Abstract

Patente de Invenção para: <B>"GUIA DE ONDA óTICA DE MODO SIMPLES"<D>. Uma fibra de guia de onda ótica de modo simples tendo um perfil de índice de refração compreendendo não menos do que quatro segmentos (16, 18, 20, 22), proporciona propriedades de guia de onda bem adequadas para sistemas de telecomunicação submarinos ou de arraste longo. O novo perfil de índice de refração é caracterizado por um segmento de núcleo tendo um índice de refração negativo, no qual, o índice de referência é aquele de sílica. Outra característica da invenção é uma camada de revestimento que contém dopante de aumento de índice de refração pelo menos na porção de revestimento adjacente ao segmento de núcleo mais externo.Invention Patent for: <B> "SIMPLE MODE WAVE GUIDE" <D>. A single-mode optical waveguide fiber having a refractive index profile comprising no less than four segments (16, 18, 20, 22), provides waveguide properties well suited for subsea or trailing telecommunication systems long. The new refractive index profile is characterized by a core segment having a negative refractive index, in which the reference index is that of silica. Another feature of the invention is a coating layer that contains refractive index increase doping at least in the coating portion adjacent to the outermost core segment.
