A multistage optical fiber amplifier (OFA) system is designed to be upgraded with the addition of pump power when signal capacity of an optical communication link is correspondingly increased. The system includes a gain flattening filter (GFF) that remains valid when the system is upgraded because of the system design. Also disclosed are ways to enhance the GFF as well as control the channel signal gain tilt as well as adjust the external gain uniformity to be the same for an assembly line of OFA systems.
L'invention concerne un système d'amplificateur à fibre optique (OFA) multi-étage, conçu de manière à évoluer par adjonction d'une puissance de pompage lorsqu'une capacité de signal d'une liaison de communications optique est augmentée de manière correspondante. Le système comprend un filtre égalisateur de gain (GFF) qui reste valide lorsque le système évolue du fait de sa conception. L'invention concerne également des moyens d'améliorer le GFF, de commander le basculement du gain de signal de canal et d'ajuster l'uniformité de gain externe de sorte qu'elle soit la même pour une ligne d'assemblage de systèmes OFA.
