Abstract

PURPOSE: To make adhesion of tape-form fibers to one another unnecessary by laminating the fibers in a tape whose section has been bent to U shape.
CONSTITUTION: A plurality of tape-form fibers 2 each composed of a plurality of optical fibers 1 arranged are laminated in tape 3 whose section has been bent to U shape, and another tape 4 whose section has also been bent to U shape is combind from the opposite side of tape 3. Thus, all of the optical fibers are contained in the space of a square section surrounded by tapes 3, 4. Tapes 3, 4 are spirally twisted in the longitudinal direction, and inner fibers 2 are also twisted in the same way. The outside of tapes 3, 4 is covered with tape wound layer 5 and sheath 6. A plurality of high tensile strength wires 7 may be arranged.
