OPTICAL FIBER SUPPORTING DEVICE

PURPOSE:To connect simultaneously, surely and collectively plural optical fibers in parallel by embedding and fixing optical fibers held on respective prescribed positions except both the end parts in a solid member. CONSTITUTION:A fiber supporting device is obtained by arranging and temporarily fixing respective optical fibers in respective required relative positions, surrounding them by a metal frame, surrounding the periphery by thermosetting resin having fluidity and then molding and setting the whole. The length of the optical fibers projected from the solid member 2 may be 4-5 times the diameter of each optical fiber and too long length may be influenced by vibration or curve. Respective constitutional parts are rigidly fixed on a printed circuit board 7 by respective connection layers 8-10. The positioning of the optical fiber group 1 to plural light emitting and receiving parts 4, 6 can be executed by finely adjusting the solid member 2 by a normal manipulator and respective constitutional parts are fixed on the printed circuit board 7 semipermanently through an adhesive layer 9 such as soldering at the positions for providing required optical coupling efficiency.
