CA 2413998

A monitor device and method for monitoring operating conditions of a wavelength division multiplexed optical signal. The monitor device includes an optical engine for receiving the multiplexed optical signal and generating a plurality of demultiplexed optical signals. An array of optical detectors is disposed to receive the demultiplexed optical signals from the optical engine. The demultiplexed optical signals form spots on the array of optical detectors. At least one spot is wider than a center-to-center dimension spanning two optical detector elements in the array of optical detectors.

L'invention concerne un dispositif et un procédé de surveillance servant à surveiller les conditions d'exploitation d'un signal optique multiplexé en longueur d'onde. Le dispositif de surveillance comprend un moteur optique destiné à recevoir le signal optique multiplexé et à générer plusieurs signaux optiques démultiplexés. Un réseau de détecteurs optiques est destiné à recevoir les signaux optiques démultiplexés du moteur optique. Les signaux optiques démultiplexés forment des points sur le réseau de détecteurs optiques. Un point au moins est plus large que la dimension de centre à centre englobant deux éléments détecteurs optiques du réseau de détecteurs optiques.
