Abstract

SE FABRICA UN ACOPLADOR DE FIBRAS OPTICAS DE PERDIDAS REDUCIDAS REALIZANDO UNA FORMA PREVIA DE ACOPLADOR CON UNA PLURALIDAD DE NUCLEOS DE VIDRIO SEPARADOS DISPUESTOS LONGITUDINALMENTE EN UNA MATRIZ DE VIDRIO DE UN INDICE DE REFRACCION INFERIOR AL DE LOS NUCLEOS. LA FORMA PRELIMINAR DE ACOPLADOR SE CALIENTA Y SE ESTIRA POR UN PRIMER MEDIO DE TRACCION PARA FORMAR UNA VARILLA DE VIDRIO QUE SE ESTIRA CON UN SEGUNDO MEDIO DE TRACCION DELANTE DE UNA FUENTE INTERMITENTE DE CALOR LOCALIZADO. CUANDO SE ACTIVA LA FUENTE DE CALOR LOCALIZADO, EL SEGUNDO MEDIO DE TRACCION ESTIRA LA VARILLA HACIA ABAJO A UNA VELOCIDAD SUPERIOR A LA DEL PRIMER MEDIO DE TRACCION. PUESTO QUE LA VARILLA HA SIDO ABLANDADA POR LA FUENTE DE CALOR LOCALIZADO, SE FORMA UNA REGION DE ACOPLAMIENTO DE DIAMETRO REDUCIDO. LA VARILLA SE CORTA PARA FORMAR UNA PLURALIDAD DE UNIDADES DE ACOPLADOR. CUANDO UNA EXTREMIDAD DE UNA UNIDAD SE SUMERGE EN ACIDO, EL VIDRIO DE LA MATRIZ SE DISUELVE, HACIENDO ASI QUE LOS NUCLEOS DE LA UNIDAD Y EL VIDRIO DE REVESTIMIENTO RESISTENTE AL ATAQUE QUIMICO QUE LOS RODEA, SOBRESALGAN A PARTIR DE LA CARA DE EXTREMIDAD RECIENTEMENTE FORMADA, DE LA UNIDAD.
