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

• A. To ensure data transmission efficiency
• B. To prevent water damage to cables
• C. To protect against lightning and reduce static
• D. To improve signal strength over longer distances

Answer: (C)

The primary purpose of grounding fiber-optic cables to earth is to protect against lightning and reduce static. Grounding provides a safe path for electrical surges—such as those caused by lightning strikes or static discharge—allowing them to ground safely and preventing damage to the fiber-optic equipment and the infrastructure surrounding it. This is particularly important in outdoor installations, where exposure to the elements increases the risk of such electrical events. Grounding helps maintain the integrity of the data being transmitted by ensuring that the fiber-optic system operates in a stable electromagnetic environment. By dissipating excess energy from surges, grounding safeguards sensitive equipment from potential harm that could disrupt service or lead to costly repairs. In contrast, ensuring data transmission efficiency, preventing water damage, and improving signal strength over longer distances do not primarily involve grounding practices. While these factors are important considerations in the installation and maintenance of fiber-optic systems, they do not address the electrical safety aspect that grounding performs, which is crucial for protecting equipment and ensuring reliable operation.
