Cables

Twisted Pair Cable Types

Straight-through Cable

The majority of twisted-pair environments utilize twisted-pair

cables that are wired straight-through. This means that each pin of

the modular plug connector is wired to the same pin on the opposite

end of the cable (i.e., pin 1 is wired to pin 1, etc.) Straight-through

cables connect workstations and servers to repeaters and switches.

Cables for 100BASE-TX use two pair (pins 1, 2, 3, and 6). Cables for

100BASE-T4 use four pairs (pins 1 through 8).
