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).
