Here's how to safely move fiber optic cable: When moving fiber optic cable, follow these steps to ensure success: Planning: Assess the route carefully, noting any obstacles or sharp turns. Gather necessary equipment including proper rollers. Ensure that the work area is. bles in a high voltage environment, with typical line voltages of 115 kV or more, requires the evaluation of certain critical parameters. Curr ntly, there are a limited number of industry documents that address the requirements for optical fiber cables near high voltage circuits. How-ever, this is not enough if a. Fiber optic cables are sensitive to excessive pulling, bending, twisting, crushing and other impact forces, which may alter the fiber property and may pose threats to its performance. Most fiber optic cables boast a pull strength of 100 – 200.
