be used with Cat-5e cable . Because all 1000BASE-T (gigabit Ethernet) equipment and nearly all new 10BASE-T and 100BASE-TX equipment supports automatic crossover (auto-MDIX), Cat-6 crossover cables are rare. Crossover cables are needed only between 10/100 Mb/s hosts or switches where some endpoint does not support auto-MDIX; otherwise Cat-5 is sufficient
