or at least using Mellanox chips). I have been purchasing 10Gtek optics and DACS for some time, in 1G/10G and 25G variants and they have always been excellent. I would recommend them to anyone.

Fait tres bien le boulot, faut juste faire attention, il n'est pas multi vitesse: certains modules sont compatibles 10Gb et 25Gb, celui la est uniquement compatible 25Gb.

I've generally had success with 10GTek SFP modules in my Ubiquiti gear, but this one is an exception. I bought 2 of these SFP28 modules, and both have issues in my USW-Pro-Aggregation on FW version 6.2.14. They will link up, but the initial link takes minutes, and then the link will go down every few minutes and renegotiate.I bought some Fiber Mall SFP28 modules, which work flawlessly. When I use a Fiber Mall SFP28 in my Ubiquiti switch, and one of these 10GTek modules in my Mellanox ConnectX-4 Lx NIC, the connection between them is stable.I'm only deducting one star since this may be an isolated incompatibility.
