Abstract
LA INVENCION SE REFIERE A UN AMPLIFICADOR OPTICO EN PARTICULAR PARA LINEAS DE TELECOMUNICACION DE FIBRA OPTICA QUE COMPRENDE UNA FIBRA ACTIVA (7) QUE CONTIENE UN ELEMENTO FLUORESCENTE EN EL NUCLEO OPTICO RESPECTIVO QUE PRODUCE UNA EMISION EN LA LONGITUD DE ONDA DE LA SEÑAL DE TRANSMISION A SER AMPLIFICADA, A DICHA FIBRA OPTICA SE SUMINISTRA UNA SEÑAL DE BOMBEO LUMINOSO. LA FIBRA OPTICA ACTIVA (7) ES UNA FIBRA QUE EN UNA CONFIGURACION SUBSTANCIALMENTE RECTILINEA PERMITE LA PROPAGACION DE LA LUZ EN MODO SIMPLE EN LA LONGITUD DE ONDA DE LA TRANSMISION Y LA PROPAGACION DE LA LUZ EN MODO MULTIPLE EN LA LONGITUD DE ONDA DEL BOMBEADO Y ESTA DISPUESTA, AL MENOS SOBRE EL 70 % DE LA LONGITUD DE LA MISMA, EN UNA CONFIGURACION CURVA (11) CON UNA RADIO DE CURVATURA QUE SE CORRESPONDE CON EL DE LA PROPAGACION HACIA LA FIBRA MISMA DEL MODO FUNDAMENTAL, SOLAMENTE EN LA LONGITUD DE ONDA DEL BOMBEADO, REDUCIENDO, DE ESTA MANERA, EL DIAMETRO DEL MODO EN LA LONGITUD DE ONDA DE LA TRANSMISION; SIN TRANSMITIR MODOS SUPERIORES PARA LA SEÑAL DE BOMBEO.
