10Gtek# SFP+ DAC Twinax Cable, Passive, Compatible with Cisco SFP-H10GB-CU2M, Ubiquiti UniFi, Fortinet and More, 2 Meter(6.5ft) | 0.25-7m Optional

Does everything its supposed to. 10G speeds between 2 Mellanox SFP+ cards. Quality is up there with the best DAC cables, and i have no questions this cable will last for a very very long time.

Superb product, cheap and works with all sorts of devices (UBNT -> Mikrotik -> Cisco -> Zyxel). I will buy again (and I dont think the color matters too much).

I used these cables to connect several HP DL380 Gen9 and Gen10 servers to a Cisco 4500 X switch. Everything works fine and no problems have occurred so far.

I get the speeds advertised! plugged em in ~5 days ago and been working since, the fact that Im writing this review can attest that it works 0 problems

Was having problems with separate cables + transceivers (most likely the cable) - and when I switched to this integrated fiber SFP+ - xfers immediately jumped to expected levels.

Worked on my ubiquiti switches flawlessly. No issues in 2 months so far.

Work as expected - hooked these up between a dell powerconnect and tplink jetstream (2x 10G uplinks) - works!

Expensive cable, but it does the trick. Seems to be quite durable given that I accidentally installed it improperly when I first got it. I also accidentally crushed it with the server (weighing about 100 pounds) but the cable still works perfectly!

Works great with Solarflare and Intel 10g adapters. No issues with Cisco/Extreme/Mikrotic switches either.

Works perfectly with Ubiquiti UniFi network switches and appliances. I use this DAC cable to connect a UDM Pro to a UniFi Enterprise-POE-24 switch and it works flawlessly at 10gb. I also used this DAC to connect my UDM Pro to a UniFi 24-port-POE switch at 1gb without issue. Cable is made with quality and feels durable.
