Abstract

"CABO óPTICO PARA TELECOMUNICAçõES, MéTODO PARA CONFECCIONAR UM CABO óPTICO PARA TELECOMUNICAçõES, FIBRA óPTICA ADEQUADA PARA USO EM UM CABO óPTICO, E, MéTODO PARA CONFECCIONAR A MESMA". Um cabo óptico (1) para telecomunicações compreende um núcleo óptico (2) e diversos elementos ou camadas de proteção e reforço (7, 11 e 13) colocados em torno do núcleo óptico, o núcleo óptico (2) compreendendo, por sua vez um elemento de reforço central (4), uma camada de polímero (5), diversas fibras ópticas (3) incorporadas na camada de polímero (5) e um revestimento fino (6) que cobre a camada de polímero (5), as fibras ópticas possuindo uma rotação alternada em relação a seus próprios eixos, com um valor máximo de pelo menos 4 torções por metro, e compreendendo um núcleo (12) possuindo uma elipticidade média na faixa de 0,25 a 0,55, de tal modo que os efeitos de birrefringência das fibras causados pelo processo de cabeamento são significativamente reduzidos.
