  • Can fiber optic cables be run over power poles

    Can fiber optic cables be run over power poles

    Sufficient clearance must be maintained between fiber optic cables and electrical power cables on joint-use poles. Existing dead-end pole must also be evaluated to determine their ability to withstand stresses during aerial cable installation. One way round this is to install aerial fiber cables close to power lines, such as on mixed use poles which also carry electricity. Obviously, these fiber cables need to be resistant to electricity, which can be difficult as many aerial cables contain high tensile steel (HTS) for tensile strength. Deploying fiber above ground on poles or towers removes the need for underground digging and is particularly useful when the ground is uneven, rocky or both. :) Otherwise they would have to dig a trench or use a trencher 1,200ft to our house or via the neighbor behind us.
