Abstract

EL CABLE DE FIBRA OPTICA DE CINTA DESCRITO, COMPRENDE UN NUCLEO CILINDRICO (9) PROVISTO, EN SU SUPERFICIE EXTERNA, CON ESTRIAS PARALELAS (10) QUE SE EXTIENDE DE FORMA HELICOIDAL A LO LARGO DEL EJE DEL CABLE, ESTANDO AL MENOS UN PAR DE CINTAS (1) SUPERPUESTAS RADIALMENTE DENTRO DE AL MENOS UNA DE DICHAS ESTRIAS (10). CADA CINTA (1A, 1B, 1C, 1D, 1E) COMPRENDE UNA PLURALIDAD DE FIBRAS OPTICAS (2) CADA UNA DE LAS CUALES ESTA CUBIERTA CON UN RECUBRIMIENTO EN CAPAS PRIMARIO (3), Y UN RECUBRIMIENTO COMUN (4) CUBRE TODAS LAS FIBRAS OPTICAS DE LA CINTA. EL RECUBRIMIENTO PRIMARIO (3) ESTA FORMADO CON UNA PRIMERA CAPA (5) DIRECTAMENTE EN CONTACTO CON LAS FIBRAS (2) Y UNA SEGUNDA CAPA (6) EXTERNA A LA PRIMERA CAPA (5), SIENDO EL MODULO DE ELASTICIDAD DE DICHA PRIMERA CAPA (5) INFERIOR QUE EL MODULO DE ELASTICIDAD DE DICHA SEGUNDA CAPA (6). APLICADA A CADA CINTA (1A, 1B, 1C, 1D, 1E) HAY UNA TENSION LONGITUDINAL MAYOR QUE LA TENSION LONGITUDINAL APLICADA A LA CINTA CUBRIENDO RADIALMENTE LA ANTERIOR. EL PROCESO PARA LA FABRICACION DE ESTE CABLE DE FIBRA OPTICA DE CINTA PROPORCIONA A LAS CINTAS (1) COLOCADAS EN LAS ESTRIAS, APLICANDO A CADA CINTA (1A, 1B, 1C, 1D, 1E) UNA TENSION LONGITUDINAL MAYOR QUE LA TENSION LONGITUDINAL APLICADA A LA CINTA RADIALMENTE SUPERPUESTA A ELLA.
