Abstract

Se divulga un aparato y método para la fabricacion de preformas de fibra optica donde los procesos de contraccion y cierre de un tubo depositados serealizan utilizando un dispositivo adecuado para esos procesos, dispositivo éste que es diferente deldispositivo usado en un proceso de deposicion para formarun tubo depositado sobre la superficie interior de un tubo preformado, con lo que se reduce el tiempo de procesamiento a la vez que se reduce la cantidad de OHque penetra desde el tubopreforma do hacia un componente vítreo del tubo depositado, lográndose de este modo una reduccion de la pérdida de OH. De acuerdo conel aparato y método para la fabricacion de preformas de fibraoptica, se realizan operaciones que involucranestablecer la temp eratura de caldeo de uncalefactor circular a una temperatura más baja que el punto de ablandamiento de un tubo depositado, exhausta los contaminantes existentes en el interior deltubo depositado a la vez que el calentador circularse mueve a una temp eratura deseada, establecer la temperatura de caldeo del calentador circular a unatemperatura que no sea más baja que el punto de ablandamiento del tubo depositado, y contraer y cerrar el tubo depositado a la vez que elcalentador circularse mueve a la temperatura deseada.
