10Gtek 10G SFP+ DAC Cable - 10GBASE-CU Passive Direct Attach Copper Twinax SFP Cable for Cisco SFP-H10GB-CU0.5M, Ubiquiti, D-link, Supermicro, Netgear, Mikrotik, ZTE Devices, 0.5m

Great Product!

Seems to b of decent build quality. A little thinner than Cisco-branded DACs, but a bit more flexible. Didn't test throughput extensively, but no complaints moving large amounts of data between devices. Can confim it works perfectly fine on 10G SFP+ ports on several Cisco devices, as well as a Mellanox 10/25G NIC. The fact you can order these at a multitude of lengths, and significantly cheaper--unless there's compatibility issues with certain equipment, or you have a service agreement that forbids it, I don't see a caveat.

Works very well with Cisco switch and UCS mini chassis.

Using with unifi dream machine se and older generation 24 port unifi Poe switch. Works as expected.

Bought several of these to connect Ubiquiti switches to each other, as well as servers to the switches. No issues observed after nearly a year of usage; for the price - cant go wrong with these DACs!
