Abstract

PURPOSE:To ease the center alignment at the optical fiber connecting by producing the optical fiber which has the fiber strand of ferromagnetic material extending in the lengthwise direction in the position not directly relating to the optical transmission in the cross section. CONSTITUTION:Ferromagnetic material powder 18 of melting point about 1500 deg.C is packed in the composite pipe having a pipe 15 composed of quartz glass or the like of a refractive index n1 and melting point about 2000 deg.C on the inner side and a similar pipe 16 composed of refractive index n2 on the outer side. The bottom end of the pipe 17 is then heated by a heating means 19 and the inside of the pipe is evacuated from the top end, whereby spinning is done and the optical fiber having ferromagnetic material fiber strand in the center is formed. The optical fiber 10 thus made has an inside clad 12 and core 13 of ring form in section concentrically about the ferromagnetic material fiber strand 11. Hence, to butt and connect such optical fibers, a magentic field is so applied that the magnetic flux crosses the butted end faces, then the fiber strands are magnetized and become magnets of opposite polarities and therefore center alignment becomes easy. In addition, the adverse influence upon the optical transmission in the core is prevented by the internal clad layer.
