Control system for an optical fiber switch

摘要: An optical switching fabric enables an signal entering the device on any one of multiple input ports to be directed output ports. Light port is reflected by individual mirrors or more mirror arrays port. Methods controlling fabrics compensate for distortions due mechanical and environmental changes without need measure losses along all paths linking Reference are interspersed among reference Periodically, positions which maximize intensity light deflected from ports, measured. The measured used predict
