ABSTRACT:
A combined wavelength router and switch apparatus for use in an optical communication system is disclosed. The apparatus includes arrays of optical signal demultiplexers, wavelength division switches, space division switches and multiplexers, arranged in a manner that can increase the connectivity of an optical system using wavelength division multiplexed (WDM) signals. In several embodiments, time-multiplexed wavelength division switches and time-multiplexed space division switches may be used to increase further the degree of connectivity of the system or to reduce the number of wavelength division switches and space division switches required. Additional arrays of wavelength division switches or time-multiplexed wavelength division switches may be included to allow carrier frequencies to be shifted to meet the channel ordering requirements of the optical system.
