Review on High-Performance Ethernet Cable for Efficient Network Patching, Industrial Electrical Wiring, and Seamless Internet Connectivity by Tim Paolucci

It took me a few days to figure out why I wasn't getting 10Gb/s on my new ethernet installation cable for so long. I have 10GB in one direction and only 1GB in the other. The worst thing was that there was only 200 Mbit/s one way. But a really hard problem to solve because when I switch to 5G or 1G mode on the Switch side, it worked. So I figured the problem was a reinstall of a long ethernet cable. Then maybe I thought about my server that I used for the test. I then thought maybe my switch, 10G adapter. It never occurred to me that the problem actually lies with this short connecting cable. If you need gigabit that's probably fine, but then it's category 5e. If you're willing to take the risk for 10G, that's okay too. This might work if the entire path is short enough, but when you need to debug, it might not be easy to come to the conclusion that this small snippet is a mystery and produces a strange result. I was about to ask the installer to redo his job, which would have cost me very little.
