Patent

CA 2276776

This invention provides noise figure reduction and gain flatness enhancement of a fiber amplifier using multi-stage equalizing filter. According to the invention, noise figure can be lowered by splitting equalizing filter into multiple stage filtering conditions.

L'invention porte sur la réduction du facteur de bruit et sur l'amélioration du lissage du gain d'un amplificateur à fibres optiques au moyen d'un filtre d'égalisation à plusieurs étages. Selon cette invention, il est possible de réduire le facteur de bruit en réalisant le filtrage d'égalisation en plusieurs niveaux de filtrage.
