摘要： A method for producing an elongated optical fiber element is disclosed. The method envolves preparing two optical fiber elements by removing their outer coating layers to expose bare glass fiber portions. The glass fiber portions are melt-joint together. A material which is chemically compatible with the removed outered layer is then molded about the joined bare glass portions. A thermoplastic resin is then extruded continuously over the molded material in order to form a single elongated optical fiber element. The bonding method produces a structure which can withstand bending stress exerted on the coated optical fiber and prevent the concentration of any stress in the bonded area.

摘要： 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.
