An optical fibre is manufactured by forming a layer of fused silica, which may or may not be doped, on the inner wall of a fused silica tube by producing a plasma in the reactant gases flowing through the tube. By this means a higher temperature can be maintained inside the tube than at the tubes outer wall. The plasma is produced at substantially atmospheric pressure. Cooling gas is passed along the outer wall of the tube.
