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

Love 10GTek products. I used it to connect two Unifi switches. Reliable. Highly recommended.

Works perfectly fine between an old USW-48-500W and a UDM SE. Comes right up at 10GE. Not that I'm going to see that, as I only have a 1G Comcast connection, that breaks through the 800mbps barrier on a perfect day. The .3m length is perfect for the two devices mounted on top of each other in 2U of space. It would be very tight, and might not work, if there was a U of separation between them.

Good quality cable and a great selection of lengths and colors. Great to have exactly the right cable in your rack.

Works as it should. My application is interlinking UniFi switches and a UDM.

Excellent quality DAC cable for the price. I have these working with my MokerLink 8 port 10G SFP switch and Intel X500 series based Fiber cards. I speed tested and bulk transfer tested these and everything seems to work up to very close to the 10G PHY they advertise.

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.

Connecting my Netgear 10g switch to my UXG Fiber gateway. Good stuff.

Excelente producto lástima que compré dos y lo resolví en dos envío y arg tiene solo 5 envío al año !!

Just what I needed. Good quality cable!
