Abstract
A high-transmission-speed optical connection comprising a pulse-generation laser source, optical-fibre transmission means and a receiver, in which said optical-fibre means forms an optical fibre path, such that a pulsed signal of the soliton type is subjected to a broadening in time greater than 50% by effect of the chromatic dispersion, in which said laser source comprises an active and harmonic mode-locking optical-fibre laser wherein the fibre length, filter pass-band and power in the cavity are selected for emitting pulses of a Gaussian temporal profile having such a duration and bandwidth that, at the receiver, the duration of the pulses themselves is not more than 15% higher than the duration at the emission.
