摘要： A ferrule heating apparatus 1, 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 27, a holder 5 made of a thermally conductive member, a holder heating unit 9 for supporting and heating the holder 5, and a temperature control unit 11 for controlling a temperature of the holder heating unit 9. The holder heating unit 9 and the temperature control unit 11 are provided mutually separately. Meanwhile, the holder heating unit 9 and the temperature unit 11 are mutually connected to each other through an electric power cable 13.

摘要： A silica-based glass rod is inserted into a space portion of a mold. Then, a slurry, which is obtained by dispersing a silica glass powder material in pure water, is poured into a molding space between the glass rod and the inner surface of the mold, whereby a porous glass shaped body is formed around the glass rod. Drying this shaped body results in a silica glass base material which includes the glass rod and the porous glass shaped body surrounding the same.

摘要： An extruding apparatus having at least two independent inlet ports, one outlet port communicating with the inlet ports, and at least two passages connecting the inlet ports with the outlet port, in which a section of a joint portion of the passages has a central portion and an outer peripheral portion which are concentrically arranged, is prepared. A core material is supplied to one of the passages communicating with the central portion of the joint portion from a corresponding inlet port, and a cladding material is supplied to the other passage communicating with the outer peripheral portion from a corresponding inlet port, thereby causing the two materials to join each other at the joint portion. An integral shaped body having a portion corresponding to a core at its central portion and a portion corresponding to a cladding around the central portion is extruded from the outlet port. Water and a binder and other impurities are removed from the shaped body, and the resultant body is consolidated.

摘要： A method for manufacturing a preform having steps of obtaining a plastic material by kneading silica powder, a binder, water, and a surfactant, and obtaining a porous preform by extrusion-molding the plastic material. According to this method, a porous preform, which can produce an optical fiber exerting high mechanical strength, can be efficiently manufactured without generating bubbles
