An optical transmitter system for supplying a plurality of different wavelength optical radiation components (.lambda.1 to .lambda.n) to a transmission element (2), which, in operation, is connected to the transmitter system for conveying the different wavelength radiation components to a respective receiver (11), is disclosed. The transmitter system comprises means for detecting a loss of a wavelength radiation component at the respective receiver (11) and means (9) for interrupting the supply of the wavelength component in response to a detection of loss of the wavelength component at the receiver. The transmitter system is characterised by timing means (10) capable of providing respective restart times (t1 to tn) which differ one to another for the wavelength radiation components, and means (9) for restarting the supply of the wavelength component, following an interruption, at the restart time provided by the timing means.

L'invention porte sur un système d'émissions de rayonnement optique produisant différentes composantes (.lambda.¿1? à .lambda.¿n?) de longueurs d'onde optiques et relié à un émetteur de manière à transmettre lesdites composantes à un récepteur (11) associé. Le système d'émission comporte un moyen de détection de la perte d'une des composantes de longueur d'onde, dans le récepteur associé (11), et un moyen (9) interrompant l'émission de ladite composante en cas de détection d'une telle perte. Le système d'émission comporte par ailleurs un minuteur (10) fixant des délais de redémarrage (t¿1? à t¿n,?), différents les uns des autres, des composantes de longueur d'onde interrompue, et en assurant le redémarrage.
