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)

Ive been using these for a while. Im using a few of these of various lengths to join multiple switches and give a good connection between certain servers. Its running very well.

I use this DAC cable to connect to TP-Link Omada switches. I preferred to use the DAC cable, so I can utilize all the RJ45 ports on the POE switch that I have.

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.

I bought a pair of these to connect my Ubiquiti 48-port Gig switch to a new Netgear XS716T 10GbE switch. The Ubiquiti switch has two SFP+ ports as does the Netgear switch. I connect the two switches with the 10Gtek cables and within seconds the switches were connected at 10GbE full duplex. No issues at all. Very nice quality cables.

These DAC cables worked like a champ in my rack. I’ve used them before on odd jobs, and have only had an issue with certain devices that’ll negotiate but not pass traffic until you force 1Gbps (if incapable of 10Gbps). Build quality, reliability, and performance are second to none with these devices, and the price cannot be beat!

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

Works between rack switch and external QNap NAS

Getting a full 20gbps connection with 2 of these bonded on Unifi Switches.

Took some finagling, the Ubiquiti products are finicky. For some reason this only negotiated 1 Gbps at first, but when I ran 2 and aggregated the ports I got the full 20Gbps. Who knows what happened or why, but in the end it worked

Works perfectly
