Abstract

METODO PARA PRODUCIR UNA PREFORMA DE VIDRIO PARA FIBRA OPTICA DE MODALIDAD UNICA. UN METODO PARA PRODUCIR UNA PREFORMA DE VIDRIO DESTINADA A LA FABRICACION DE UNA FIBRA OPTICA DE MODALIDAD UNICA, CARACTERIZADO PORQUE SE AÑADE UN COMPUESTO QUE CONTIENE FLUOR DURANTE LA HIDROLISIS POR LLAMA DE MATERIA PRIMA CONSTITUTIVA DE VIDRIO PARA CONSTITUIR LA PREFORMA DE NUCLEO POROSO, NO PRESENTANDO LA PREFORMA DE VIDRIO PRODUCIDA MEDIANTE LA MISMA NINGUNA IRREGULARIDAD DE INDICE DE REFRACCION EN LA PORCION DE REVESTIMIENTO, O SIENDO TAL IRREGULARIDAD PEQUEÑA.
