Abstract (en)
[origin: WO9940697A1] A system (20) for communicating on an optical wavelength division multiplexed ring network (22) using terminal nodes (26) and a head-end node (24) is provided. Each terminal node has a communication subsystem (30) to receive and to transmit signals at a particular wavelength, a tributary subsystem (34) to enable a plurality of devices to communicate over the network, and a multiplexing subsystem (32) to channel signals between the devices and the ring network. The head-end node includes a demultiplexer (72) to isolate signals received from the terminals, an integral cross-connect module (58) to determine output wavelengths at which to transmit received signals, and a multiplexer (70) to combine the received signals for transmission on the network.
