Abstract:
An optical router, comprising:at least one input fiber for receiving one or more optical data packets; a plurality of input demultiplexers for demultiplexing said data packets; an optical-to-electric converter associated with the output of each input demultiplexer for converting header information from each of said data packets into electric form; a control unit for processing said header information and generating control signals to control data packet routing through said optical router; a space switch block for routing each data packet based on a current output status; a wavelength conversion module for assigning a different internal wavelength to data packets selected for conversion based on said current output status; a secondary space switch block for routing said wavelength converted data packets based on said current output status; a buffer, for applying a preset level of delay to data packets selected for delay based on said current output status by said space switch block and said secondary space switch block; a secondary demultiplexer associated with the output of said buffer for demultiplexing data packets selected for delay; a delay space switch block for routing said delayed data packets based on said current output status; and at least one output fiber for outputting said data packets from said optical router.
