Abstract

Un método para fabricar preformas de fibras ópticas de sílice, en dónde el material que tiene que formar el núcleo de la preforma contiene un óxido volátil y aparece como una capa de sílice dopado que recubre el ánima de un tubo de sílice, en dónde el ánima de todo el tubo con su recubrimiento primeramente se contrae y luego finalmente se flexibiliza atravesando repetidamente por una zona caliente a lo largo del tubo mientras que se gira éste alrededor de su eje, en dónde durante dicha contracción del ánima se mantiene una ligera sobrepresión en el ánima por una mezcla de gas que contiene oxígeno y un haluro y oxihaluro del elemento que tiene dicho óxido volátil, pasando dicha mezcla de haluros del óxido volátil a través del tubo, luego a través de un depósito y finalmente a través de una larga conducción no-constreñida cuya conductancia reológica sea lo suficientemente pequeña para proporcionar la sobrepresión necesaria dentro del tubo a fin de evitar la tendencia del tubo a aplastarse durante el encogimiento de su ánima, y en dónde la concentración del haluro u oxihaluro en relación al oxígeno es tal que compense al menos en parte las pérdidas del óxido volátil por volatilización durante el encogimiento del ánima.
