Abstract

El método comprende: inyectar una señal luminosa de monitorización a una entrada de una red óptica pasiva, o PON, para que circule a través de la misma; reflejar, reflectores ópticos previstos en diferentes puntos de dicha PON, al menos parte de dicha señal luminosa de monitorización, en forma de respectivas señales luminosas reflejadas; y analizar dichas señales luminosas reflejadas recibidas para realizar una monitorización de capa física de la PON; estando el método caracterizado porque comprende además, para realizar dicha supervisión simultáneamente al funcionamiento normal de la PON basándose en la inyección de una señal luminosa de trabajo: a) desviar dicha señal luminosa de monitorización hacia una unidad de acondicionamiento intermedia; y b) dividir al menos, en dicha unidad de acondicionamiento intermedia, dicha señal luminosa de monitorización desviada, y enviar a cada rama de dicha PON al menos parte de una de las señales resultantes de dicha división. El sistema está dispuesto para implementar el método de la presente.The method comprises: injecting a light monitoring signal to an input of a passive optical network, or PON, to circulate through it; reflect, optical reflectors provided at different points of said PON, at least part of said light monitoring signal, in the form of respective reflected light signals; and analyzing said reflected light signals received to perform a physical layer monitoring of the PON; the method being characterized in that it further comprises, to perform said supervision simultaneously to the normal operation of the PON based on the injection of a working light signal: a) diverting said light monitoring signal to an intermediate conditioning unit; and b) dividing at least in said intermediate conditioning unit, said deviated monitoring light signal, and sending to each branch of said PON at least part of one of the signals resulting from said division. The system is arranged to implement the method of this.
