The technology that enables high-speed broadband internet access through fiber-optic cables is called fiber-optic communication. Fiber-optic networks use thin strands of glass or plastic to transmit data as light signals, allowing for faster and more reliable internet connections compared to traditional copper cables. This technology supports higher bandwidth and significantly reduces signal degradation over long distances, making it ideal for delivering high-speed services such as video streaming, online gaming, and cloud computing applications. Fiber-optic technology is a key driver in enhancing global internet infrastructure.
