Abstract
SE DESCRIBE UN SISTEMA PARA COMUNICACION DE DATOS DE PUNTO A MULTIPUNTO ENTRE UNA ESTACION CENTRAL Y UNA PLURALIDAD DE TERMINALES CONECTADAS UNA CON OTRA A LA ESTACION CENTRAL MEDIANTE UNA RED, EN PARTICULAR UNA RED OPTICA PASIVA. LA TRANSMISION DE DATOS SE REALIZA MEDIANTE MULTIPLEXADO DE DIVISION (TDM/TDMA). LA ESTACION CENTRAL TIENE UN RECEPTOR ACOPLADO DE CORRIENTE CONTINUA CON UNA AMPLIFICADOR PARA LA SEÑAL CONVERTIDA OPTOELECTRICAMENTE, CON UNA MEMORIA PARA ALMACENAMIENTO EN CADA TERMINAL DEL VALOR QUE CORRESPONDE AL NIVEL DE VALOR DE PICO, Y UN COMPARADOR QUE COMPARA LA SEÑAL CON RESPECTO AL VOLTAJE (V REF) DE REFERENCIA DERIVADO A PARTIR DEL NIVEL DEL VALOR DE TIPO DEL ESTALLIDO CORRESPONDIENTE Y DERIVADO CON RESPECTO A LA SEÑAL DIGITALIZADA. PARA REDUCIR LA COMPLEJIDAD DE HARDWARE, EL AMPLIFICADOR DISPONE DE UNA PLURALIDAD DE UNIDADES AMPLIFICADORAS PARALELAS CON FACTORES (G1, G2) DE AMPLIFICADOR CONSTANTE QUE SON SELECCIONADOS ALTERNATIVAMENTE MEDIANTE LA UNIDAD DE CONTROL DEPENDIENDO DE LOS VALORES ACUMULADOS PREVIAMENTE DEL NIVEL (V PEAK) DE VALOR DE PICO DEL ESTALLIDO CORRESPONDIENTE. OTRO COMPARADOR COMPARA LA SEÑAL AMPLIFICADA CON RESPECTO AL NIVEL DE VALOR DE PICO DEL ESTALLIDO CORRESPONDIENTE DE TAL FORMA QUE CUANDO SE DETECTA UNA DESVIACION EL VALOR ACUMULADO DEL NIVEL DE VALOR DE PICO Y EL FACTOR DE AMPLIFICACION PARA EL ESTALLIDO PRESENTE SON ADAPTADAS PASO A PASO.
