OPTICAL CROSS CONNECT SWITCH USING AN ABSOLUTE POSITION ENCODER

摘要

An optical fiber cross-connect switch incorporates an absolute position encoder and a magnetic actuation system. The magnetic actuation system comprises magnetically polarizable actuator branches positioned surrounding the fiber and a magnetizable disk circumferentially attached to the fiber end. Selective magnetic polarization of the actuator branches moves the fiber end. A two-dimensional Moiré type position encoder determines the absolute position of the fiber end.
