Disclosed is a dispersion compensated multimode waveguide fiber link. The dispersion of essentially any wavelength can be compensated by adding a compensating waveguide fiber to the link, the compensating waveguide having a profile shape and a .lambda.p wavelength which counters dispersion caused by the original waveguide fiber of the link. Analytical expressions relating the compensator waveguide profile and .lambda.p to the original link and compensated profile and .lambda.p are provided for the embodiment which includes .alpha. profiles.

L'invention porte sur une liaison à fibres optiques multimode de guide d'onde à compensation de dispersion. La dispersion de n'importe quelle longueur d'onde peut être compensée en ajoutant une fibre de guide d'onde de compensation à la liaison, le guide d'onde de compensation ayant une forme profilée et une longueur d'onde .lambda.¿p? qui évalue la dispersion provoquée par la fibre d'origine du guide d'onde de la liaison. Selon une réalisation comprenant des profils .alpha., on obtient des expressions analytiques relatives au profil du guide d'onde du compensateur et à .lambda.¿p? par rapport à la liaison d'origine, et relatives au profil compensé et à .lambda.¿p?.
