1100 x 1100-port MEMS-based Optical Crossconnect with 4 dB Maximum Loss
01 November 2003
We present a Micro-Electromechanical Systems (MEMS) based beam steering optical crossconnect switch with port count exceeding 1100 ports, featuring mean fiber-to-fiber insertion loss of 2.1 dB, and a maximum insertion loss of 4.0 dB across all possible connections. The challenge of efficient measurement and optimization of all possible connections was met by an automated testing facility. The resulting connections feature optical loss stability of better than 0.2 dB over days, without any feedback control under normal laboratory conditions.
