I always wondered why they use 4 pair cable. My understanding is a pair
is used each direction. Can you use 2 pair cable? Does 2 pair cat 5
cable exist?


CAT 5 only describes the performance characteristics of the cable. It
has nothing to do with how many pairs are in the cable. And using all
pairs of 4 pair cable is not unusual in computer work with GigE being
the most common current example.
