Abstract

Red óptica de conexión de abonados con una central (1) de conmutación final, cuya salida está conectada por medio de una línea (5) de transmisión con la entrada de un armario (6) de distribución de cables, al mismo tiempo, que en el caso de la detección con una longitud (c) de onda de control de un fallo de la línea (5) de transmisión se pueden conectar la salida de la central (1) de conmutación final y la entrada del armario (6) de distribución de cables con una línea (12) de reserva, caracterizada porque las salidas de la líneas (5) de transmisión y de la línea (12) de reserva están conectadas con el armario (6) de distribución de cables a través de la conexión en serie de un divisor (13) de potencia pasivo y de una unidad (7) de reflexión sintonizada con la longitud (c) de onda de control.
