Method for lightpath monitoring in an optical routing network
A method and system for enabling lightpath monitoring in an optical network is disclosed. A single polarization modulator/scrambler introduces a pilot tone signal as an overlay on a plurality of optical signals on a source node and a performance monitoring unit detects the pilot tone signal to enable light path monitoring and identification through the optical network.
