An optical switching system, wherein the input channels carrying packetized data are switched one-by-one at high bit rate to output channels through an optical switching network. The packets of a generic input channel are time compressed, converted into optical signals and, at suitable instants, sent...http://www.google.de/patents/US4845702?utm_source=gb-gplus-sharePatent US4845702 - Optical telecommunication package switching system using asynchronous techniques
