    • Armored fiber optic cables and methods for making are disclosed that include an armor layer generally surrounding a fiber optic cable that includes at least one optical waveguide and a cable jacket. The cable jacket has an outer diameter and armor layer has an inner surface, wherein a gap exists between the outer diameter of the cable jacket and the inner surface of the armor layer. The armored fiber optic cable further includes a centering element disposed in the gap between the fiber optic cable and the armor layer. The centering element generally inhibits the fiber optic cable from moving away from a middle of the armored fiber optic cable towards the inner surface of the armor layer during winding of the armored fiber optic cable, thereby inhibiting wavy armor and/or preserving the optical performance of the at least one optical waveguide.
    • 公开了装甲光纤电缆和制造方法,其包括通常围绕包括至少一个光波导和电缆护套的光纤电缆的铠装层。 电缆护套具有外径,并且护甲层具有内表面,其中在电缆护套的外径和护甲层的内表面之间存在间隙。 装甲光缆还包括设置在光纤电缆和铠装层之间的间隙中的定心元件。 定心元件通常在缠绕铠装光纤电缆期间阻止光纤电缆从铠装光纤电缆的中间向着装甲层的内表面移动,由此抑制波浪装甲和/或保持光纤性能 所述至少一个光波导。
