Abstract

El sistema comprende: una fuente de luz que inyecta una señal luminosa de monitorización junto con al menos una señal luminosa de datos por medio de una señal luminosa global en una entrada de una PON; un divisor de potencia que divide dicha señal luminosa global en una pluralidad de señales subglobales; y una pluralidad de filtros cada uno de ellos conectado entre una salida de dicho divisor de potencia y una rama respectiva de dicha PON, y permitiendo cada uno de ellos el paso de dicha al menos una señal luminosa de datos y de una única longitud de onda o conjunto de longitudes de onda de dicha señal luminosa de monitorización dando como resultado una señal luminosa subglobal filtrada. El método está adaptado para usar el sistema de monitorización de capa física en PON.The system comprises: a light source that injects a light monitoring signal together with at least one data light signal by means of a global light signal at an input of a PON; a power divider that divides said global light signal into a plurality of subglobal signals; and a plurality of filters each connected between an output of said power divider and a respective branch of said PON, and each of them allowing the passage of said at least one luminous data signal and of a single wavelength or set of wavelengths of said monitoring light signal resulting in a filtered subglobal light signal. The method is adapted to use the physical layer monitoring system in PON.
