Abstract
Systems and methods include obtaining power measurements from one or more first components in an optical node and store the power measurements at corresponding vertices in a graph that describes the optical node; obtaining calibration data from a plurality of second components in the optical node and utilize the calibration data to determine an optical gain or an optical loss through an associated arc in the graph; and determining an optical power at any point in the optical node via traversing the graph, for any of configuration and operation of the optical node. The graph includes the vertices that are points in the optical node where there is a need for optical power, the arcs that are connections through the optical node where the optical power has the optical gain or the optical loss, and optical channels and their associated optical spectrum.
