Abstract
Optical fibres are drawn from a solid preform which consists substantially of SiO.sub.2 and doped SiO.sub.2. 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.
