Consistent with the present invention, a dispersion compensation module is provided which comprises a housing accommodating one or more spools of DCF. Each spool is provided in a respective package, which can be slidably inserted into or removed from the housing along a track provided within the housing. "Jumpers" or relatively short pieces of fiber can be used to interconnect the spools through adapters external to the packages. As a result, spools of DCF can be readily coupled to one another to provide a desired amount of dispersion compensation. Moreover, the adapters are geometrically configured so that connections can be made to the spools without excessively bending fiber interconnecting the DCF and the DCF itself, while permitting the module to conform to fiber optic packaging standards.

L'invention concerne un module de compensation de dispersion qui comprend un boîtier logeant une ou plusieurs bobines de fibre à dispersion compensée (DCF). Chaque bobine est disposée dans un emballage respectif, lequel peut être placé dans le boîtier ou extrait de celui-ci par coulissement le long d'un rail ménagé à l'intérieur du boîtier. Des "jarretières" ou pièces de fibre relativement courtes peuvent être utilisées pour interconnecter les bobines à travers des douilles situées à l'extérieur des emballages. Ainsi, les bobines de DCF peuvent être couplées facilement les unes aux autres pour fournir un niveau de compensation de dispersion désiré. De plus, les douilles sont configurées géométriquement de façon que les bobines puissent être connectées sans flexion excessive de la fibre raccordant les bobines de DCF et la DCF elle-même, et de manière à obtenir un module conforme aux normes d'emballage des fibres optiques.
