ABSTRACT:
One method embodiment for monitoring an optical pathway includes emitting an optical signal from an optical emitter, encoding the optical signal with a monitoring optical code division multiple access (OCDMA) code, directing the optical signal with the monitoring OCDMA code into the optical pathway, receiving reflected light associated with the monitoring OCDMA code from the optical pathway, and determining a status of the optical pathway based on the reflected light.
