Abstract
La présente invention concerne un procédé de réduction des dispertions de mode et chromatique dans une fibre optique multimode. La dispersion modale et la dispersion chromatique dans une fibre optique multimode est réduite en transmettant les rayons lumineux à l'extrémité de la fibre optique, par l'intermédiaire d'un réseau de diffraction 12 de sorte que l'angle de chaque rayon par rapport à l'axe de la fibre varie en fonction de la longueur d'onde du rayon. Le rayon de longueur d'onde la plus courte est transmis à angle nul et le rayon de longueur d'onde la plus élevée selon un angle
