10G SFP+ DAC

I now have 10 or more of these cables and I have been using them for well over a year now. zero failures. I get 100% the advertised speed, As in the exact specified speed. I never get packet drops, losses, disconnects, crashes, nothing. I run 2x cables per system 100% happy. I needed more and I had to go look through my purchase history to see which brand I got as they were such a good deal. The brands I was supposed to buy were significantly higher price and I get a dead flat 10Gbps transfer per cable! And the latency is absolutely fantastic. I use this with a Microtik switch and mellanox network cards. And I have never had a single issue. The release mechanism takes a second to learn but has such a satisfying click and release feel / sound even.

Simple install, just plug it in and it works. I've always had great results with 10Gtek. 0.25m is the perfect size for linking ports for direct stacked rack equipment (no space between). Using with a UDM pro Max and a Unifi switch.

3+ months later this is working flawlessly between a Mikrotik router and Chinese switch, passing my WiFi7 AP traffic. Runs cool, fits into the SPF slots without issue. Very power efficient, measured by my Kilawatt meter.

Great product and support.Quality is excellent, worked without any issues right out of the box.Had an issue with a 10gig card and 10Gtek replied to my email in 36 hours. Had my network up and running at full speed in no time.I will be a 10Gtek user for life.

Seems to b of decent build quality. A little thinner than Cisco-branded DACs, but a bit more flexible. Didn't test throughput extensively, but no complaints moving large amounts of data between devices. Can confim it works perfectly fine on 10G SFP+ ports on several Cisco devices, as well as a Mellanox 10/25G NIC. The fact you can order these at a multitude of lengths, and significantly cheaper--unless there's compatibility issues with certain equipment, or you have a service agreement that forbids it, I don't see a caveat.

Works well to connect unifi dream machine SE to unifi 24 port poe switch.Wish I realized my switch only had a 1gbit port as the UDR SE has a 10 gbit port, but that is not a flaw in the cable. The cable works instantly at 1gbit between the pairs, and I have no doubt it will work at 10gbit as well if I had the means to test it.

I used this to connect my Mokerlink 10GbE PoE switch to my router, a Banana Pi BPI-R4 running OpenWRT. Since the orientation of these units are close enough for this short cable (.25M), it was a clean install, but it is a very short cable. If I was to do it over, I'd get the next length up to have a little more flexibility. Installation was easy and the cable fit perfectly and has zero dropped packets. I would definitely buy again.

Works fine with Meraki switches but I needed it for Ubiquiti aggregation to access and it refuses to link at 10gig. It'll link fine 1GBPS but of you try to force 10gig the link just straight up drops altogether. Probably just going to buy the ubiquiti one and use this elsewhere with another brand but figured I'd post for others to be awareof. Build quality is outstanding, sad I won't get to use it in the install it was intended for.
