The internet connects countries and continents primarily through submarine fiber optic cables that run under oceans. These high-capacity cables transmit data using light signals, enabling global communication. The process involves local ISPs routing traffic through cable landing stations, undersea. Fiber-optic communication is a form of optical communication for transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred. The global Internet is connected through a complex web of undersea cables, land-based infrastructure, and satellite links, allowing data to travel vast distances at incredible speeds and fundamentally shaping how the world communicates and operates. In this article, we will discuss the main differences between them.
