Control information is embedded in the signal passing through an optical amplifier by varying the power level of that amplifier's pumped laser source. Connection discovery for a given optical port can then be performed by detecting variations in the optical signal present on that given port and then attempting to match these with the variations assigned to each of the optical amplifiers. If a match is found, then the optical amplifier connected to the given port can be identified. As a result, the need to physically handle the fiber in order to effect connection discovery is eliminated, rendering the process faster, safer and more reliable. Also, the present invention advantageously allows a connection discovery function to be invoked from a remote location.
