3m/9.8ft SFP+ 10G DAC Twinax Cable for Cisco SFP-H10GB-CU0.5M, Ubiquiti, Netgear, Mikrotik, Supermicro | Passive | Length Options: 0.5m-7m

I've been using this cable for a while, and I have to say I have no issues with it. It's more of a throughput cable, and I haven't noticed anything bad with it; speed seems to be fine. It's a ready-made cable, plug and play. My switch picked it up and set up instantly.

Item as described and works perfectly for my QNAP NAS into my 10G switch

Anyone in the UK knows that Ronseal does exactly what it says on the tin - and this cable is no different. Plugged into my Synology NAS with a 10gb network card and into a switch with the same - configured the NAS to use the plugged in card and voila - network traffic working easily via the cable.Now if only I could change everything to 2.5-10gb I'd be a happy bunny, but that's a work in progress :)

Good compatibility with Mikrotik switches. Unfortunately I had 2 of these fail early - they stopped establishing a link. 2 were also prone to sticking in the SFP+ port and difficult to remove (the plastic pull would not work effectively and some care was needed to remove the DAC).

Great, cheaper alternative to fibre. Cheap, and I've tested it with every type of 10gb Switch. This will be the main cable I use from now on. At first, I was spending a lot more on fibre. Because the run is at most 5 meters, I can get full 10gb Speeds with this DAC Cable

I used this to connect a Unifi switch and a server with a mellanox card. It worked straight away.It was delivered more quickly than I expected.

Another well packaged professional DAC cable ...great price

TLDR: 7m cables did not work for me but 3M did - Dell servers, intel nic , unifi , pfsense.I bought 6 x 7m cables after using 3m ones between my pfsense firewall and my unifi networking gear. I got them all changed over and the next day i noticed everything on the network had issues, Because i moved all the networking kit and server kit i have done 2 full days of testing between multiple servers, patching , firmware updates you name it. I then numbered all the cables, tested between servers, subnets, viewing switch data, swapped out working cables and pcie cards to other hosts, booting different host configuration. Came to realise its the new 7m cables behaving oddly. I chucked two x 3m ones in and the results between them hosts were perfect, changed a third cable results perfect and now i'm running on different or shorter version cables the network is rock solid and the servers that can saturate 10gb are now doing it again. I am now processing a return, rating as 1 star as i believe the 7m ones to be faulty with too many different variables following the cable.
