Title:
SYSTEMS AND METHODS FOR OPTICAL FILTER FAULT LOCALIZATION
Document Type and Number:
WIPO Patent Application WO/2023/138516
Kind Code:
A1
Abstract:
The disclosed systems and methods for optical filter fault localization. The optical filter fault localization is based on: i) determining an accumulated noise density at frequencies where ASE noise is filtered out by a faulty optical filter in an optical signal; ii) comparing the accumulated noise density with predicted accumulated noise densities, the predicted accumulated noise densities representing noises predicted from a plurality of optical filters to a receiver; and iii) determining, based on the comparison of the accumulated noise density and the predicted accumulated noise densities, a location of the faulty optical filter.
