Abstract

UNA FUENTE OPTICA PARA UN SISTEMA DE TELECOMUNICACIONES QUE CONSTA DE UNA FUENTE DE SEÑALES OPTICAS (1) CUYA SALIDA SE MODULA DE MODO QUE CONTENGA BANDAS LATERALES. LAS BANDAS LATERALES INTERACTUAN PARA PRODUCIR FRECUENCIAS DE BATIDO Y SE UTILIZAN UNOS ELEMENTOS MODIFICADORES (3), TAL COMO UN TROZO DE UNA FIBRA OPTICA DISPERSIVA, PARA MODIFICAR LAS CARACTERISTICAS DE LAS BANDAS LATERALES DE MODO QUE UN RECEPTOR (4) QUE COMPRENDE UN FOTODETECTOR PUEDA DETECTAR LA FRECUENCIA DE BATIDO. DE ESTE MODO SE PUEDEN GENERAR Y FOTODETECTAR SEÑALES DE ALTA FRECUENCIA, EN DONDE LA SALIDA DEL RECEPTOR (4) ES ADECUADA PARA ACCIONAR UNA ANTENA DE MICROONDAS (5) CON LO QUE SE OBTIENE UN ENLACE DE TELECOMUNICACIONES POR MICROONDAS OPTICAMENTE ALIMENTADO (6). CON LA UTILIZACION DE UN GENERADOR DE SEÑALES DE VIDEO (11), SE PUEDE SUPERPONER UNA SEÑAL DE VIDEO A LA FRECUENCIA DE BATIDO RECIBIDA Y POR TANTO LLEVADA POR EL ENLACE POR MICROONDAS.
