Review: Perfect! - 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect!
*by R***G on 3 June 2023*

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.

### ⭐⭐⭐⭐⭐ veru good
*by S***I on 12 February 2024*

Good quality, packing, and timelines.

### ⭐⭐⭐ Doesn't auto-negotiate down to 10Gb as details say it can....?
*by C***S on 3 November 2025*

Got one of these in a Mellanox ConnectX-4-Lx card and it won't negotiate down to 10Gb talking to a 10gb 10Gtek module in my TP-Link 3008 - don't know why as it's supposed to be able to. Updated the card with the latest firmware (in case that was the issue) and still no joy. Gave it 3 stars as I will keep the module and when I upgrade the switch to 25Gbe I will try again then and my other 10Gtek modules have worked flawlessly so maybe it's user error?
