When should grounding clamps be installed on aerial fiber-optic cables?

Grounding clamps should be installed on aerial fiber-optic cables at every pole site to ensure safety and functionality. This practice is crucial because it helps to manage electrical surges caused by lightning strikes or other electrical interference, thereby protecting the delicate fiber-optic equipment and maintaining a reliable communication system.

Installing grounding clamps at every pole creates a continuous grounding path, reducing the risk of damage due to electrical faults. It also ensures that any induced voltages are effectively dissipated into the ground, enhancing the overall integrity of the fiber-optic network. Having grounding clamps at every pole site means that the system can handle local spikes effectively, which is essential for preventing equipment failure and maintaining service quality.

While grounding at the beginning and end of spans or during installation might seem convenient, these methods do not provide adequate protection for the entire span of cable, particularly since environmental conditions can vary significantly along the route. Regular monthly checks are also insufficient because grounding clamps should be in place all the time to provide ongoing protection. Thus, the installation of grounding clamps at every pole site is the most effective approach for safeguarding aerial fiber-optic cables.
