光ファイバ - スイッチ、マルチプレクサ、デマルチプレクサ

Fiber optic switches, multiplexers and demultiplexers block or route optical signals in a fiber optic network. Where switches simply block or pass optical signals on individual or multiple channels, multiplexers route multiple channels out to a single fiber optic cable. Demultiplexers route a single channel out to multiple fiber optic cables.
