Abstract
A simple implementation of a high-capacity switching matrix includes four input functional modules each having one input and four outputs and four output functional modules each having four inputs and one output. A broadcast network has 16 inputs connected to the 16 outputs of the input functional modules and 16 outputs connected to the 16 inputs of the output functional modules to broadcast four signals from each input functional module simultaneously to each output functional module. The broadcast network includes four send subsystems each sending four optical carriers at four different wavelengths .lambda..sub.1, . . . .lambda..sub.4 and four receive subsystems each receiving four optical carriers at these respective wavelengths. The broadcast network further includes four optical buses each connected to a respective input of a receive subsystem and to a respective send subsystem so that the jth bus for j=1 through 4 receives from the kth send subsystem the carriers at the wavelengths .lambda..sub.1-k(modulo 4), . . . .lambda..sub.4-k(modulo 4). Applications include switching equipment.
