Abstract[English]
Systems and methods for longitudinal performance monitoring of an optical communication line communicably connecting a transmitting device to a receiving device for transmitting a signal therebetween. The method comprises receiving the signal at the receiving device, the signal having been affected by propagative impairments accumulated along the optical communication line, generating, at the receiving device, a linear signal based on the received signal, generating, based on the linear signal, a plurality of signal templates, and determining correlation values between the received signal and each signal template of the plurality of signal templates, each correlation value being indicative of a local longitudinal performance of the optical communication line.[French]
L'invention concerne des systèmes et des procédés pour la surveillance des performances longitudinales d'une ligne de communication optique reliant de manière communicante un dispositif d'émission à un dispositif de réception pour transmettre un signal entre eux. Le procédé comprend la réception du signal au niveau du dispositif de réception, le signal ayant été affecté par des dégradations par propagation accumulées le long de la ligne de communication optique, la génération, au niveau du dispositif de réception, d'un signal linéaire sur la base du signal reçu, la génération, sur la base du signal linéaire, d'une pluralité de modèles de signaux, et la détermination de valeurs de corrélation entre le signal reçu et chaque modèle de signal de la pluralité de modèles de signaux, chaque valeur de corrélation étant indicative d'une performance longitudinale locale de la ligne de communication optique.
