Abstract: An optical fibre (1) is provided with a coating (2) which varies in thickness along its length, for use, for example, in optical fibre sensor systems, by applying layer of liquid coating material, and permitting surface tension to cause beading of the coating on the fibre before curing the coating material whereby to maintain the beaded structure.

Abstract: An induction furnace for drawing glass optical fibres from a preform has a R.F. powdered (7) susceptor element comprising a zirconia ring (1) within which the work if heated, located end wise between upper and lower rings (3), e.g. of silica, silicon carbide, alumina, titania, the zirconia ring (1) along its entire length reaching temperatures above any phase change so that the preform and fibre are not contaminated by zirconia particles. The three rings are located inside a tubular-zirconia support 4 and a silica "can" 6.

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.
