Abstract
The invention concerns a wavelength-division multiplex soliton signal fiber optic transmission system; to reduce the effects of collision jitter on the soliton channels, it proposes quasi-distributed amplification combining lumped amplification and distributed amplification. In this way it is possible to combine pumping of a lightly doped line fiber an dumped amplification by an EDFA in the repeaters. Reduncant and common pumping means are advantageously used for the lumped amplification and the distributed amplification and the gain of the lumped amplification is advantageously controlled automatically.
