CA 2340148
An optical switch for routing optical signals is disclosed. The optical switch has an optical signal path for routing said optical signals between at least a first port and at least a second port, wherein said optical signal path is divided into two portions with one portion being defined by at least two switch expansion modules; and the other portion being defined by a distribution backplane for operatively connecting the switch expansion modules together. An optical switching network is also disclosed having optical signal paths which intersect in at least two switch nodes, the network having at least two switches for switching optical signals, wherein one of the switches is located at each of the switch nodes and each of the switches includes at least two switch expansion modules and an optical backplane for connecting the switch expansion modules together. The switch modules from each of the switches are configured to permit the switch modules from either switch to be used interchangeably to complete optical switching in the other.
