Abstract

L'invention concerne un amplificateur (10) optique à bande ultralarge, car la bande optique de 1550nm divise la bande 1520nm-1610nm en trois bandes étroites, à savoir C1(1520nm-1541nm), C2(1541nm-1565nm) et L(1565nm-1610nm), et utilise trois unités séparées d'amplificateurs à fibre dopée à l'erbium (12, 14, 16) (EDFA), aménagés en parallèle et optimisés individuellement pour amplifier séparément la bande respective. On règle les problèmes de brouillage dans la propagation par trajets multiples en dotant les trois unités d'amplificateurs de la même longueur de transmission optique. Les unités d'amplificateurs de bande C1 et C2 (12, 14), qui contiennent des fibres dopées à l'erbium (44, 52) plus courtes que celles de l'unité d'amplificateur de bande L (16), sont allongées physiquement à l'aide de longueurs de fibre (70, 72) monomode, de sorte que le trajet de transmission optique de chaque unité d'amplificateur est généralement égal. Les unités d'amplificateurs (12, 16) comportent en outre des dispositifs de commande de temps de propagation (74, 76) qui commandent de manière sélective le temps de propagation des signaux traversant l'unité d'amplificateur respective (12, 16) pour assurer un réglage précis de la recombinaison de signaux.
