Underwater cables are specialized cables that are laid on the ocean floor to transmit data and electricity between different locations. These cables are essential for global communication, as they carry internet traffic and connect continents. They are made of durable materials to withstand harsh underwater conditions and are often buried to protect them from damage. In addition to data transmission, some underwater cables are designed to carry electricity, linking power grids across regions. The installation of these cables involves advanced technology and careful planning to ensure they are placed securely and efficiently, minimizing environmental impact and disruption to marine life.
