Abstract
An optical switching device is provided. The device includes an input stage () comprising broadcast modules (MD-MD) that provide duplicates of the same multiplex, an output stage () comprising programmable multiplexer modules (OWS-OWS) having inputs associated with respective broadcast modules, and an intermediate stage () connecting each programmable multiplexer module input that is associated with a broadcast module to an output of the associated broadcast module. Each broadcast module includes a programmable demultiplexer module (IWS-IWS) having a transit output (B), and a selection output (B) and a star coupler (SC-SC). The transit output (B) is connected to a first input (C) of the coupler and an input and an output of a processing device (RG, RG') are respectively connected to a selection output (B) and to a second input (C) of the coupler.
