Abstract

Método de fabricación, en un proceso continuo, de un paquete de fibras ópticas para instalación por soplado, que comprende las etapas de: (i) colocación de una pluralidad de fibras ópticas móviles (1) en una correlación espacial predeterminada; (ii) formación de un primer recubrimiento de resina (2) alrededor de la pluralidad de fibras ópticas móviles; (iii) vulcanizado de dicho primer recubrimiento de resina manteniendo al mismo tiempo la pluralidad de fibras móviles en dicha relación; (iv) formación de un recubrimiento de resina adicional (3) alrededor del recubrimiento vulcanizado formado en la etapa (iii); y (v) vulcanizado de dicho recubrimiento de resina adicional; caracterizado porque se prevé una etapa adicional, entre las etapas (iv) i (v), de modificación de la superficie de dicho recubrimiento de resina adicional añadiendo intencionadamente materia granulosa (4) a la superficie de la resina de forma que no exista una penetración importante de la materia granulosa en la interfasesituada entre los recubrimientos de resina primero y el adicional, no produciéndose por ello en dicha interfase ningún cambio permanente importante en el carácter del recubrimiento de resina adicional, conservándose la vulcanización de la etapa (v) que da como resultado dicha modicación de la superficie.
