In an optical communication network, optical communication nodes exchange information detailing power level variations to support management and administration of optical communications. This exchange of information permits nodes to determine aggregate power level variations over light paths to support operations such as selection from available light paths and configuration of optical communication characteristics.

Power level management in optical networks

A method for optical supervisory signaling includes determining a wavelength channel status (WCS) value, a wavelength channel failure (WCF) value, and a wavelength channel lit (WCL) value for each one of multiple data channels services by an optical communication node. The method further includes communicating the values to a second optical communication node.

Sharing of power level information to support optical communications

A method for automatically setting a gain for an amplifier in an optical network includes transmitting, from a source proximate an upstream amplifier coupled to an optical span, a stable signal over the optical span. The method also includes using the stable signal at a downstream amplifier coupled to the optical span to automatically set a gain of the downstream amplifier.
