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

Works great between my Ubiquiti Unifi Dream Machine Pro and Unifi 24 Port POE Switch. I just had to manually set the connection speed on the UDM-Pro to 1G (Bug on Ubiquitis side).

Edit: seller updated product description to accurately describe the length very clearly. Bravo!!! I’ve only taken off one star from my misfortune but now you will be able to accurately size your cables 1 star simply because this is totally unusable! 1 ft long is from tip to tip of cable. The actual length by the time you get out of the strain reliefs is about 4 inches, which means you can make a U shaped bend that can connect devices about 3 from port to port. My original goal was to use this to connect my QNAP NAS to a network switch sitting on top of it, which is about 6 from port to port, however this cable cannot accomplish this simple task! The 2 1/2 inches that the SFP card goes into the device on each SHOULD NOT count as cable length!!!!

Quality DAC cables. If you need them then you already know what they do. These run 10GB for me with zero issues across several different NIC brands.

I set up an enterprise VMware environment at home for certification purposes as well as keeping my skills fresh and keeping my thumb on the pulse of technology. Doing so, a 10Gb network is a must and you need to source cables somewhere. Angry at myself for throwing out 60 or so of these cables at my job 2 years ago, I had to buy some.. and they arrived fast and definitely work great. The only thing to be aware of is that the pull tabs to release the cable dont all work properly. Its a well known fact that you sometimes have to push the cable in while pulling the tab to release it, but that trick doesnt work here. You have to use a paperclip to slide into the slot carefully release it. For that reason, and only that reason alone I have to take away a star.

Usually in high speed networking you dont want to use anything cheap but 10Gtek has really surprised me with their quality. I am using two of these to stack a pair of Fortinet Fortiswitches. I bought the ones for Cisco and they work fine. I have used their Gbics in a Ubiquiti POE switch and they have had no issues for over a year. These cables didnt even exist 10 years ago as the shortest you could get from Cisco were 3 meters long and at $250. They click in positively and stay put with no play. They also unclick easily and pull out without getting stuck.

UDM pro to Unifi 24 port POE switch for my usage Works perfectly No errors/dropping connection noticed No issues Great price Would recommend

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.

Works great with every piece of 10Gb equipment Ive use them on. QNAP NAS units, DLink 1510 Switch, HP Dual Port 10Gb NIC, and Connect-x2 NICs.

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.

Ive bought several 10Gtek products, and as always, this cable is made from high-quality components and is well built -- it looks and feels like the wildly more expensive competitors version. Worth every penny. Anytime I need a special cable or network connection component, Im going straight to 10Gtek.
