摘要： PROBLEM TO BE SOLVED: To provide a coated optical fiber, a coated optical fiber tape, and a discrimination method of coated optical fiber in which detection of leakage light is facilitated and in which detection sensitivity of core wire discriminating light is improved.
SOLUTION: Pigment particulates 7a having a refractive index different from that of the outer layer 7 coating material are added to the outer layer 7 of an optical fiber 3 having UV resin coated inner and outer layers 5, 7.. The optical fiber 3 when bent has the capability to reduce coupling loss of leakage light. In other words, by bending the optical fiber 3, test light is designed to be scattered without being totally reflected in the boundary between the optical fiber and the air layer. In addition, bending the optical fiber 3 using this characteristic improves the detection sensitivity of the discriminating light for the coated optical fiber.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber cable in which the degree of movement of strands of the optical fibers is reduced while improving the pulling out of the characteristics of the optical fiber cable.
SOLUTION: Twelve optical fiber strands 3-1 to 3-12 are prepared. Then, the optical fiber strands 3-1 to 3-12 are arranged in parallel to each other to form a face thereof. The face is sandwiched from the top and the bottom directions in a longitudinal direction by members 13 which have adhesive layers 33. Both tip parts of the members 13 are press-contacted to hermetically seal the optical fiber strands and the optical fiber strands are stored and arranged in a storage section 5 provided in a cable sheath 9. On the sheath 9, notched sections 11 having approximately V shapes are provided on the surface which is orthogonal to the longitudinal axis direction of the storage section 5 to indicate dividing locations and high-tensile bodies 7 are provided in the vicinity of the cross section tip parts of the storage section 5 of the sheath 9 to absorb tension along the extended direction of the cable. Thus, the optical fiber strands are easily taken out by tearing up the notched sections 11. Moreover, the degree of movement of the optical fiber strands that are hermetically sealed is reduced.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber cable capable of stabilizing the loss characteristics of the cable and raising the identification.
SOLUTION: The optical fiber cable is constituted by preparing 12 lines of optical fibers 3-1 to 3-12 and by longitudinally applying with adhesive 13, in which an adhesive layer 33 is provided on the surface on which these optical fibers 3-1 to 3-12 are arranged in parallel so as to hold the fibers in up and down directions and by arranging them so as to be housed in the housing part 5 provided in a cable sheath 9. In the cable sheath 9, roughly V-shaped notched parts 11 which indicate cleavage positions are established on a face orthogonal to the direction of the longitudinal axis of the housing part 5 and tension members 7 which absorb tension in the stretch direction of the cable are established near both ends of the cross-section of the housing part 5 of the cable sheath 9. As a result, since the fibers move only in one-dimensional direction, transmission loss can be reduced.

摘要： PROBLEM TO BE SOLVED: To easily and surely discriminate only a target cable among multiple cables, with less external bad effect applied to the cable. SOLUTION: A string length body 15 comprises a long tape 25, a plurality of RFIDs23 spaced on one side of the tape 25 in the length direction, and a spacer 29 which is pasted near the RFID23 to protect the RFID23 from an external force, being thicker than the RFID23. Since the RFID23 is protected with the spacer 29 being thicker than the RFID23 neat it, the mechanical strength of the string length body 15 is improved. Even if an external force is applied on the string length body 15, the spacer 29 absorbs the external force to prevent damage on the RFID23. A cable attached with the string length body 15 vertically is easily discriminated by the RFID23. COPYRIGHT: (C)2004,JPO&NCIPI
