Submarine fiber optic cables are vital for global connectivity as they provide high-capacity communication channels under the sea with minimal latency and reliable transmission. Fiber optics enable faster data transfer rates and better reliability than traditional cables. While submarine cables face challenges from fishing and environmental factors, their installation requires precise navigation and monitoring during deployment to lay the cable safely along major routes connecting the world.
