ABSTRACT:
A cylindrical split alignment sleeve of ceramic material has an axial slit and is used in an optical fiber connector for connecting optical fibers to each other. In order to establish the strength reliability of the split ceramic alignment sleeve, a predetermined stress is applied to it by a test procedure ensuring no damage to the sleeve. According to the invention, a test load is applied to the inner circumferential surface of the split ceramic alignment sleeve by a loading part which includes stationary and movable members having inclined slidable contact surfaces. The sleeve is applied onto the load part and the movable member is displaced to apply load to the sleeve. The magnitude of load can be detected by deformation of the loading part or by displacement of the movable member.
