Abstract

SISTEMA OPTICO DE TRANSMISION CON VARIOS TRANSDUCTORES SITUADOS A INVERVALOS A LO LARGO DE UNA LINEA CONTINUA DE FIBRA OPTICA DE TRANSMISION DE DATOS. LAS SEÑALES DE DATOS PROCEDEN DE LOS RESPECTIVOS TRANSMISORES ASOCIADOS A LOS TRANSDUCTORES Y SE APLICAN A ESTOS PARA PRODUCIR TENSION O DEFORMACION MECANICA DE LA LINEA DE FIBRA OPTICA DE TRANSMISION DE DATOS PARA DAR LA CORRESPONDIENTE MODULACION DEL ESTADO DE POLARIZACION DE LA LUZ QUE SE PROPAGA A LO LARGO DE LA FIBRA OPTICA. UN RECEPTOR CONECTADO AL EXTREMO FINAL DE LA LINEA DE TRANSMISION TIENE UN ELEMENTO PARA DETERMINAR EL ESTADO EXACTO DE POLARIZACION DE LA LUZ RECIBIDA, EXTRAER LA INFORMACION DE LA MODULACION Y, EN CONSECUENCIA, LOS DATOS TRANSMITIDOS.
