ABSTRACT:
In an optical fiber transmission system, signals are transmitted along a fiber optic path (11) in the form of substantially dispersion-free solitons. The transmission path includes a number of optical amplifiers (12) each of which determines, from the transmitted soliton signal purity, a gain control signal which is fed back to a previous amplifier in the path. This ensures soliton purity and optimizes the transmission power.
