Abstract

SEGUN LA INVENCION SE GENERA UNA SEÑAL OPTICA DE BASE POLARIZADA (SB) Y SE LE INYECTA A UN PRIMER EXTREMO DE UNA FIBRA OPTICA (3), SE RECUPERA, EN UN SEGUNDO EXTREMO DE LA FIBRA, UNA SEÑAL OPTICA (SE) QUE SALE DE LA FIBRA DESPUES DE SU PASO POR ESTA DE LA SEÑAL BASE; SE EFECTUA UN TRATAMIENTO DE ESTA SEÑAL SALIENTE QUE CONTIENE UNA MODULACION ELECTRO-OPTICA (24) POR LA SEÑAL ELECTROMAGNETICA A TRANSMITIR (SEL) Y UNA CONVERSION DE POLARIZACION (25) Y SE REINYECTA LA SEÑAL OPTICA ASI MODIFICADA (SM) A DICHO SEGUNDO EXTREMO DE LA FIBRA, SE RECUPERA EN EL PRIMER EXTREMO DE LA FIBRA OPTICA UNA SEÑAL OPTICA DE RETORNO (SB) BROTANDO DE LA FIBRA DESPUES DE SU PASO POR ESTA DE LA SEÑAL OPTICA MODIFICADA, Y SE LA ANALIZA (13) PARA DETERMINAR LAS CARACTERISTICAS DE DICHA SEÑAL ELECTROMAGNETICA.
