OPTICAL COMMUNICATION SYSTEM

摘要

An optical communication system having nodes that include add/drop units having a network input port for receiving optical energy having a plurality of different wavelengths from other nodes in the network; a network output port for coupling to destination nodes in the network; an add port for receiving optical energy having the plurality of different wavelengths from a local source for transmission to other nodes in the network; and a drop node for receiving optical energy from other nodes in the network for local processing. A wavelength demultiplexer is included to separate the plurality of wavelengths received by the network input port and a wavelength multiplexer is included to combine the plurality of wavelengths received from the electronically controlled beam steerer for delivery to the network output port for transmission to other nodes in the network.
