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.
