摘要： Provided is an optical fiber cable including a sheath, a core accommodated in the sheath, and at least two tensile strength members embedded in the sheath so as to interpose the core therebetween in a transverse cross-sectional view. A plurality of protrusions and a plurality of recesses alternately disposed in a circumferential direction are formed on an outer circumferential surface of the sheath. In the transverse cross-sectional view, when a direction in which the two tensile strength members face each other is a first direction, the tensile strength members are embedded only in portions of the sheath facing outward from the core in the first direction.

摘要： Optical fibers 3-1 to 3-8 are aligned in a row, and buffer tapes 13 are longitudinally attached to a top surface and an undersurface so as to sandwich the optical fibers 3-1 to 3-8. The optical fibers 3-1 to 3-8 and the buffer tapes 13 are housed in a hollow portion 5 provided in a cable sheath 9. Substantially V-shaped notches 11 for indicating a splitting position are provided on planes of the cable sheath 9 parallel to the longitudinal direction of the hollow portion 5. Strength members 7 for absorbing tension in a tensile direction of the cable are provided in the vicinities of both ends of the hollow portion 5 of the cable sheath 9. Since the optical fibers 3-1 to 3-8 can only move one-dimensionally, it is possible to reduce transmission losses.

摘要： To provide a novel method for winding a linear material. A housing unit according to the present disclosure includes a linear material and a housing body configured to house the linear material. In the housing body, a plurality of winding regions in which the linear material is wound are located in a circumferential direction. The linear material is wound in a figure eight in a first region pair constituted by a pair of winding regions. The linear material is wound in a figure eight also in a second region pair constituted by a pair of winding regions that are a combination of winding regions differing from the winding regions constituting the first region pair.

摘要： A management device according to the present disclosure manages a unit in which a long object is wound around a drum. The management device determines the remaining amount of the long object based on a matching result found by matching: matching data obtained by associating an image capture result obtained by successively capturing images of the unit while winding the long object around the drum, and a winding amount of the long object wound around the drum at the time of image capturing; and an image capture result of the unit acquired from a user terminal.
