•Shielded (STP) or unshielded (UTP)
•Pins 1&2 and 3&6 are the two active pairs in an Ethernet network.
•All four pairs are used in a gigabit Ethernet network.
•Use only dedicated wire pairs for the active pins:
(e.g., blue/white & white/blue, orange/white & white/orange, etc.)
• Do not use flat or silver satin wire.
