Abstract

SE FABRICA UN ACOPLADOR DE FIBRAS OPTICAS QUE PRESENTA PERDIDAS REDUCIDAS REALIZANDO UNA FORMA PRELIMINAR DE ACOPLADOR DOTADA DE UNA PLURALIDAD DE NUCLEOS DE VIDRIO DISPUESTOS LONGITUDINALMENTE A TRAVES DE UNA MATRIZ DE VIDRIO DE UN INDICE DE REFRACCION INFERIOR AL DE LOS NUCLEOS. DESPUES DE CALENTAR Y ESTIRAR UNA VARILLA DE VIDRIO QUE SE CORTA EN UNA PLURALIDAD DE UNIDADES LAS CUALES SE DOTAN CADA UNA DE UNA REGION CENTRAL DE DIAMETRO, REDUCIDO, CADA UNIDAD SE DOTA DE UNA PLURALIDAD DE FIBRAS OPTICAS QUE SE EXTIENDEN CADA UNA A PARTIR DE CADA UNO DE LOS NUCLEOS EN LAS CARAS DE EXTREMIDAD DE LA UNIDAD. EL METODO PREFERIDO DE FORMACION DE LAS FIBRAS OPTICAS CONSISTE EN REALIZAR LA FORMA PRELIMINAR DE ACOPLADOR CON UNA MATRIZ DE VIDRIO QUE SE DISUELVE FACILMENTE EN UN DISOLVENTE. CADA UNO DE LOS NUCLEOS DE FIBRA ESTA RODEADO POR UNA CAPA DE VIDRIO RESISTENTE A LA DISOLUCION POR UN DISOLVENTE. CUANDO SE SUMERGE EN EL DISOLVENTE UNA EXTREMIDAD DE LA UNIDAD, EL VIDRIO DE LA MATRIZ SE DISUELVE, HACIENDO QUE SOBRESALGAN A PARTIR DE LA CARA DE EXTREMIDAD RECIENTEMENTE FORMADA DE LA UNIDAD LOS NUCLEOS DE LA UNIDAD Y EL VIDRIO DE REVESTIMIENTO RESISTENTE AL DISOLVENTE QUE LOS RODEA.
