Abstract
In a wavelength-division multiplexed communication system utilizing optical solitons in which optical amplifiers are inserted into an optical fiber at predetermined intervals so as to compensate for loss in the fiber, the group-velocity dispersion of the optical fiber is varied at positions where the optical amplifiers are provided as well as in regions between the optical amplifiers, so as to eliminate dispersive waves generated by the solitons, thereby eliminating disturbance due to soliton collision. This prevents time shifts due to soliton collision in different wavelength channels in a wave-length multiplex system.
