Abstract:
An optical system may include: a demultiplexer to receive an optical signal and to demultiplex the optical signal into a plurality of optical channels; a detector circuit to: receive the plurality of optical channels, and identify a predetermined channel identification trace tone frequency for an optical channel of the plurality of optical channels; and a receiver to: receive the optical channel with the identified predetermined channel identification trace tone frequency from the detector circuit, and process the optical channel.
