Underwater internet cables, also known as submarine communications cables, serve the purpose of connecting different and countries to establish global communication networks for internet and data transmission. These cables are laid on the ocean floor and facilitate the vast majority of international telecommunications, including internet, phone calls, and data transfer between countries. They are the backbone of international internet connectivity, allowing for the exchange of large volumes of data across long distances at high speeds. These cables support a wide range of applications, international business, e-commerce, social media, and more.

The key benefit of using underwater cables is their ability to provide high-speed, low-latency data transmission across vast distances, enabling seamless global communication and exchange. This method is more efficient and reliable compared to satellite communication over long distances, making it essential for global internet connectivity and international data exchange
