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 device that pulls out an optical fiber includes: a bobbin support that supports a bobbin rotatably about a rotation axis; a first pulling out unit that holds a first end of the optical fiber, pulls out a first portion of the optical fiber wound around the bobbin from a side of the first end in a state where the bobbin rotates in a predetermined direction, and returns a part of the first portion to the bobbin in a state where the bobbin rotates in a direction opposite to the predetermined direction; and a second pulling out unit that holds a second end of the optical fiber after the first pulling out unit pulls out the first portion from the side of the first end, and pulls out a second portion of the optical fiber wound around the bobbin from a side of the second end.

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: An inspection device of an optical fiber unit, including a plurality of binding materials wound in an SZ shape on a plurality of optical fibers, includes: a measurement sensor that measures a width of the optical fiber units in a first direction orthogonal to a longitudinal direction in which the optical fiber unit extends; and a determination circuit that determines a presence or an absence of an abnormality in a binding state, based on a measurement result of the measurement sensor.
