TECHNIQUES FOR HIGH-RESOLUTION LINE MONITORING WITH A STANDARIZED OUTPUT AND AN OPTICAL COMMUNICATION SYSTEM USING THE SAME

摘要

Techniques for providing high-resolution, standard-format output for line monitoring equipment (LME) of a wavelength division multiplexed (WDM) communication system is disclosed. LME may transmit a plurality of LME test signals via an optical path of the WDM system and perform gain measurements on reflections associated with the same at predetermined intervals. Gain measurements for each of the plurality of LME test signals may be normalized and filtered to derive LME peak data. The WDM communication system may perform full scans with data points totaling millions/billions (e.g., depending on system length, fiber type, and number of transmitted LME test signals or test pulses) and normalize the same into a relatively small number of resulting data points within the LME peak data. The WDM system may then output an LME results file in a standard format which is compatible with commercial viewers and optical time domain reflectometer (OTDR) equipment.
