In a method and an apparatus for transmitting signals in an optical fibre, an amplitude modulator (1) is provided for amplitude modulating an optical carrier at a high frequency with the signals to be transmitted. A suppressing means (2) is provided to suppress at least part of one of the side bands of the modulated optical carrier to reduce the effect of group velocity dispersion in the optical fibre.
L'invention porte sur un procédé et un appareil de transmission de signaux dans une fibre optique comportant un modulateur de l'amplitude (1) d'un support optique a haute fréquence avec les signaux à transmettre, ainsi qu'un moyen de suppression (2) éliminant au moins une partie de la bande latérale du support optique modulé pour réduire les effets de dispersion des vitesses de groupes dans la fibre optique.
