Q: When should I use Catgory 6A?

A: Category 6 cabling is the current workhorse for Ethernet environments and will satisfy most cable to the workstation requirements including data rates found in currently installed Power over Ethernet applications in use today.

1 gigabit Ethernet applications use all four pairs for bidirectional transmit and receive each pair transmitting 250 Mbps (megabits per second) times (x) 4 pairs to provide a total of 1 Gbps (gigabit per second). Due to the 0.5V signal encoding separation, the inherent noise-cancelling effect of balance twisted pair cabling works well against electrical interference found in most commercial environments. There is no cable to cable interference, also known as alien crosstalk, performance requirements for Category 6 which limits its use to 1 gigabit Ethernet and below.
