Abstract:
1. A method for stabilizing a color coding for optical transmission of data, comprising: providing a color coding method based on a plurality of elementary colors for transmission of data between a transmitter and receiver, transmitting a respective elementary color by at least one transmitter-end optical radiation source and receiving the respective elementary color at the receiver end by at least one respective optical radiation receiver, forming by the transmitter at least one calibration message defining, for at least one time sequence, an adjustment of a value of an analog transmission parameter of optical performance of at least one optical radiation source allocated to an elementary color, sending the at least one calibration message by the transmitter, including implementing the adjustment of the value of the analog transmission parameter of optical performance of the at least one optical radiation source, receiving the at least one calibration message at the receiver, and determining and sending to the transmitter a signal representing a respective value of an analog reception parameter of an optical performance received at the respective optical radiation receiver, comparing by the transmitter the respective value representing the analog reception parameter of the optical performance received at the respective optical radiation receiver with the respective adjusted value of the analog transmission parameter of the optical performance sent at the respective optical radiation source, based on the comparison, determining compensation information and adjusting at least one transmission parameter based on the determined compensation information.
