Abstract

Un sistema de senales opticas en una trayectoria de retorno incluye un transmisor (20) que tiene un generador de reloj de muestras (212) para generar un reloj de muestras (213) y un receptor de senales RF (202-1) para recibir y convertir una senal de datos de RF analogicas en un primer flujo de datos de muestras de datos de RF digitalizadas (Data-1) a una velocidad determinada por el reloj de muestras. Circuitos de canales complementarios (202-2) proporcionan un segundo flujo de datos (Data-2) Un multiplexor (204) recibe y combina el primer flujo de datos (Data-1) y un segundo flujo de datos (Data-2), y un transmisor optico (206) convierte el flujo de datos combinado en una senal de datos optica, serializada para la transmision optica sobre una fibra optica (210). El segundo flujo de datos puede contener datos de mantenimiento que manifiestan un estado operativo del transmisor.
