SOLUTION: The pipe cable 100 for air pressure feeding having a plurality of the pipes 120 for air pressure feeding is inverted in a collection direction of the pipes 120 for air pressure feeding at specified intervals and therefore the pipe cable with which the smooth insertion of the optical cable is possible can be obtained. Also, a pressure-feedable distance can be made longer and further the line speed during the pressure-feeding can be improved. Further, the improvement in leading workability in midway of the pipe cable is possible as well. COPYRIGHT: (C)2004,JPO&NCIPI

SOLUTION: The optical fiber cable 1 of a slot type which houses a plurality of coated optical fibers into a plurality of slot grooves 7 formed at a long-sized slot rod 3 is constituted by housing intersected inductive lines 23 composed of paired and twisted lines repeated with twisted parts and parallel parts at specified intervals and radio frequency identifications (RFIDs) 25 arrayed at specified intervals in synchronization with the positions of the parallel part of the intersected inductive lines 23 into one slot groove 7B among the plurality of the slot grooves 7 and securing the lines and the RFIDs into the slot grooves 7. The RFIDs 25 are arrayed at the specified intervals in the longitudinal direction of the cable 1 and can therefore be easily checked and the information of the cable of the RFIDs 25 can be easily identified by a reader/writer device. Also the RFIDs are synchronized with the parallel parts of the lines 23 and therefore writing signals are guided to the parallel parts by the lines 23 and are batchedly written in the respective RFIDs 25.

摘要： PROBLEM TO BE SOLVED: To prevent a tension member for an optical element from being buckled owing to its local curvature when a coated optical fiber is led out of an optical fiber cable.
SOLUTION: The optical fiber cable 1 comprises a long-sized optical element part 9 constituted by covering with a cable sheath 7 a coated optical fiber 3 and a pair of the tension members 5 for the optical element which are made of nonmetal of ≥0.6 mm in diameter and arranged on both sides of the coated optical fiber 3 in parallel across it. Notch parts 11 are disposed on the surface of the cable sheath 7 on both sides of the coated optical fiber 3 in a 2nd direction orthogonal to the 1st direction connecting the tension members 5 for the optical element. The mean value of the thickness of the cable sheath 7 at the shortest distance from cut tips of the notch parts 11 on both the sides to the border surfaces of the coated optical fiber 3 is in a range of 0.1 to 0.4 mm. Consequently, the tension members 5 for the optical element which are made of nonmetal are never buckled and the coated optical fiber is easily led out.

摘要： PROBLEM TO BE SOLVED: To provide a fiber optic cable which has a thin diameter and superior loss characteristics and constructibility and is stabilized in strain and loss characteristics when wound around a drum or bobbin.
SOLUTION: The fiber optic cable 1 comprises a long-sized optical element part 11 constituted by covering with a cable sheath 9 a coated optical fiber 3 composed of a plurality of or a single optical fiber put in a flatly-sectioned area F, an interposing body 5 formed of a heat-resisting plastic yarn, an organic fiber, or an inorganic fiber added along the length while surrounding the plurality of coated optical fibers 3 in the flatly-sectioned area F, and tensile strength bodies 7 for optical element which are arranged on both sides of the flatly-sectioned area F in parallel near by the length-directional sides of the area F. Further, notch parts 13 are formed on the surface of the cable sheath 9 on both the sides of the interposing body 5. The plurality of coated optical fibers 3 and the interposing body 5 expand along the length of the flatly-sectioned area F, so the coated optical fibers 3 can be prevented from finely curving when the cable 1 is wound around the drum.

摘要： PROBLEM TO BE SOLVED: To provide an optical drop cable capable of preventing water from infiltrating a housing part for housing coated optical fiber, and stabilizing an optical transmission characteristic.
SOLUTION: The optical drop cable comprises an optical fiber 11 consisting of a plurality of optical fibers or a single optical fiber, a housing part 3 for housing this optical fiber 11, tension members 5 arranged in parallel on both sides of the housing part 3, a cable sheath 7 made of a thermoplastic resin coating the housing part 3 and the tension members 5 in one body, and notched parts 9 of almost a V-shape provided on the cable sheath orthogonal to the positions of the tension member arrangement 5, and since water infiltrating can be prevented wherever the optical drop cable 1 may be cut off, by filling the air gap in the housing part 3 housing the optical fiber(s) with a filler 13, water run can be prevented in the housing part 3. As a result, it is possible to inhibit the optical transmission characteristic from being lowered.
