摘要： PROBLEM TO BE SOLVED: To provide a high density optical fiber cable which does not increase in loss and is excellent in mechanical characteristics by preventing an optical fiber in a slot groove from jumping out of the groove, during an impact test.SOLUTION: An optical fiber cable 1 includes a press winding tape 5 wound around the outer peripheral surface 4a of a slot core 4, so as to cover a slot groove 3 storing an optical fiber 2 and a sheath 6 covering the press winding tape 5 and the slot core 4. In the optical fiber cable 1, the press winding tape 5 is bonded to the outer peripheral surface 4a of the slot core 4. Since the press winding tape 5 is bonded to the slot core 4, the press winding tape 5 functions as a cover for the slot groove 3. Therefore, the optical fiber 2 can be prevented from jumping out of the slot groove 3, to prevent the optical fiber 2 from being pinched between the slot core 4 and the sheath 6.

摘要： PROBLEM TO BE SOLVED: To make highly efficient recycling possible by recovering component materials in a high purity condition from the waste materials of used optical cables. SOLUTION: The optical cable 1 is composed of an optical cable core 13, a sheath 15 covering the circumference of this optical cable core 13, and a rip cord 25 installed longitudinally inside the sheath 15. The rip cord 25 is a fibrous body 27 impregnated with a resin 29, suppressing fluffing of the fiber. Consequently, it prevents fusion/deposit of the fiber of the fibrous body 27 onto the inner surface of the sheath 15 of the optical cable 1, facilitating separation between the rip cord 25 and the sheath 15, and making possible the recovery of the sheath materials with high purity.

摘要： PROBLEM TO BE SOLVED: To provide a fiber optic cable which is suitable for the recycling of high purity sheath layers by composing the fiber optic cable so that a wrapping nonwoven fabric is prevented from mixing with the sheaths.
SOLUTION: In the fiber optic cable 10 suitable for the recycling, the slot body 13 with optical fibers 15 stored in optical fiber storing slots 14 is wound with the wrapping nonwoven fabric 16 on the outer circumference and is further covered, on top of the outer circumference, with a sheath made of an extrusion-formed plastic resin. The sheath is composed of a double layered structure consisting of an inner layer sheath 18 which covers the wrapping nonwoven fabric 16 and an outer layer sheath 20 which covers the inner layer sheath 18.

摘要： PROBLEM TO BE SOLVED: To manufacture an optical fiber cable in which a plurality of coated optical fibers are twisted around a high tensile strength body at a stable twisting pitch without being affected by the linear velocity of the line or the revolving speed of an oscillator.
SOLUTION: In the method for manufacturing the optical fiber cable 1, the twisting direction of a plurality of coated optical fibers 5 is freely changed clockwise or counterclockwise around the high tensile strength body 3 by using the oscillator 21. In this case, by a clamping device 23, the high tensile strength body 3 is clamped from the side in a passable manner, thereby restricting the turning of the high tensile strength body 3 caused by the twisting force of the coated optical fibers 5. Thus, the high tensile strength body 3 is prevented from turning together, which stabilizes the twisting pitch of the coated optical fibers 5.
