Abstract

"PRé-FORMA EM FORMA DE HASTE PARA FABRICAçãO DE UMA FIBRA óPTICA A PARTIR DA MESMA, MéTODOS PARA FABRICAçãO DE UMA PRé-FORMA EM FORMA DE HASTE E PARA FABRICAçãO DE UMA FIBRA óPTICA, E, FIBRA óPTICA". A invenção atual refere-se a uma pré-forma na forma de haste para a fabricação de uma fibra óptica a partir da mesma, assim como a um método para fabricação da tal pré-forma na forma de haste. Além disso, a invenção atual refere-se a um método para fabricação de uma fibra óptica, onde uma extremidade da pré-forma na forma de haste é submetida a um tratamento térmico, após o que a extremidade assim amolecida da pré-forma na forma de haste é submetida a uma força de tração para fins de extração de uma fibra óptica da mesma.
