The invention relates to a process for repairing a system for transmitting soliton signals via optical fibre with wavelength-division multiplexing, in which the different wavelengths (.lambda.1 to .lambda.n) of the multiplex are selected so as to ensure, over a given interval (ZR), a relative slippage between channels substantially equal to a multiple of the bit time, comprised of the following steps: - insertion of an additional length (13) of optical fibre into the transmission system and - compensation (15, 17, 19) for the effects of this additional length on the relative slippage of the different multiplex channels. It relates also to a repair device for such system for transmitting soliton signals via optical fibre with wavelength-division multiplexing. The invention prevents relative channel slippage by inserting an additional length of optical fibre into the transmission system.

L'invention concerne un procédé de réparation d'un système de transmission à fibre optique ~ multiplexage de longueur d'onde et à signaux solitons, dans lequel les différentes longueurs d'onde (.lambda.1 à .lambda.n) du multiplex sont choisies de sorte à assurer, sur un intervalle (Z R) donné, un glissement relatif entre les différents canauxsensiblement égal à un multiple du temps bit, comprenant les étapes - d'introduction d'une longueur supplémentaire (13) de fibre optique dans le système de transission et - de compensation (15, 17;, 19) des effets de cette longueur supplémentaire sur le glissement relatif des différents canaux du multiplex. Elle concerne aussi un dispositif de réparation d'un tel système de transmission à fibre optique à multiplexage de longueur d'onde et à signaux solitons. L'invention évite les glissements relatifs des canaux du fait de l'introduction dans le système de transmission d'une longueur supplémentaire de fibre.
