Abstract

L'invention se rapporte à un procédé de mise en oeuvre d'une liaison de transmission optique et à un système de transmission optique de données. Un premier ensemble de signaux optiques ayant des longueurs d'onde différentes les unes par rapport aux autres est émis à partir d'une première extrémité de la fibre optique et un second ensemble de signaux optiques ayant des longueurs d'onde différentes les unes par rapport aux autres est émis à partir de l'autre extrémité de la fibre optique. De manière à améliorer le rapport coût-efficacité du réseau, on utilise les mêmes longueurs d'onde pour le premier ensemble et le second ensemble de signaux, et en outre, on met en oeuvre un conjugateur de phase bidirectionnel (OPC) sur la fibre, qui transforme chaque longueur d'onde d'entrée une longueur d'onde donnée de sortie par repliement de la longueur d'onde en entrée par rapport à une longueur d'onde de repliement préétablie, ce qui rend possible la réception de signaux au niveau des deux extrémités de la fibre à des longueurs d'onde identiques qui sont les longueurs d'onde en sortie du conjugateur de phase.
