<p>An optical switching system, wherein the input channels (I) carrying packetized data are switched one by one at high bit rate to output channels (O) through an optical switching network (RC). The packets of a generic input channel are time compressed, converted into optical signals and, at suitable instants, sent to an optical switching network to be switched to the desired output channel, they are then reconverted into electrical signals and expanded to their original duration. A centralized processor (EL) controls the channel switching through the switching network by means of a driving circuit (LC).</p> |
