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.
