Abstract
In an optical transmission method solitons are transmitted through a succession of fibers in which their intensity progressively decreases. To limit distortion of the solitons, this decrease in their intensity is accompanied by a decrease in the chromatic dispersion of the fibers. In accordance with the invention, the succession of fibers includes at least a first fiber featuring continuously longitudinally decreasing chromatic dispersion. Subsequent fibers feature respective longitudinally constant chromatic dispersions forming a longitudinally decreasing sequence. Applications include telecommunications.
