Patent CA-2307209-A1 (CA)
Inventor: MIZRAHI VICTOR
IPC: H04J14/02
Filed: 1998-10-23
Abstract: In accordance with the present invention, a WDM communication signal including a service channel is received by an add/drop multiplexer. An optical filter element included in the multiplexer separates a first optical payload channel and the service channel from the WDM signal and outputs these signals on a first output port. The remaining WDM channels exit the optical filter at a second output. By utilizing this add/drop multiplexer to select both an optical channel and a service channel, the total power loss associated with a communications network is significantly less than that obtained from networks having separate components to add/drop an optical payload channel and a service channel.
