PURPOSE:To produce an accurate optical connector with simple working, by protruding an optical fiber through a groove provided at the tip part of an optical fiber holder and forming the tip of the optical fiber into a spherical shape by fusing the tip with discharging or the optical energy. CONSTITUTION:A groove 12b is formed on the end face 12a of an optical fiber holder 12, and an optical fiber 10 is protruded through the center hole 12c. In this case, the protruding height is decided precisely. Then the protruded part is fused with an arc electrode or a laser light (not shown in the figure), and a spherical end 13 is formed by the surface tension. As the fiber 10 is thin, the tip of the fiber 10 is formed into a pure sphere. This sphere 13 is fixed with a gap K by a holding tool (not shown in the figure). The optical signals are diffused slowly at a terminal 10a and turned as shown dotted lines 15 at the part of the sphere 13. These signals are converged at a counter sphere part 13', and therefore the coincidence is tolerant to some extent between the axial cores of optical fibers. This can facilitate an automatic production with simple working, and both quality and reliability are stabilized. |
