Patent

CA 2713638

There is provided a method and apparatus for tuning an optical discriminator to the carrier frequency of an optical signal to allow superior reception of said signal. The carrier frequency of the signal is dithered during a test phase in order to pro-vide information that allows a subsequent tuning phase to optimise the reception of the optical signal, as measured by a signal quality metric. The tuning phase may comprise adjustment of one or both of the carrier frequency and the optical discriminator.

L'invention concerne un procédé et un appareil pour accorder un discriminateur optique sur la fréquence porteuse d'un signal optique pour permettre une meilleure réception dudit signal. On fait vibrer la fréquence porteuse du signal pendant une phase d'essai de façon à fournir des informations qui permettent à une phase d'accord subséquente d'optimiser la réception du signal optique, tel que mesuré par une métrique de qualité de signal. La phase d'accord peut consister à ajuster la fréquence porteuse et/ou le discriminateur optique.
