Patent

CA 2734134

A method of monitoring a WDM optical signal is provided. The method includes: receiving a WDM optical signal having a plurality of channels; detecting the optical signal after filtering the WDM optical signal with a tunable filter; and reconfiguring at least the center wavelength and bandwidth of the tunable filter optical transfer function to determine a signal performance parameter of the WDM optical signal.

Linvention concerne un procédé de contrôle dun signal optique WDM. Le procédé comprend la réception dun signal optique WDM ayant une pluralité de canaux; la détection du signal optique après le filtrage du signal optique WDM avec un filtre passe-bande; et la reconfiguration dau moins la longueur donde centrale et de la largeur de bande de la fonction de transfert optique du filtre passe-bande pour déterminer un paramètre de performance de signal du signal optique WDM.
