CA 2443649

A method for upgrading bandwidth in a fiber optic system utilizing Raman amplification and having an initial band capacity provided by a plurality of pumps including the steps of identifying a fiber optic system to be upgraded (12), activating at least one new pump (16) in the fiber optic system necessary to provide upgraded band capacity to the fiber optic system while retaining the initial band capacity provided by the plurality of pumps, and adjusting power of at least one pump of the fiber optic system to minimize gain ripple or signal output ripple (18).

L'invention porte sur un procédé d'amélioration de la largeur de bande d'un système en fibres optiques utilisant l'amplification Raman et équipé d'une capacité de bande initiale fournie par plusieurs pompes. Ce procédé consiste : à identifier un système en fibres optiques à améliorer (12), à activer au moins une nouvelle pompe (16) dans le système en fibres optiques nécessaire afin de fournir une capacité de bande améliorée au système en fibres optiques tout en conservant la capacité de bande initiale fournie par l'ensemble des pompes, et à ajuster la puissance d'au moins une pompe du système en fibres optiques afin de réduire l'ondulation de gain ou l'ondulation de sortie de signal (18).
