An undersea cable is a type of telecommunications cable that is laid on the seabed between land-based stations. These cables are essential for transmitting internet data, telephone calls, and television signals across long distances. They connect different continents and countries, enabling global communication and data exchange. Undersea cables are typically made of fiber optic technology, which allows for high-speed data transmission. They are designed to withstand harsh underwater conditions and are often buried beneath the seabed to protect them from damage. Major companies and organizations invest in these cables to enhance connectivity, making them crucial for the modern digital world.
