Abstract

"MéTODOS PARA FABRICAR UMA FIBRA óTICA E UMA PRé-FORMA DE FIBRA óTICA". Um método para fabricar uma fibra ótica incluindo prover uma porção com maior diâmetro (32) sobre uma haste (30). A haste é montada (12) pelo posicionamento da haste em um tubo (34) de modo que um vão anular (37) seja definido entre uma superfície externa da haste e uma superfície interna do tubo, e de modo que a porção com maior diâmetro da haste encaixe o tubo e suporte a haste com respeito ao tubo, e suporte a montagem de haste e tubo pelo agarramento do tubo. Na extremidade inferior da montagem de haste e tubo, porções do tubo são colapsadas sobre a haste, de modo que as porções de tubo se fundam com a haste, formando porções colapsadas da montagem de haste e tubo. As porções colapsadas são estiradas para formar uma fibra ótica, a montagem de haste e tubo orientada verticalmente podendo ser também colapsada para formar uma pré-forma de fibra ótica.
