Optical switch, optical matrix switch system and method of optimizing system connectivity.

摘要

Optical paths to propagate a plurality of optical information signals intersect optical paths to transmit lights to a plurality of subscribers. Light power dividing and propagation direction changing device (20) to separate the requested optical information signals are arranged at the intersecting points. Losses of the optical information signals due to the separation are compensated by optical amplification, so that the signals can be distributed to all of the subscribers while keeping a predetermined intensity. Thus, the same photosignal can be distributed to a plurality of subscribers. The system can be easily expanded in correspondence to an increase in number of optical information signals and an increase in number of subscribers. <IMAGE>
