Abstract: A cable accommodating body includes one or more cable bundles made of a wound cable and not having any winding core and one or more first containers accommodating the one or more cable bundles and having a first outlet and a second outlet through each of which the wound cable is pulled out from an inside of the one or more first containers.

Abstract: A storage unit includes a wound body made of wound linear material and a storage body that stores the wound body. The wound body includes a first spiral part in which the wound linear material is spirally wound in a first winding direction such that a distance between the wound linear material of the first spiral part and a center of the wound body gradually decreases, a first inversion part, disposed inside the first spiral part, that inverts a winding direction of the wound linear material from the first winding direction to a second winding direction opposite to the first winding direction, and a second spiral part, disposed outside the first inversion part, in which the wound linear material is spirally wound in the second winding direction such that a distance between the wound linear material of the second spiral part and the center gradually increases.

Abstract: A bundling suspension wire includes: a suspension wire that includes a supporting wire and a coat coating the supporting wire; a hanger member that is suspended from the suspension wire and into which a cable is configured to be inserted; and wire threading cords that are inserted into the hanger member.

Abstract: A fixing structure includes: an optical fiber group constituted by a plurality of optical fibers; a tubular member through which the optical fiber group is passed; a reticulated tube, one end part of the reticulated tube being disposed on an outer periphery of the tubular member, the optical fiber group being inserted through an extended section of the reticulated tube extending out from the tubular member; and a fixing member that fixes the tubular member which has the reticulated tube disposed on the outer periphery thereof.

Abstract: An optical fiber protective unit includes: a reticulated tube; and a tubular member that is inserted through the reticulated tube and that is configured to accommodate a plurality of optical fibers. The reticulated tube is disposed on an outer periphery of the tubular member in a state folded in a longitudinal direction. Both end parts of the reticulated tube are located on the outer periphery of the tubular member.

Abstract: An optical fiber cable includes: a sheath including recesses and protrusions that are alternately disposed in a circumferential direction on an outer circumferential surface of the sheath; a core that includes optical fibers and is accommodated in the sheath; tensile strength members embedded in the sheath; and a ripcord that is embedded in the sheath. A marking portion protruding outward in a radial direction is disposed in the sheath. The ripcord is disposed between the marking portion and the core.

Abstract: An optical fiber cable includes: a sheath including recesses and protrusions that are alternately disposed in a circumferential direction on an outer circumferential surface of the sheath; a core that includes optical fibers and is accommodated in the sheath; and tensile strength members embedded in the sheath. The core is interposed between the tensile strength members in a transverse cross-sectional view. In the transverse cross-sectional view, the tensile strength members are embedded in portions of the sheath facing outward from the core in a first direction in which the two tensile strength members face each other in the transverse cross-sectional view.

Abstract: An optical cable wiring method, includes: installing a bundle of optical cables from a utility pole as a starting point of a first wiring path to a branch point on the first wiring path; dividing, at the branch point, the bundle of optical cables into a first group and a second group; installing one of the optical cables in the first group along the first wiring path ahead of the branch point; and installing one of the optical cables in the second group along a second wiring path branching from the first wiring path.

Abstract: A reticulated tube includes: a plurality of openings that are reticulately formed; peripheral parts that form the openings; and a branch part that is formed in a boundary of three or more openings. The branch part includes three or more peripheral parts extending from the branch part. The reticulated tube is configured to accommodate a plurality of optical fibers inserted through the reticulated tube. The peripheral parts are restricted by the branch part and are bendable.

Abstract: A method of exposing a core of an optical fiber cable that includes: a core including an optical fiber; a wrapping tube wrapping the core; a jacket housing the core and the wrapping tube; and a tension-resisting member of a Fiber Reinforced Plastic (FRP) embedded in the jacket, includes: making a cut in a circumferential direction in the jacket at a position closer to a first end portion of the optical fiber cable than to a second end portion of the optical fiber cable in a longitudinal direction; bending the optical fiber cable at a portion having the cut and fracturing the tension-resisting member; and removing a removal portion of the jacket that is disposed between the cut and the first end portion.

Abstract: An optical fiber cable includes: a core; an outer filling disposed outside the core; and a sheath that covers the core and the outer filling. The core includes: optical fibers; an inner filling; and a wrapping tube that wraps the optical fibers and the inner filling. The outer filling and the inner filling absorb water.
