What is the primary purpose of grounding to earth in fiber-optic installations?

The primary purpose of grounding to earth in fiber-optic installations is to protect against the adverse effects of lightning. Grounding serves as a safety measure, ensuring that any electrical surges caused by lightning strikes do not affect the fiber-optic equipment and systems. By providing a direct path for excess electricity to dissipate into the ground, grounding helps prevent damage to sensitive equipment and minimizes the risk of electrical shock to technicians working in the vicinity.

While ensuring a reliable communication link, enhancing data transmission speed, and improving signal strength are important aspects of fiber-optic systems, these factors are not directly related to the primary purpose of grounding. Grounding specifically addresses safety and protection from electrical disturbances, which is critical in maintaining the integrity and longevity of the infrastructure.
