Abstract
SE FORMA UN ACOPLADOR DE FIBRAS OPTICAS PROVEYENDO UN TUBO DE VIDRIO 10 QUE TIENE UNA ABERTURA LONGITUDINAL 11 QUE SE EXTIENDE A TRAVES DEL MISMO. SE EXTRAE DE UNA PRIMERA FIBRA OPTICA 17 UN RECUBRIMIENTO PROTECTOR 21 ENTRE LOS EXTREMOS DE LA MISMA. SE EXTRAE UN RECUBRIMIENTO PROTECTOR 22 DE UNA ZONA EXTREMA DE POR LO MENOS OTRA FIBRA OPTICA 18. SE ENSARTA LA PARTE CUBIERTA DE LA PRIMERA FIBRA 17 A TRAVES DEL TUBO L0 HASTA QUE LA ZONA NO CUBIERTA DE LA MISMA ESTA CERCA DEL EXTREMO DEL TUBO. SE COLOCA LA PARTE NO CUBIERTA DE LA SEGUNDA FIBRA 18 JUNTO A LA DE LA PRIMERA FIBRA Y SE ALIMENTAN SIMULTANEAMENTE AMBAS ZONAS DENTRO DE LA ABERTURA DEL TUBO. DESPUES DE CONTINUAR LA OPERACION DE INSERCION HASTA QUE LAS ZONAS NO CUBIERTAS SE EXTIENDEN A TRAVES DE LA ZONA MEDIA 27 DEL TUBO 11, SE CALIENTA LA ZONA MEDIA PARA QUE COLAPSE ALREDEDOR DE LAS FIBRAS,Y SE ESTIRA LA PARTE CENTRAL DE LA ZONA MEDIA PARA REDUCIR EL DIAMETRO DE LA MISMA SEGUN UNA LONGITUD PREDETERMINADA.
