    • Assemblies and methods for installing and maintaining aerial fiber optic cable are provided. Embodiments include a cable long enough to extend from two elevated support points and to provide enough slack for at least a portion of the cable to extend along the ground. The cable includes a wrapped portion for storing the slack and to elevate the entire cable above the ground. The wrapped portion being releasable in response to a force acting on the cable, such as a falling tree, allowing for at least a portion of the cable to fall to the ground and minimize the likelihood of the tree snapping the cable. Fasteners and frame members may be employed to support the wrapped portion. An embodiment may also include a cut-off apparatus for cutting the cable in response to the cable being pulled further once any slack in the cable has been expended.
    • 提供了安装和维护空中光纤电缆的组件和方法。 实施例包括长度足以从两个升高的支撑点延伸的电缆并且为电缆的至少一部分沿着地面延伸提供足够的松弛。 电缆包括用于存放松弛的包裹部分,并将整个电缆提升到地面上方。 包裹的部分可响应于作用在电缆上的力(例如落下的树)而释放,允许电缆的至少一部分落到地面上,并使树的电缆的可能性最小化。 紧固件和框架构件可用于支撑包裹部分。 一个实施例还可以包括一种切断装置,用于在电缆中的任何松弛已经消耗之后响应于电缆被进一步拉动来切割电缆。
