    • A conductor has a layer (55) of helically wound metal elements around a central bore (56) loosely housing an optical fiber element (11) which has a flexible tube holding one or more optical fibers. The tube is resiliently set to an extended path so that it tends to straighten lengthwise when placed under tension. The tube may be set to smoothly curved undulations or to a helix with the lay 5-15 deg. to the central axis. The tube cross-section pref. has two parallel sides joined by semicircular end curves. The tube is pref. of orientated polyethyleneterephthalate, polyethersulphone or polyetherimide, with elongate reinforcing elements in the wall and each resiliently set, or is or resilient metal or alloy. The tube may be filled with e.g. silicond gel.

    • A flexible tube has a bore in which at least one optical fibre is loosely housed. The tube is resiliently set in such a form that it follows a longitudinally extending path which is greater in length than the rectilinear distance between the two positions. When the resiliently set tube is subjected to a longitudinally applied tensile force, the tube will tend to straighten in a lengthwise direction against the action of its resilient set to reduce the tensile force applied to the or each optical fibre. When the tensile force is removed, the tube will return under the action of its resilient set towards its original form. The tube is in the form of a helical path, the lay of the helically extending path lying in the range 5 to 15 deg. to the central rectilinear axis of the helically extending tube.
    • 柔性管具有孔,其中至少一根光纤被松动地容纳。 管被弹性地设置成这样的形式,使得它遵循长度比两个位置之间的直线距离更长的纵向延伸路径。 当弹性固定管受到纵向施加的张力时,管将倾向于抵抗其弹性组的作用沿长度方向拉直,以减小施加到或每个光纤的张力。 当拉力被去除时,管将在其弹性套件的作用下返回其原始形式。 管呈螺旋形路径的形式,螺旋延伸路径的铺设位于5至15度的范围内。 到螺旋形延伸管的中心直线轴线。
