Abstract[English]
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.[French]
Les systèmes et les procédés divulgués permettent une localisation de défaut de filtre optique. La localisation de défaut de filtre optique est basée sur : i) la détermination d'une densité de bruit accumulée à des fréquences où le bruit ASE est filtré par un filtre optique défectueux dans un signal optique; ii) la comparaison de la densité de bruit accumulée avec des densités de bruit accumulées prédites, les densités de bruit accumulées prédites représentant des bruits prédits à partir d'une pluralité de filtres optiques à un récepteur; et iii) la détermination, sur la base de la comparaison de la densité de bruit accumulée et des densités de bruit accumulées prédites, d'un emplacement du filtre optique défectueux.
