Abstract

"PRé-FORMA DE FIBRA óTICA COM BARREIRA DE OH E SEU MéTODO DE FABRICAçãO". Uma pré-forma de fibra ótica e um método de fabricação da mesma. Na presente invenção, uma barreira de OH externa e uma barreira de OH interna isentas de P~ 2~O~ 5~ são depositadas respectivamente entre um tubo de substrato e uma camada de revestimento e entre a camada de revestimento e uma camada de núcleo durante um processo de deposição. Além disso, um índice de refração aumenta na direção do centro da camada de núcleo.
