Wavelength multiplexer/demultiplexer apparatus

摘要

An apparatus comprising an optical multiplexer/demultiplexer having a set of input ports and a set of output ports, the optical multiplexer/demultiplexer configured to demultiplex a wavelength division multiplexed optical signal to one port of the set of input ports, and to output a plurality of demultiplexed wavelength channels to one of a plurality of subsets of output ports within the set of output ports. The apparatus comprises an optical switch configured to route the wavelength division multiplexed signal to a selected one of the input ports, thereby causing the plurality of demultiplexed wavelength channels to be output by the optical multiplexer/demultiplexer to selected ones of the plurality of subsets of output ports.

1. An apparatus, comprising:
an optical multiplexer/demultiplexer having a set of input ports and a set of output ports, the optical multiplexer/demultiplexer configured to demultiplex a wavelength division multiplexed optical signal to one port of the set of input ports, and to output a plurality of demultiplexed wavelength channels to one of a plurality of subsets of output ports within the set of output ports; an optical switch configured to route the wavelength division multiplexed signal to a selected one of the input ports, thereby causing the plurality of demultiplexed wavelength channels to be output by the optical multiplexer/demultiplexer to selected ones of the plurality of subsets of output ports; and a control module configured to control the routing of the wavelength division multiplexed input signal to the selected one of the input ports of the optical multiplexer/demultiplexer, wherein the control module is configured to send one or more control signals to the optical switch to thereby cause the optical switch to successively send the wavelength division multiplexed optical signal from the input switch port to each one of the plurality of output switch ports.
