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

These work between a Ubiquiti X16 10Gb switch and various adapters. Including the FreeNAS expansion cards and Dell cards that came with several of our servers. No problems so far.

Great cables

Works perfectly but the connector protection does make it difficult to close the door to a standard rack without it being bent. I’d worry about attenuation and durability long term if it was in a rack that is frequently opened and closed

I am very happy that I bought these cables.

You could spend a ton of money on a name-brand version of this cable, but theres really no need. I was surprised at the high quality and superior construction of this cable at such a low price. Its working perfectly, and Im confident itll stay working for years.

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

Perfect 10Gb interconnect between my two switches.

The Dream Machine Pro has two SFP+ 10Gbs ports I used them to uplink an old Ubiquiti US-24 Unifi Switch using one of the two native SFP ports, but also to uplink a newer Switch Pro 24 PoE that has 2x SFP+ 10Gbs ports. These cables allowed the auto-negotiation to work fine for each of the switches. I didnt have to fiddle with anything, other than re-classifying the UDM SFP+ WAN port to be just another LAN port. All is great right now.

This works on freenas and mikrotik switches like a charm 10gig fun

No difference in speed from the original Cisco part.
