Abstract: In order to eliminate the effect of water attack on silica optical fibres, the fibres are provided with a surface layer of silicon nitride or silicon oxynitride. The method proposed comprises direct nitridation. This may be achieved by adding a nitriding atmosphere to the drawing furnace gases, or to the reactive gases (TiCl4 and SiCl4) incorporated in the flame of an oxyhydrogen torch for the formation of a compressive silica/titania layer on an optical fibre by a glass soot deposition and sintering process.

The method proposed comprises direct nitridation. This may be achieved by adding a nitriding atmosphere to the drawing furnace gases, or to the reactive gases (TiCl4 and SiCl4) incorporated in the flame of an oxyhydrogen torch for the formation of a compressive silica-titania layer on an optical fibre by a glass soot deposition and sintering process.

Abstract: A coating material is applied to drawn lightguide fibre (36') by an applicator (6) which tilts about x and y axes under the control of a concentricity monitor (7) to maintain the coating of the coated fibre (36) concentric about the fibre.
