Abstract:
A method of stabilizing managed optical solitons propagating in a dispersion-managed optical fiber transmission line (7), in which method the following are performed once or more than once along the transmission line (7) for each managed optical soliton:a first step consisting in establishing coupling that is substantially linear between the energy and the spectrum width of the optical soliton by amplifying the managed optical soliton and feeding it into a fiber (40) having non-linear effects; and a second step consisting in setting the spectrum width by filtering, and, by means of the substantially linear coupling, in setting the energy of the soliton resulting from the first step, the center frequency of the filtering being substantially equal to the center frequency of the optical soliton, said method being characterized in that, in the first step, all of the solitons are spectrally widened in said fiber (40) having non-linear effects.
