Abstract
A method and apparartus for setting the orientation of an optical fibre (6) having at least one planar section extending along its length comprises a light source (3) for generating a beam of light which impinges on the fibre (6). Light reflected by the fibre is detected by a light detector (5) and the fibre is rotated by means of a tube (1) into which it is inserted while the intensity of the detected light is monitored. When the intensity becomes a maximum then the planar face is facing in a known direction.
