Abstract:
1. An optical signal processing device comprising supply means adapted to deliver optical signals, first multiplexing means adapted to deliver to at least one primary port a multiplex of channels corresponding to chosen bands, on the basis of optical signals received at secondary ports, and optical routing means adapted to route said optical signals delivered by said supply means selectively to secondary ports of said first multiplexing means, as a function of instructions received, in which device said supply means comprise a multiplicity of sources each adapted to deliver substantially simultaneously optical signals having the same modulation and carried by different wavelengths, and each secondary port of said first multiplexing means comprises selective spectral filtering means adapted to pass only an associated portion of the wavelengths of the optical signals delivered by said supply means, said portion belonging to one of the bands corresponding to one of the channels of said multiplex, and the wavelengths delivered by one source cover several wavebands associated with several secondary ports of the first multiplexing means.
