High-voltage AC power lines generate fluctuating magnetic fields. When a communications cable runs parallel and in close proximity to a power cable, these magnetic fields induce unwanted currents—a phenomenon known as inductive coupling—into the sensitive data conductors. Curr ntly, there are a limited number of industry documents that address the requirements for optical fiber cables near high voltage circuits. This practice is mandatory for two distinct reasons: ensuring the safety of the structure and its occupants, and preserving the integrity of sensitive data. Running signal cables near high-voltage equipment typically results in the following consequences: Electromagnetic Interference (EMI): High-voltage equipment generates strong electromagnetic fields, especially during switching or transient events.
