Techniques for parameter reporting of elements in an optical transmission system using high loss loopback (HLLB) data and a line monitoring system implementing the same

An optical communication system comprising:

• an optical transmission path;
• a plurality of repeaters coupled to the optical transmission path, each of the plurality of repeaters comprising a high loss loopback (HLLB) path;
• first line monitoring equipment (LME) coupled to a first end of the transmission path, the first LME being configured to transmit first LME test signals on the optical transmission path and receive a first LME loopback data from the optical transmission path in response to the first LME test signals, the first LME loopback data comprising a peak associated with a location of each of the HLLB paths on the transmission path;
• a controller coupled to the first LME, the controller to:
• generate a plurality of operational parameters based on the first LME loopback data, each of the operational parameters corresponding to a repeater of the plurality of repeaters, wherein each of the plurality of operational parameters are stored in a lookup table in a memory, the lookup table associating each of the plurality of repeaters with corresponding operational parameters;
• select one or more repeaters of the plurality of repeaters;
• and
• send a reporting message to a remote computer, the reporting message including a representation of one or more operational parameters of the plurality of operational parameters associated with each of the selected repeaters.
