  • Is it okay to lay fiber optic cables on power poles

    Is it okay to lay fiber optic cables on power poles

    Sufficient clearance must be maintained between fiber optic cables and electrical power cables on joint-use poles. 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. Fiber in a duct solutions have a major aesthetic. Recent electrocution deaths of two installers working with all-dielectric self-supporting (ADSS) cables on utility poles with a mixture of high-voltage and telecom cables have raised safety concerns for fiber installation.
