Abstract

SE PRESENTA UN METODO PARA HACER UNA GRAN LONGITUD, TAL COMO 50 KM DE CABLE SUBMARINO DE FIBRA OPTICA, EN EL CUAL LAS FIBRAS RECUBIERTAS CON ACRILATO (5) SE GUIAN MEDIANTE UNA LAMINA FIJA (10) Y SE EMPOTRAN MEDIANTE UN TROQUEL FIJO CON FORMA DE TROMPETA (7) EN UN RECUBRIMIENTO (3) DE POLIMERO TERMOPLASTICO RELATIVAMENTE LIGERO (POR EJEMPLO HYTREL-RTM) CON UN ANGULO DE CAIDA 0. EL REVESTIMIENTO (3) SE ABLANDA MEDIANTE CALOR Y SE TRANSPORTA EN UN ALAMBRE (2). LAS FIBRAS PARCIALMENTE EMPOTRADAS SE ENCIERRAN EN UN SEGUNDO REVESTIMIENTO (12) DEL POLIMERO MEDIANTE EXPULSION CONVENCIONAL. EL ELEMENTO SE RECUBRE CON UN MATERIAL DE BLOQUEO DEL AGUA A MEDIDA QUE EL ELEMENTO SE ENCIERRA EN UN MIEMBRO DE REFUERZO TUBULAR QUE COMPRENDE UN TUBO CONDUCTIVO DE COBRE O ALUMINIO RODEADO POR DOS CAPAS (24,25) DE ALAMBRES DE ALTA RESISTENCIA A LA TENSION. UNA FUNDA DIELECTRICA, COMO POR EJEMPLO POLIETILENO NATURAL, SE EXPULSA SOBRE LOS ALAMBRES. LA ESTRUCTURA DEL CABLE LIMITA LA UNION DE LAS FIBRAS A POR EJEMPLO 0,6 M PARA QUE SE CONSIGAN PERDIDAS MUY BAJAS.
