Abstract

UN SISTEMA DE TELECOMUNICACION OPTICA, QUE COMPRENDE: A) POR LO MENOS DOS FUENTES DE SENALES OPTICAS MODULADAS A DIFERENTES VELOCIDADES DE ONDA, INCLUIDAS EN UNA BANDA PREDETERMINADA DE LONGITUD DE ONDA DE LA TRANSMISION; B) MEDIOS PARA MULTIPLEXAR DICHAS SENALES PARA INGRESARLAS A UNA SOLA FIBRA OPTICA; C) UNA LINEA CON FIBRA OPTICA CONECTADA A UN EXTREMO DE DICHO MEDIO MULTIPLEXOR; D) MEDIOS PARA RECIBIR DICHAS SENALES COMPRENDIENDO MEDIOS DE MULTIPLEXION OPTICA PARA LAS SENALES MISMAS, DEPENDIENDO DE LA LONGITUD DE ONDA RESPECTIVA. DICHO SISTEMA ESTA CARACTERIZADO EN QUE LA FIBRA OPTICA TIENE UNA DISPERSION CROMATICA QUE AUMENTA CON EL AUMENTO DE LONGITUD DE ONDA, TENIENDO UN VALOR CERO A UNA LONGITUD DE ONDA QUE LA LONGITUD DE ONDA MINIMA DE DICHA BANDA, EN UNA CANTIDAD TAL QUE NINGUN VALOR LOCAL CERO DE DISPERSION CROMATICA ESTE INCLUIDO EN DICHA BANDA. SE USA EN EL CAMPO DE LA TRANSMISION DE SENALES DE FRECUENCIA PREDETERMINADA QUE LLEVAN INFORMACION A SER COMUNICADA A DISTANCIA
