ABSTRACT:
A system for transmission of a digital signal on a transmission line with an optical on-line amplification. The transmission line is formed by a plurality of optical fiber sections and a plurality of optical amplifiers. Each of the optical amplifier is interposed between two adjacent optical fiber sections. The system includes at least one device for on-line compensation of the distortions induced in the digital signal, notably by the noise and the propagation on the transmission line. The on-line compensation device includes at least one bandpass optical filter having a passband whose value is substantially lower than that of the passband of the digital signal before transmission, and at least one saturable absorbent element that is a non-linear passive optical element having an absorption that depends decreasely on the optical power.
