Image Number 4 for United States Patent #5769698.
A fixture of disc-like form for holding connector mounted optical fiber ferrules. When the connector is attached to the fixture, the ends of the ferrule and fiber extend slightly beyond the plane of the bottom surface of the fixture so that the end surfaces may be polished by movement of the fixture over a sheet of polishing paper. The ferrule, and consequently the fiber, are rotationally locked to the fixture to prevent relative movement therebetween during the polishing operation by an element removably positionable in cooperative engagement with the disc. The element is rotationally locked to both the disc and the fiber optic connector.
