Abstract

Obtg. tube blanks used for drawing optical fibres in which a deposit of glass is formed at high temp. inside a silica tube by introducing volatile chemical components which decompose to give molten oxides which form the glass, characterised in that the form of the tube is preserved during the whole, the deposit exists by counteracting the phenomena producing deformation caused by its weight or by pressure from the gas from the heating jets using >=1 rollers, vanes etc. rubbing or rolling the outside of the tube in the heated region and maintaining a gaseous pressure difference between the inside and the outside of the tube, the pressure inside the tube being somewhat greater than that outside it. The dimensions of the tube link being kept uniform along the length of the tube, the optical fibres produced on drawing have consistent props. with the refractive index varying uniformly from the inside to the outside.
