Professional Answer: The use of OPGW offers several significant advantages:

• Dual Functionality: It combines grounding and high-speed communication into a single cable, reducing the need for separate infrastructure and installation costs.

• Enhanced Reliability: The embedded optical fibers are immune to electromagnetic interference, ensuring stable and secure communication.

• Improved Grid Management: OPGW enables real-time monitoring of power lines, allowing for quicker fault detection, load management, and overall system optimization.

• High Durability: Designed to withstand harsh environmental conditions, OPGW cables have a long service life and high tensile strength to handle wind and ice loads.

• Cost-Effectiveness: Although the initial investment might be higher, the long-term benefits of combining two systems into one, along with reduced maintenance, make it a cost-effective solution.
