A ferrule heating apparatus, which is configured to heat a ferrule and thereby adhere an optical fiber and the ferrule together, includes a plurality of ferrule housing portions capable of freely housing and aligning ferrules, a holdermade of a thermally conductive member, a holder heating unitfor supporting and heating the holder, and a temperature control unitfor controlling a temperature of the holder heating unit. The holder heating unitand the temperature control unitare provided mutually separately. Meanwhile, the holder heating unitand the temperature unitare mutually connected to each other through an electric power cable

Ferrule heating apparatus and method of adhering ferrule and optical fiber

The center of a turntable moves around the central axial line of an autoroation disk along the circular orbit C of a smaller diameter than that of an autorotation disk . Thus, the turntable revolves both around a center point O and on its own axis in accordance with an autorotation of the autorotation disk . A polishing holder holds a connector of an optical fiber polished by a polishing film arranged on the upper plane of the turntable . An optical fiber end face polishing machine provided with a memory for storing a control program which allows a control device to execute predetermined polishing steps, the control device being for controlling an autorotation motor of the turntable and a revolution motor thereof.
