Duplex cable

A duplex cable consists of two separately buffered fibers, joined together into one fiber optic cable.  A duplex cable resembles two simplex cables fused together along their length, like a lamp wire. Duplex cable ends may be distributed and terminated separately, or they might be connectorized with one duplex connector, such as the MT-RJ.  Duplex cables are most useful as a two-way communication channel, such as a transmit/receive pair running to a computer.
