Safe distance between high-voltage power lines and fiber optic cables

Home / Safe distance between high-voltage power lines and fiber optic cables

The National Electrical Code establishes specific minimum distances when communications cables must run near power and light circuits. Aerial Cable Installation Pathway Separation When placing, installing, or rearranging communication cables and service drops, including optical fiber, copper and coax, the proper clearance requirements must be maintained. 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.

What Distance is Safe?

It''s even more difficult to predict a safe distance from neighborhood power distribution lines — the type typically found on wooden poles. For example,
