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

plug and play. works as intended. link, link, aggregate. up comes the 20 Gig connection. If you think that youll like one, grab a second.

I bought Mellanox switches (and cables) and wanted to connect our Cisco Catalyst 3750-X stack (12.5X firmware) using the C3KX-NM-10G modules. The Mellanox cables would not work and a Cisco TAC case told me to try a different type of cable. We tried the undocumented commands to disable HCL checks on the transceivers but it was still failing. I found these and ordered 4 to test. The part number I searched for and ordered (SFP-H10GB-CU3M) was not the same as what was on the items shipped, but I assumed they were compatible so I tried it. Worked perfectly.

I successfully connected a UDM Pro with SFP+ to a UniFi USW-24-POE with SFP using this cable. I had to manually force 1Gbps FDX on my UDM Pro for it to work.

Easy to use and install. Priced right.

So far the cables have worked great. Id highly recommend them.

I really like 10Gtech brand lately. First choice when available. Great pricing, though increasing lately.

This DAC cable is well built and works perfectly with my Solarflare SFN7122F and Intel X520-DA2. My OEM Intel X520-DA2 doesnt accept non-Intel SFP+ but this cable works perfectly. Testing throughput with iperf3 gives me 9.9Gbps (MTU set to 9000) and I couldnt be happier with the result. This is my 1st 10GTek purchase and I will definitely consider their products moving forward.

Connected my D-Link DGS-1210-10P just fine (1 Gb/s Full Duplex, that is the max for the port).

These cables have worked perfectly with our Unifi switches.

It works exactly as expected. There is nothing else to say.
