Abstract

Método y sistema para la monitorización de capa física en redes ópticas pasivas El sistema comprende: una fuente (2) de luz que inyecta una señal luminosa de monitorización de longitud de onda variable en una entrada de una PON; reflectores (8) ópticos previstos en diferentes puntos de dicha PON para recibir la señal luminosa de monitorización y reflejar de vuelta, cada uno, aquella parte de dicha señal luminosa de monitorización que tiene una longitud de onda específica e individualizada; medios (17) de detección de luz dispuestos para recibir dichas señales luminosas reflejadas; y medios de análisis conectados a dichos medios (17) de detección de luz y con acceso al conocimiento previo acerca de qué longitud de onda específica refleja cada reflector (8), para determinar la ubicación de cada uno de los reflectores (8) ópticos en función del orden de llegada, en dichos medios (17) de detección de luz, de su respectiva señal reflejada. El método está adaptado para usar el sistema para la monitorización de capa física en PON.
