Abstract
An apparatus for simultaneously or selectively grinding ends of a plurality of optical fibers held by optical fiber end devices such as connectors including ferrules. The apparatus has a holder plate having a plurality of types of supporting structures for fixing and supporting a plurality of types of optical fiber end devices with optical fibers connected thereto. Spring or weights are used for urging ends of the optical fibers on the optical fiber end devices supported by the supporting structures. A circular-path-based relative motion is caused to occur between the holder plate and the grinding plate. Each of the optical fiber end devices is a connector including a ferrule. In such a case, the plurality of types of optical fiber end devices may be connectors whose end surfaces are to be ground at different angles or may be the connectors of different connection types. The circular-path-based relative movement has a rotation component which is rotation of the holder plate about its own axis and a revolution movement which is revolution of the axis of the holder plate. The supporting structures of each type are preferably arranged on a circle concentric with the axis of the holder plate and preferably at a constant angular interval.
