Abstract

SE PRESENTA UN APARATO PARA LA DETECCION DE PERDIDAS EN UNA RED DE FIBRAS OPTICAS RAMIFICADA QUE COMPRENDE UNA PRIMERA FIBRA OPTICA (17) Y UNA PLURALIDAD DE SEGUNDAS FIBRAS OPTICAS (A, B) CADA UNA DE LAS CUALES SE ENCUENTRA ACOPLADA A LA PRIMERA FIBRA OPTICA. LA PRIMERA FIBRA OPTICA (17) CONSTITUYE UNA LINEA PRINCIPAL Y LAS SEGUNDAS FIBRAS OPTICAS (A, B) CONSTITUYEN LINEAS SECUNDARIAS. EL APARATO CONTIENE ELEMENTOS DE LANZAMIENTO (13, 14, 16) PARA LANZAR UNA ONDA PORTADORA A LA LINEA PRINCIPAL (17), UNOS MEDIOS MODULADORES CORRESPONDIENTES (11A, 11B) EN CADA UNA DE LAS LINEAS SECUNDARIAS (A, B) PARA LA MODULACION DE LA ONDA PORTADORA EN ESA LINEA SECUNDARIA, ELEMENTO DE RETORNO (12A, 12B) PARA DEVOLVER LAS SEÑALES MODULADAS A LO LARGO DE LAS LINEAS SECUNDARIAS A LA LINEA PRINCIPAL Y ELEMENTOS DE CONTROL (20, 21A, 21B) PARA CONTROLAR LOS CAMBIOS DE MODULACION EN LA LINEA PRINCIPAL DE LAS SEÑALES DEVUELTAS. LOS ELEMENTOS DE MODULACION (11A, 11B) SON TALES QUE CADA UNO MODULA LA ONDA PORTADORADE MANERA DIFERENTE.
