ABSTRACT:
An optical transmitter system supplies a plurality of different wavelength optical radiation components to a transmission element which, in operation, is connected to the transmitter system for conveying the different wavelength radiation components to a respective receiver. The transmitter system detects a loss of a wavelength radiation component at the respective receiver. The supply of the wavelength component is interrupted in response to a detection of loss of the wavelength component at the receiver. A timing circuit provides respective restart times which differ one to another for the wavelength radiation components. The supply of the wavelength component is restarted, following an interruption, at the restart time provided by the timing circuit.
