SFP+ DAC Twinax Cable, Passive, Compatible with Ubiquiti UniFi ES-48/ES-16-XG/USW-Pro-24-POE/USW-Pro-48-POE/US‑16‑XG/US‑48, 0.3 Meter(1ft)

Did the job. For anyone wondering, I used the Ubiquiti DAC to connect a MikroTik CCR1009 to an UniFi US-16-XG. Link came up at 10Gbps with no issues.

Ive had no issues since with the 1.5m DAC in the three months since purchasing it. Works fine at an excellent price!

If youre looking to link up a couple of mix-speed DAC port Ubiquiti appliances, look no further. This is your connector! Lots of what I read said this wouldnt work but, given the price, I thought it would be worth a shot. So glad I did because it works flawlessly. You can go into the UDM Pro settings and set the port to 1Gbe instead of the default which is auto negotiate. Having done that, this thing worked flawlessly as expected. It does so at a fraction of the price of other cables that are made for 1Gbe ports. The bonus is that if Ubiquiti ever comes out with an update to this appliance, Im set with the proper DAC already. Great buy and not only frees up a couple of network ports but also impresses all of the babes! ;-)
