Optical node system for a ring architecture and method thereof

Abstract From the Canadian patent

An optical node system for an optical ring network reduces certain costs associated with current ring architectures by using at least a portion of the light from an incoming optical signal to transmit an outgoing optical signal. In accordance with certain embodiments the node includes an optical multiplexer which receives optical signals having a plurality of wavelengths. The optical multiplexer can be configured to output optical signals having certain wavelengths and to route at least one optical signal from the ring of at least one particular wavelength (or wavelength band) to a corresponding optical transceiver. The optical transceiver receives the incoming optical signal of the …
