How can this be incorrect? My contractor presented me a choice of cables, one was AWG 23 (labelled CAT.7) and one was AWG 22 (labelled CAT.7A). I chose the AWG 22 cable because larger diameter means less heat dissipation. I made this choice because I want to install PoE+ devices on some of the outlets connected with this cable. The Keystones terminating the Cables will be CAT.6A anyway.That is factually incorrect.
I will probably try using 10GBase-T at some point, but most devices will be 1GBase-T.
