Abstract

A switch module, for use in an optoelectronic switch, has: a client portion for connecting to an input device or an output device;a first fabric portion and a second fabric portion, each for processing signals and communicating with other switch modules, the first fabric portion having a transmission side and a receiving side,the transmission side having: a transmission side input for receiving a first electronic signal carrying information including information about a destination switch module of the first electronic signal, the first electronic signal received from either: an output of the second fabric portion, or an input device, via the client portion;a transmission side conversion means for converting said first electronic signal into a first plurality of optical signals containing the same information;a transmission side multiplexer for converting the first plurality of optical signals into a multiplexed fabric output signal for transmission to an active switch, and the receiving side having: a receiving side demultiplexer for receiving a multiplexed fabric input signal from an active switch and separating said multiplexed fabric input signal into a second plurality of optical signals;a receiving side conversion means for converting the second plurality of optical signals into a second electronic signal, anda receiving side output for sending the second electronic signal to either: a transmission side input of the second fabric portion, or an output device, via the client portion.
