Abstract

PURPOSE: To simplify production stages and to obtain ultra-multiple fiber optical fiber cables by forming housing lines adjacently to each other in such a manner that the V-shaped aperture of one line is covered with the V-shaped side wall of the other line. CONSTITUTION: Optical fibers 11 are housed in V-grooves formed by the V-shaped housing lines 12. The housing lines 12 are formed adjacent to each other in such a manner that the V-shaped apertures 12a are covered by the V-shaped side walls 12b of the adjacent V-shaped housing lines 12. The end face 12c of the side walls 12b of the one V-shaped housing line 12 is pressed in this state to both end parts 12d, 12e of the side walls 12b of the adjacent other housing line 12. The sections of the V-shaped housing lines 12 constitute an isosceles triangular shape of a vertex of 60 deg.. The outside shapes formed by pressing of the V-shaped housing grooves 12 to each other form the optical fiber cable 13 of a regular hexagonal shape if six pieces of the V-shaped housing grooves 12 are radially arranged.
