METHOD AND APPARATUS FOR DRAWING AN OPTICAL FIBRE FROM A SOLID PREFORM MADE OF SIO2 AND DOPED SIO2 |
摘要 |
Optical fibres are drawn from a solid preform which consists substantially of SiO2 and doped SiO2. After leaving the heating zone, the fiber is guided through a space having a laminar gas flow to restrict the temperature drop across the fiber so that no extra stresses are incorporated in the fiber upon cooling. A device for performing this method comprises a quartz pipe through which the fiber is guided and in which a laminar gas flow is maintained. |
