Le dispositif de transmission (1) émet un faisceau d'entrée vers le dispositif de division de faisceau (3), et le dispositif de division de faisceau (3) divise le faisceau d'entrée, un des faisceaux d'entrée étant entré dans le premier dispositif de réflexion (4) et réfléchi vers le dispositif de surveillance (2) au moyen du premier dispositif de réflexion (4); le dispositif de surveillance (2) reçoit le faisceau réfléchi, détecte un paramètre de puissance du faisceau réfléchi, et transmet le paramètre de puissance du faisceau réfléchi au dispositif de commande principal (5); et le dispositif de commande principal (5) commande la puissance d'émission du dispositif d'émission (1) en fonction du paramètre de puissance du faisceau réfléchi. Selon la présente invention, une division et une rotation de trajet de faisceau optique sont mises en œuvre dans un module optique SR4, et un faisceau de transmission est commandé au moyen de la détection d'un faisceau réfléchi de façon à surveiller directement la puissance de transmission, ce qui permet d'éviter le vieillissement d'un dispositif ou d'un changement de température ayant une influence sur la surveillance.
