Abstract

Abstract Translated from French La présente invention concerne un dispositif de stabilisation de la puissance de sortie d'un module émetteur pour un système de transmission sur fibre optique. Ce dispositif comporte un premier (20) de stabilisation de la valeur moyenne de la puissance optique émise par une diode laser (11) connecté entre des moyens de conversion (12) de la puissance optique en puissance électrique et la diode laser, et un second circuit (30) de stabilisation de l'amplitude de modulation de la puissance optique émise par la diode laser connecté entre les moyens de conversion (12) et la diode laser (11). La dispositif de stabilisation selon l'invention s'applique aux télécommunications par fibres optiques. The present invention relates to a device for stabilizing the output power of a transmitter module for a fiber optic transmission system. This device comprises a first (20) for stabilizing the average value of the optical power emitted by a laser diode (11) connected between means (12) for converting optical power into electrical power and the laser diode, and a second circuit (30) for stabilizing the amplitude of modulation of the optical power emitted by the laser diode connected between the conversion means (12) and the laser diode (11). The stabilization device according to the invention applies to telecommunications by optical fibers.
