Abstract[English]
The disclosed systems and methods are for monitoring optical performance in a spatial division multiplexing (SDM) system, comprising: i) extracting, by an optical coupler, at least a portion of a plurality optical signals propagating in different communication lanes of the SDM-based optical communication system, wherein each optical signal of the plurality of optical signals is modulated with a distinguishable pilot tone (PT) signal; ii) combining, by the optical coupler, the extracted portion of the plurality of optical signals, and generate a combined optical signal; iii) extracting, by a pilot tone detector (PTD), PT signals from the combined optical signal; iv) determining, by the PTD, optical signal specific information included in the PT signals; and v) computing, by the PTD, optical power of each optical signal based on the optical signal specific information.[French]
Les systèmes et les procédés divulgués sont destinés à surveiller les performances optiques dans un système de multiplexage par répartition spatiale (SDM), comprenant : i) l'extraction, par un coupleur optique, d'au moins une partie d'une pluralité de signaux optiques se propageant dans différentes voies de communication du système de communication optique à base de SDM, chaque signal optique de la pluralité de signaux optiques étant modulé avec un signal de tonalité pilote (PT) discernable ; ii) la combinaison, par le coupleur optique, de la partie extraite de la pluralité de signaux optiques et la génération d'un signal optique combiné ; iii) l'extraction, par un détecteur de tonalité pilote (PTD), des signaux PT à partir du signal optique combiné ; iv) la détermination, par le PTD, des informations spécifiques à un signal optique incluses dans les signaux PT ; et v) le calcul, par le PTD, de la puissance optique de chaque signal optique sur la base des informations spécifiques au signal optique.
