Abstract

Se trata de una unidad amplificadora optica (100:100) para amplificar senales opticas en un sistema de transmision optica que presenta una banda delongitud de onda de amplificacion con un límite de longitud de onda inferior mayor que 1570 nm y que incluye una entrada (101) para la entrada de senalesopticas, una salida (102) para la salida de senales opticas. y un amplificador optico (104) intercalado entre la entrada (101) y la salida (102) paraamplificar las senales opticas. El amplificador optico (104) incluye una fibra de amplificacion (108) co-impurificada con erbio e iterbio, al menos una fuentede bombeo (109,110) para generar radiacion de bombeo y al menos un acoplador optico (111,112) que acopla opticamente las fuentes de bombeo (109,110) a lafibra de amplificacion (108). La unidad de amplificacion optica presenta una ganancia de energía de al menos 31 dB cuando las senales opticas presenten unapotencia de entrada de al menos -10,5 dBm y longitudes de onda dentro de la banda delongitud de onda de amplificacion.
