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

The minimum clearance required between the power secondary conductor and the fiber-optic cable in a cable span is crucial for ensuring safety and performance integrity. A clearance of 30 inches is specified to prevent any potential electrical interference and physical damage to the fiber optics, which could compromise their function.

The distance acts as a safety barrier, which helps mitigate risks associated with the transmission of electricity and the potential for electrical arcing or induction. This specific clearance is generally reinforced in installation guidelines and regulatory standards to ensure that the fiber-optic cables are not affected by nearby power lines, which can carry high voltage and pose hazards. Adequate clearance aids in protecting the delicate fiber-optic strands from environmental factors that might impact their operation, such as heat and electromagnetic fields generated by the power lines.
