The end of an optical fiber cable is mounted in a fixture that is mounted to ride on the surface of a polishing disk. The disk has a hole in a location to pass under the cable on each revolution. The hole is large enough to expose the end of the cable but is small enough to not interfere with the way the fixture rides on the disk. Light is applied to the remote end of the cable and shines through the hole in the disk. A light sensor is located below the disk to detect light from the fiber when the hole in the disk unmasks the end of the fiber. As the end of the fiber is polished, more light is transmitted through the fiber and is received by the detector.
