Fiber optics is a technology that sends data as pulses of light through strands of glass. This method allows high-speed data transmission over long distances with minimal loss, making it essential for modern data networks, telecommunications, and the internet. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred. In 1880, Alexander Graham Bell conducted an experiment where he made a phone call using natural light (sunlight) to convert his voice into light via a “photophone. It's the backbone of the internet, telephone networks, and more, offering unmatched bandwidth and distance. Unlike traditional copper or.
