What is the minimum clearance needed between the power's secondary conductor and a fiber-optic cable in a cable span?

The minimum clearance needed between a power's secondary conductor and a fiber-optic cable in a cable span is 30 inches. This standard is essential for ensuring safety and preventing electromagnetic interference. Maintaining this distance helps to protect the fiber-optic cable from potential damage caused by electrical faults, heat, or physical stress that could occur with closer proximity to power conductors.

Fiber-optic cables are designed to transmit data using light, and their performance can be affected by external electrical fields. The specified clearance minimizes the risk of signal degradation, enhances the reliability of the fiber-optic communication, and ensures compliance with industry safety standards. By adhering to this clearance requirement, installers can help to safeguard the integrity of the fiber-optic system while maintaining the efficiency of electrical distribution in the area.
