Abstract
A device and method for automatically fusing optical fibers by melting portions of the fibers by discharge heating. Two optical fibers to be joined are each held by a fiber supporting stand and fiber holding stand one said of which is movable along the axial direction of the fibers. The movable fiber holding stand is spring biased. Its various positions are determined by plural stops which may be retracted to allow the movable fiber holding stand to move under force of the spring. A micrometer head driven by an electric motor moves the movable fiber holding stand in the forward direction.
