Title (EN) CABLE AND METHOD FOR INTRODUCING INITIAL TENSILE STRAIN INTO OPTICAL FIBER
(FR) CÂBLE ET PROCÉDÉ D'INTRODUCTION D'UNE DÉFORMATION EN TRACTION INITIALE DANS UNE FIBRE OPTIQUE
(JA) ケーブル及び光ファイバへの初期引張歪の導入方法
Abstract:
(EN) A cable (10) is provided with: a cable body (11) comprising a plurality of wires (14) that are integrally bundled; and a pair of sockets (12) that are fixed to the respective ends of the cable body (11), wherein at least one of the plurality of wires (14) is a fiber-containing wire (16) obtained by securely housing in a protective tube (18) an optical fiber (17) extending in a cable length direction (D), and the optical fiber (17) extends out of the protective tube (18) along the cable length direction (D) beyond the sockets (12), and each of the pair of sockets (12) is provided with a spool (30) that detachably holds the optical fiber (17) so as to impart an initial tensile strain to the optical fiber (17).
(FR) L'invention concerne un câble (10) qui comprend : un corps de câble (11) comprenant une pluralité de fils (14) qui sont intégralement mis en faisceau ; et une paire de douilles (12) qui sont fixées aux extrémités respectives du corps de câble (11), au moins l'un de la pluralité de fils (14) est un fil contenant des fibres (16) obtenu en logeant de manière sûre dans un tube de protection (18) une fibre optique (17) s'étendant dans une direction de longueur de câble (D), et la fibre optique (17) s'étendant hors du tube de protection (18) le long de la direction de la longueur de câble (D) au-delà des douilles (12), et chacune de la paire de douilles (12) comprend une bobine (30) qui maintient de manière détachable la fibre optique (17) de manière à conférer une déformation en traction initiale à la fibre optique (17).
(JA) ケーブル(10)は、一体に束ねられた複数本の線材(14)により構成されるケーブル本体(11)と、ケーブル本体(11)の両端部が各別に固定された一対のソケット(12)と、を備え、複数本の線材(14)のうちの少なくとも一本は、ケーブル長さ方向(D)に延びる光ファイバ(17)が保護管(18)により保護されてなるファイバ内蔵線(16)とされたケーブル(10)であって、光ファイバ(17)は、保護管(18)からケーブル長さ方向(D)に沿ってソケット(12)よりも外側に向けて突出し、一対のソケット(12)にはそれぞれ、光ファイバ(17)を着脱可能に把持して光ファイバ(17)に初期引張歪を付与するスプール(30)が設けられている。
