Abstract

"PROCESSO E APARELHO PARA PRODUZIR UMA FIBRA óTICA DE BAIXA PMD, CABO óTICO, E, FIBRA óTICA". Um aparelho para produzir uma fibra ótica de baixa PMD, compreendendo um forno (6) para fundir uma parte inferior de uma preforma ótica (3); um dispositivo de tração (8) para puxar uma fibra ótica (4) de dita parte inferior de uma preforma ótica; um dispositivo de rotação (20) para dar uma rotação substancialmente constante e unidirecional às fibras óticas quando elas são puxadas, o que faz com que a fibra sofra uma torcedura elástica; um dispositivo de enrolar (9) para enrolar a fibra ótica em um carretel (10); e um dispositivo de torcedura (40) para dar à fibra ótica girada uma torção unidirecional em uma direção oposta a dita torcedura elástica, de modo a controlar a torção residual da fibra ótica. Um processo para produzir a fibra, a fibra ótica e um cabo compreendendo a fibra ótica são também reivindicados.
