Abstract
An optical signal switching device comprises a plurality of broadcast couplers (), a plurality of wavelength selective modules (), and optical connection means linking outputs of broadcast couplers to inputs of wavelength selective modules in order to route incoming optical signals received by said broadcast couplers to said wavelength selective modules. The wavelength selective modules are arranged in a plurality of groups (), the wavelength selective modules of one group being connected at the output to a common neighboring node. The optical connection means () are configured in such a way as to enable, for each of said broadcast couplers, the broadcasting of the incoming optical signal received by said coupler to at least one wavelength selective module of each group simultaneously.
