Abstract
Patente de Invenção para <B>"MéTODO DE PRODUçãO DE FIBRAS óTICAS"<D>. Uma fibra ótica e método de produção, no qual a fibra ótica se alterna entre regiões tendo diâmetros diferentes ao longo de seu comprimento, no qual o índice de refração de referida peça bruta e os diâmetros de referida fibra são escolhidos para resultarem em uma fibra tendo regiões alternantes de dispersão positiva e negativa em um comprimento de onda que é maior do que 1480 nm, ainda preferivelmente tem uma dispersão de rede e inclinação de dispersão baixas. Um tal perfil preferido consiste de uma região de núcleo circundada por uma região de revestimento, referida região de núcleo compreendida de uma região de núcleo central que é dopada para cima com relação à referida região de revestimento, referida região de núcleo central circundada por uma região de fosso que é dopada para baixo com relação à referida região de revestimento, e referida região de fosso é circundada por uma região de anel anular que é dopada para cima com relação à referida região de revestimento.
