PURPOSE:To stabilize optical coupling between fibers by coupling and fixing optical fibers, which are cut by the insertion of an optical control member, by pipe-shaped glass which has an internal diameter a little larger than the external diameter of the optical fibers and an external diameter a little smaller than the internal diameter of a flange part. CONSTITUTION:The optical control member 36 is inserted into the flange part 32 and the fibers 33a and 34a which are cut by the insertion of the optical control member 36 are coupled and fixed by the pipe-shaped glass 38 which has the internal diameter a little larger than the external diameter of the fibers 33a and 34a and the external diameter a little smaller than the internal diameter of the flange part 32. Then the jackets of parts of the optical fibers 33 and 34 which are inserted into the glass pipe 38 and a fitting part 31 are removed to expose the fibers 33a and 34a themselves. Therefore, the optical fiber 33 has the optical fiber 33a exposed entirely, the optical fibers 33a and 34a in the glass pipe 38 are adhered by the glass fiber, and the part of the optical fiber 34 where its jacket is not removed is adhered to the flange part 32. Consequently, the stable connection terminal which is incorporated in the optically coupled optical control member can be realized. |
