An optical transmission system (1) comprises an optical fiber transmission channel (30) between a transmitting station (10) and a receiving station (20). The receiving station (20) includes an optical amplifier (21), a dispersion compensator (22), an optical amplifier (23), and a receiver (24). The dispersion compensator (22) includes two types of dispersion compensating optical fibers (221, 222) connected together. The dispersion slope compensation of the optical fibers (221, 222) is greater than 60%; one of the two fibers has dispersion slope compensation greater than 80% and the other 60% - 100%.

La présente invention concerne un système de transmission optique (1) qui comprend un canal de transmission par fibre optique (30) entre une station émettrice (10) et une station réceptrice (20). La station réceptrice (20) est équipée d'un amplificateur optique (21), d'un correcteur de dispersion (22), d'un amplificateur optique (23) et d'un récepteur (24). Le correcteur de dispersion (22) comporte deux types de fibres optiques (221, 222) à correction de dispersion montées ensemble. La correction de pente de dispersion des fibres optiques (221, 222) est supérieure à 60%. L'une des deux fibres présente une correction de pente de dispersion supérieure à 80%, la correction étant de 60% - 100% pour l'autre.
