Abstract

Abstract Translated from French Le dispositif de surveillance comporte des moyens d'entrée (1) pour prélever par couplage une petite portion du signal optique spectralement multiplexé à surveiller, des moyens (11) pour extraire par filtrage la partie correspondant à chaque canal dans une portion de signal prélevée et des moyens (12), coopérant avec les moyens pour extraire par filtrage, pour mesurer le niveau de puissance optique par canal dans la portion de signal prélevée. L'agencement comporte un dispositif de surveillance (0) auquel sont associés des moyens de commande (9) aptes à agir sur le signal optique spectralement multiplexé en fonction des mesures réalisées. <IMAGE> The monitoring device comprises input means (1) for sampling by coupling a small portion of the spectrally multiplexed optical signal to be monitored, means (11) for filtering out the part corresponding to each channel in a portion of the sampled signal and means (12), cooperating with the means for extracting by filtering, for measuring the level of optical power per channel in the sampled signal portion. The arrangement comprises a monitoring device (0) with which are associated control means (9) capable of acting on the optical signal spectrally multiplexed as a function of the measurements carried out. <IMAGE>
