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)

Works between rack switch and external QNap NAS

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! ;-)

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 needed two new SFP+ cables for some new equipment in my server rack and these were exactly the size I needed and they work with Ubiquiti switches I have and they worked great and the length was so I did not have to hide the excess cables. I have used 10Gtek DAC cables before and they have never failed me.

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!

Super bien funciona perfectamente y la compatibilidad es muy buena, funciona con Ubiquiti y conexión a tarjetas sfp+ Intel

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

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