PURPOSE:To reduce the effect of working accuracy, facilitate working and achieve the improvement in coupling efficiency by positioning optical fibers in two ways through intermeshing of the V-grooves and guide pins disposed in two vertical and lateral directions, aligning the same on one straight line and connecting the same. CONSTITUTION:With a plug 1, the fiber holder 5 having an optical fiber 7 in the internal center of its main body 3 is fixed by screws 6. The fiber holder 5 comprises opposing two blocks 14a, 14b, sandwiching spacers 15a, 15b of approximately the same thickness as that of the optical fiber 7 between these, bonding and positioning the fiber 7 in the center between these, forming a V groove 16 in one direction on the end faces of the blocks 14a, 14b and forming a V groove 17 in the direction orthogonal to the V groove 16 on the end faces of the spacers 15a, 15b as well. The V groove of the blocks 14a, 14b and the V groove of the spacers are integrated by means of bolts, etc., after which they are worked simultaneously with the same accuracy, thus they are made identical in pitch, etc. together with the accuracy. Thereby, the fibers may be butted and connected on one straight line with high accuracy. |
