Abstract

UN SISTEMA OPTICO DE TRANSMISION Y RECEPCION PARA CONECTAR A UNA TRAYECTORIA BIDIRECCIONAL OPTICA, QUE COMPRENDE UN TRANSMISOR Y POR LO MENOS UN RECEPTOR. EL TRANSMISOR Y EL RECEPTOR ESTAN CONECTADOS A UN SISTEMA DE CONEXION POR MEDIO DE UN CIRCUITO EN HORQUILLA. EL CIRCUITO EN HORQUILLA ESTA PROVISTO CON UN PRIMER PARTIDOR DE POLARIZACION, UN ROTADOR DE POLARIZACION NO RECIPROCO, Y UN SEGUNDO PARTIDOR DE POLARIZACION, LA PRIMERA SALIDA DEL PRIMER PARTIDOR DE POLARIZACION Y LA ENTRADA DEL SEGUNDO PARTIDOR DE POLARIZACION FORMAN LA CONEXION DE ENTRADA Y LA CONEXION BIDIRECCIONAL, RESPECTIVAMENTE, DEL CIRCUITO EN HORQUILLA, Y LA ENTRADA Y SALIDA DEL ROTADOR DE POLARIZACION NO RECIPROCO ESTAN RESPECTIVAMENTE CONECTADOS A LA ENTRADA DEL PRIMER PARTIDOR DE POLARIZACION Y A LA PRIMERA SALIDA DEL SEGUNDO PARTIDOR DE POLARIZACION. LOS RECEPTORES ESTAN CONECTADOS A LAS SEGUNDAS SALIDAS DE LOS PARTIDORES DE POLARIZACION.
