Compared to conventional metallic cables, optical fiber provides an advantage of low loss (~ 0. 2dB/km) and wide bandwidth (several hundred MHz to THz) to enable long-distance, high-capacity communication. 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. It was almost a century later before optical-based communication was put to practical use, thanks in large part to the invention of optical fiber and lasers.
