Abstract
UNA RED OPTICA PASIVA QUE INCLUYE UNA CENTRAL TERMINAL DE CABEZA (1) Y UNA PLURALIDAD DE TERMINALES (2). LAS TERMINALES (2) SON RESPONSABLES DEL CONTROL DE SEÑALES DESDE LA CENTRAL TERMINAL DE CABEZA (1). LA CENTRAL TERMINAL DE CABEZA (1) ESTA MONTADA PARA RECIBIR MARCOS TENIENDO UNA VELOCIDAD DE BIT PREDETERMINADA Y COMPRENDEN SEÑALES TRANSMITIDAS POR LAS TERMINALES (2). LOS IMPULSOS A DISTANCIA SON TRANSMITIDOS DESDE CADA UNA DE LAS TERMINALES (2) A LA CENTRAL TERMINAL DE CABEZA (1) DONDE LOS IMPULSOS A DISTANCIA RECIBIDOS SON MUESTREADOS A UNA VELOCIDAD DE MUESTREO ALTA MAYOR QUE LA VELOCIDAD DE BIT PREDETERMINADA. LAS MUESTRAS DE DATOS SE APLICAN A UN PROCESADOR (7) QUE DETERMINA LA FASE Y AMPLITUD DE LOS IMPULSOS A DISTANCIA Y GENERA SEÑALES DE CONTROL PARA LAS TERMINALES (2) PARA MODIFICAR LA FASE O TEMPORIZACION Y AMPLITUD DE LAS TRANSMISIONES DESDE LAS TERMINALES (2). SE PUEDE APLICAR UN IMPULSO MARCADOR GENERADO LOCALMENTE AL MARCO DE DATOS ENTRANTES ANTES DE QUE SEA MUESTREADO ENLA CENTRAL TERMINAL DE CABEZA (1), PROPORCIONANDO EL IMPULSO MARCADOR UNA REFERENCIA DE FASE Y AMPLITUD PARA UTILIZAR POR EL PROCESADOR DE CONTROL.
