Title
(EN) OPTICAL FIBER CABLE
(FR) CÂBLE À FIBRES OPTIQUES
(JA) 光ファイバケーブル
Abstract
(EN)
This optical fiber cable is provided with: a first unit in which a plurality of optical fiber tape core wires each having a plurality of optical fiber core wires arranged in parallel are bundled; and a slot rod having a plurality of lines of slot grooves, formed in a spiral shape, for accommodating the first unit, wherein the first unit is twisted along the longitudinal direction of the optical fiber cable in a state in which the optical fiber tape core wires are twisted back with each other, and the first unit is accommodated, in a twisted back state in the slot grooves, along the longitudinal direction of the optical fiber cable.
