Title (EN) FAST PROBING OF SIGNAL QUALITY IN A WDM NETWORK
(FR) SONDAGE RAPIDE DE QUALITÉ DE SIGNAL DANS UN RÉSEAU WDM
Abstract:
(EN) A method of interrogating a WDM optical communication system is provided to obtain one or more performance parameters. In accordance with the method, an optical probe wavelength is generated and possibly modulated in a prescribed manner. The probe signal is transmitted along a selected optical path through the WDM optical communication system for a duration of time that is less than a response time of network elements that impact signal quality along the selected optical path.
(FR) L'invention concerne un procédé d'interrogation d'un système de communication optique WDM permettant d'obtenir un ou plusieurs paramètres de performance. Selon le procédé, une longueur d'onde de sonde optique est générée et éventuellement modulée d'une manière prescrite. Le signal de sonde est émis sur un trajet optique choisi dans le système de communication optique WDM pour une durée de temps qui est inférieure à un temps de réponse d'éléments de réseau qui affectent la qualité du signal le long du trajet optique choisi.
