Abstract
【解決手段】光ファイバ配線ケーブル(30)は、1本又は2本以上の光ファイバを加入者に向かって配線するために1本又は2本以上の光ファイバ(32)を保護被覆材の外方に導出する。配線ケーブルから取り出され、保護被覆材の外部に導出された1本の配線用光ファイバは、アクセス場所(AL)のところの開口部よりも長い。別の実施形態では、配線ケーブルに出入りする配線用光ファイバの運動(即ち、ピストン運動)を阻止する区間点が設けられる。さらに別の実施形態では、割送りチューブ(150)が設けられ、この割送りチューブは、テザーチューブ(140)を割送りチューブ内で割り送って配線用光ファイバに適当な過剰ファイバ長さを与える。
