IPC: G02B6/24
Filed: 1982-04-02
Abstract: PURPOSE:To align the axes of optical fibers, by applying elastic deformation to beams placed thereon with a pair of optical fibers to be aligned axially thereby applying the displacement to the optical fiber. CONSTITUTION:The length l from a point of application up to the bottom surface of supporting columns 2, 3 is so set that the columns do not deflect largely even if external force W2 is exerted at the forward ends of beams 4, 4 to be placed thereon with fibers. Thus, the displacement only in the x-axis direction is obtained by the external force W2 in the y-axis direction, while the displacement in the x-axis direction is developed distinctly by the external force W1 in the x-axis direction. When th point of application of the external force W1 to be exerted in the x-axis direction is selected at the point P2 located near the corner angle part in the upper part of the columns 3, 3, the forware end O of V-grooves 5, 5 displaces to O', but optical fibers f, f' slip merely on the beams 4, 4; therefore, the displacement in the z-axis direction is not generated in the fibers f, f', Thus, the displacement in the biaxial directions are applied to the optical fibers by exerting the external force on the beam 4, 4 and the columns 3, 3 in the above-mentioned way, whereby the optical fibers are aligned exactly axially without any alignment errors even if the end face of said fibers have a cutting angle, hence the loss of connection is decreased.
