Abstract: An interface mapping method includes obtaining, at a network controller, device information of network devices configured to be in communication with each other through an optical network. The network devices include a plurality of colored interfaces that support a range of wavelengths for communication in the optical network. Interface information of the colored interfaces of the network devices is obtained, and optical power information associated with each of the colored interfaces is obtained. Optical power margins for a transmitter interface of the colored interfaces. The transmitter interface is controlled to transmit a power sequence based on the optical power margins, and power readings are obtained from a receiver interface of the colored interfaces. A topology between the colored interfaces is discovered based on the power sequence and the power readings.
