Review on InstallerParts CAT6 Ethernet Cable - Red, 0.5FT, 10Gbps, 550MHz - Professional Series for High-Speed Internet by Major Callaham

I don't know why "training" is rated for this cable, but if your training depends on transferring data from one port to another, this is your cable. Painting. It has a pinch protection, it's a standard board. I hooked it up to my Raspberry Pi 4 and felt it tremble with joy. The Switch was less than impressed with the experience, but switched data over the cable and back with its callous dead inner expression that said it was just doing it for the money, like most switches.
