Abstract: A long-distance optical transmission system comprising pulse emitter and receiver means (1, 2) and an optical line (3) which extends between said emitter and receiver means (1, 2) and which comprises alternating segments (3a, 3b) of dispersive fibers having chromatic dispersion of opposite signs, and also having a plurality of amplifiers (4), the system being characterized in that the optical line (3) comprises a plurality of pairs of dispersive fiber segments (3a, 3b) having chromatic dispersion of opposite signs between successive amplifiers (4), and in that the cumulative dispersion C over the majority of the segments of the optical line satisfies the relationship (R)nullCnullnullnull2
