10Gtek[Green Colored 10G SFP+ DAC Cable - Twinax SFP Cable for Ubiquiti UniFi Devices, 0.3-Meter(1ft)

I have been using this for a few weeks now and no issues. I added photo showing UDM controller recognizes connection at 10gb. I haven't been able to saturate the connection for any long term instances to see if speeds stay consistent at 10gb, but the transfers do do hit it so there isn't any reason they can't stay at that.

Thin flexible, works perfectly with Brocade and Tp-Link.

Ubiquiti Dream Machine to Ubiquiti 24 Port POE switch

Have several DAC cables now from this company and every one has functioned without error. Will continue buying from them as long as the quality remains high and they have things I need

What more can I say, it’s just plug and play. Never had an issue with these, nice to have the option of choosing a color.

No issues with 2.5G between Mikrotik L009 (SFP) and Mikrotik RB5009 (SFP+). Need to manually set negotiation to 2.5-BaseX

Hi Unifi users - this is my third attempt to find a cable that works between the UDM and a Yuanley switch - this one fits the bill! Negotiated 10gig connection from the 16 port switch with no issue, allowing 2.5 gig from the Yuanley switch ports.The only issue is the cable is 1 foot from tip to tip on the SFPs. So, not much room to spare in the rack. I may upgrade to the .5m length later, and definitely buying a 1m for a switch a couple U's farther down.But it works, so we're rounding up!

I originally bought this to connect a UniFi NVR to a UniFi Dream Machine Pro SE. When I did the initial connection I was disappointed, as it auto-negotiated at 1 gbps speeds despite both being capable of 10 gbps. When I set the port manually to 10 gbps it took, and worked just fine.More recently, I changed my setup to consist of a UniFi 48-port Pro Max switch. My Dream Machine is connected to it via SFP+ (using a UniFi DAC cable) and the UNVR is connected to it via the GTek DAC cable that I used before. Again, it auto-negotiated to 1 gbps speeds. This time around, though, forcing 10 gbps causes the connection to drop. I tried unplugging and re-plugging the cables, to no avail. I'll replace it with a UniFi-branded cable when the right length comes back into stock.I like that the GTek cables come in a nice variety of colors and lengths. It just seems that compatibility is a mixed bag for the newer devices.Build quality seems fine, but it's also worth noting that these cables are a lot more difficult to unplug compared with the UniFi cables. The plastic tabs also seem a bit less durable; they're harder to grasp, so I put a small pen into the circle and pull that way. It works well, but one cable was so tight in there that I worried the plastic would snap. (It warped a bit, but held.)Prior to the switch issue, I would have whole-heartedly recommended these. Now, I guess I'd say there's a possible compatibility risk.Edit 3/30/2024: Replaced the 10Gtek cable with a UniFi-branded DAC cable and the UniFi NVR and switch immediately negotiated at 10 gbps, no problem. The compatibility issue seems to be with the cable.That said, it doesn't seem like the cable simply doesn't work with the UniFi Pro Max switch line. I added an Intel X520-DA2 two-port SFP+ card to my Synology DS1621+ and connected it to my UniFi Pro Max through a SFP+ port, using the 10Gtek cable. It immediately negotiated at 10 gbps and remains stably connected. Maybe there was just an issue between the NVR and Pro Max switch, or maybe there's just something about my two devices in particular... if you need the color or cable length then the Gtek cables are probably fine, and I'd certainly consider trying another one in the future. If you don't have the time to deal with a cable compatibility issue, though, UniFi users are probably better served sticking with the Ubiquiti cables to ensure compatibility.
