Abstract

"MéTODO DE PRODUçãO DE PRé-FORMA DE FIBRA óPTICA E PRé-FORMA DE FIBRA óPTICA E FIBRA óPTICA PRODUZIDAS COM O MéTODO". Um método de produzir com o processo de deformação, uma pré-forma de fibra óptica capaz de formar uma fibra óptica na qual um incremento em perda de transmissão devido à absorção de OH é reduzido, e uma pré-forma de fibra óptica e uma fibra óptica produzidas com o método. O método compreende reduzir a quantidade de substâncias que contêm átomo de hidrogênio em um tubo de vidro, vedar uma extremidade do tubo de vidro e deformar o tubo de vidro para obtenção de um corpo sólido. Um aspecto do método compreende aquecer o tubo de vidro a uma temperatura igual ou inferior a 550<198>C, vedar uma extremidade do tubo de vidro, e deformar o tubo de vidro para obter um corpo sólido. A pré-forma produzida com o método tem uma característica em que sua porção formada pela porção de interface no momento da deformação contém grupos OH em uma concentração de 100 ppb em peso ou menos. A fibra óptica produzida pelo estiramento da pré-forma tem uma característica em que sua perda originada de OH é inferior a 0,5 dB/km em um comprimento de onda de 1,38 <109>m.
