Abstract

METODO PARA ECUALIZAR EL RETARDO DEPENDIENTE DE LA LONGITUD DE ONDA EN FIBRAS OPTICAS MONOMODO. CONSISTE EN INTRODUCIR UN HAZ DE LUZ EN UNA FIBRA MONOMODO (1) CUYO HAZ EMERGENTE SE LE HACE INCIDIR SOBRE UN ELEMENTO DE DISPERSION (2), PUDIENDO UTILIZARSE UNA LENTE (3) PARA EL ENFOQUE. LA LUZ REFLEJADA SE DIRIGE ENTONCES AL EXTREMO DE UNA LONGITUD DE FIBRA DE INDICE DE SALTO MULTIMODO (4). ADMITE ALTERNATIVAS DE UTILIZACION DE DIFERENTES FIBRAS MULTIMODO. ESPECIALMENTE APLICABLE A SISTEMAS DE TELECOMUNICACION POR FIBRA OPTICA.
