Abstract
A transmission system includes: an optical transmission module capable of modulating a first digital radio signal in order to obtain a first optical signal; an optical reception module capable of receiving a second optical signal and demodulating same in order to obtain a demodulated radio signal; and a digitizing module capable of digitizing the demodulated radio signal in order to obtain a second digital radio signal. The transmission module includes: a module for adding a first management signal to the first digital radio signal, the rate of the first management signal being less than that of the first digital radio signal. The optical digitizing module includes an extraction module capable of extracting a second management signal from the demodulated radio signal, the rate of the second management signal being less than that of the second digital radio signal.
