PCT No. PCT/GB85/00053 Sec. 371 Date Nov. 25, 1985 Sec. 102(e) Date Nov. 25, 1985 PCT Filed Feb. 8, 1985 PCT Pub. No. WO85/03502 PCT Pub. Date Aug. 15, 1985.Apparatus for cleaving an optical fibre (115) under axial tension, is provided with a cleaver blade (116) which is mounted as part of a rotatable cleaver assembly. The assembly is balanced about its axis of rotation and, as described, comprises a wheel (117) mounted on an axle (138). The cleaver blade (116) is attached to an arm which extends radially from the wheel (117). A hair spring (304) drives the assembly. The cleaving apparatus finds particular application in cleaving monomode fibres under normal working, rather than laboratory, conditions.
