Optical telecommunication system, comprising: a transmitting station capable of transmitting a multiple-wavelength optical signal comprising at least two predetermined wavelengths, a wavelength division multiplexer for sending the said transmission signals to an optical fibre transmission line and a station for receiving the said transmission signals. The system also comprises a station for amplifying the optical signal, located between the said transmitting station and the said receiving station, comprising at least a first amplification section and at least a second amplification section and a gain stabilizing circuit. The said amplification station additionally comprises an attenuating component located between the said two sections. The said gain stabilizing circuit comprises a circuit for the recirculation of the spontaneous emission, the said circuit being common to the said first amplification section and the said second amplification section.
