PCT No. PCT/GB89/00962 Sec. 371 Date Mar. 19, 1991 Sec. 102(e) Date Mar. 19, 1991 PCT Filed Aug. 18, 1989 PCT Pub. No. WO90/02314 PCT Pub. Date Mar. 8, 1990.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.
