They enable adds, moves, and changes without re‑pulling cable, allow recovery from connector damage through re‑termination, act as a buffer for bend‑radius and strain‑relief requirements (especially for fiber and shielded cable), and support inspection or troubleshooting. They enable adds, moves, and changes without re‑pulling cable, allow recovery from connector damage through re‑termination, act as a buffer for bend‑radius and strain‑relief requirements (especially for fiber and shielded cable), and support inspection or troubleshooting. Fiber optic cables are ordered in specific lengths as calculated by an OSP (Outside Plant) Engineer. Their lengths are determined by measuring the distance between splice manholes plus the excess cable length required for racking the cable at all manhole locations and slack storage for maintenance. To ensure all specifications are met, consult the specific cable specification sheet for the cable you. However, fiber optic cable is a high capacity transmission medium which can have its transmission characteristics degraded when subjected to excessive pulling force, sharp bends, and crushing forces. These losses may not be revealed until long after installation is complete. For these reasons extra. Placing Fiber Optic Cable in Underground Plant 1. In some applications, the innerduct may be lashed to an aerial strand.
