PURPOSE:To obtain efficiently optical fiber bundles which are arranged at a prescribed pitch by forming a magnetic material film on the outside circumferential surface at the forward end of each optical fiber, and sucking the forward ends of the optical fibers into a base plate which is disposed with guide spots magnetized in the direction reverse from the film at a specified pitch. CONSTITUTION:A magnetic material film 2 is formed on the outside circumferential surface at the forward end of an optical fiber 1 at about 1-10mu film thickness by dipping the forward end of the fiber 1 into a soln. of a polymer material dispersed therein with, for example, magnetic material powder, then pulling, drying and curing the same. The fibers 1 are arranged at a prescribed pitch by utilizing the inter-magnetic attraction force between the films 2 and a base plate 3 provided with guide spots 4 magnetized in the direction reverse from the film 2 in, for example, a matrix shape. The easy insertion of the fibers 1 to a perforated grid 5 at a specified pitch is made possible by the above-mentioned method. The bundles for optical image transmission having a high resolution, etc. are thus obtd. at pitch intervals with high accuracy and good productivity. |
