Abstract

Abstract Translated from French Système de transmission de signaux électrique, à liaison optique et dispositif de contrôle automatique du gain d'une voie de réception connectée à cette liaison, transmettant alternativement le signal utile et le signal de calibrage pouvant être dans le spectre du signal utile. Electrical signal transmission system, with optical link and automatic gain control device of a reception channel connected to this link, alternately transmitting the useful signal and the calibration signal which may be in the spectrum of the useful signal. Comporte principalement un premier commutateur, mettant en circuit alternativement, le capteur du signal utile et le générateur du signai de calibrage et un deuxième commutateur mettant alternativement la voie de réception comportant un dispositif de contrôle automatique du gain, en circuit avec la liaison optique principale et une liaison optique dérivée ne transmettant qu'une fraction de la puissance optique appliquée à la liaison principale. Mainly comprises a first switch, alternately switching on, the sensor of the useful signal and the generator of the calibration signal and a second switch alternately switching the reception channel comprising an automatic gain control device, in circuit with the main optical link and a derivative optical link transmitting only a fraction of the optical power applied to the main link. Application à l'électronique rapide. Application to fast electronics.
