There are cables marked as Category 6e on the market. These are NOT the same as Category 6A cables.
Category 6e cables may perform well beyond the requirements of Category 6, but do not meet the strict alien crosstalk requirements of ANSI/TIA-568-C.2 Category 6A.
If you require 10GBASE-T support, ensure you specify cables and connectors meeting the requirements of ANSI/TIA-568-C.2 Category 6A.
