Great Product!

Just got these in and tested them Feb 16, 2026. So far, so good. Linked at 10Gb between 2 UniFi Dream Machine SE SFP+ ports (on the same router). No errors logged. Will test to a UniFi 24-port HD PoE SFP+ port when those switches become available; and intend to update this review.

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.
