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.

Very impressed by this cable. Using it between HPE Emulex flex cards and a Ubiquity USW48pro poe switch and this fully specs out full 10gbps full duplex with zero issues or loss. Very solid sfp+ housing, with a perfect slide fit with reassuring engagement. Disengagement is fine without any bind. But unlike most, the cable jacket, wire comp, and 24aug make this stout and reassuring with surprising quality. Never heard of this cable maker, but now am a solid fan.

Works with QNAP controller as well

This DAC cable worked as advertised, I’m getting 10Gbps with no issues. It’s a solid cable and I really like how easy it is to remove from an SFP+ port. I will most likely buy again if I ever need more.

works as expected between my switch using Mellanox and HPE sfp 10gbe nics in my home lab. 10gbe made a big difference in the iscsi storage for my VMware environment, vms are more responsive.

Worked great for Intel x520 NIC. Came right up.

I have no idea what the lifespan is on some of this stuff, but 4 years is not it! Still going strong.

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

Cheaper and functional solution to a SFP+ Transceiver / cat 7 cable, with the added bonus of lower power comsumption. This cable is used to connect a PC workstation with a 10Gtek X520-10G-1S NIC (Intel 82599 chipset) to a Netgear MS510TX switch. The solution works and have a reliable 10 Gb/s network link.

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