Does optical communication use electrical cables or optical fibers
The answer lies in optical fiber communication, a revolutionary approach that uses fiber optic cables to transmit information as light signals. 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. 2dB/km) and wide bandwidth (several hundred MHz to THz) to enable long-distance, high-capacity communication. The information signal is always non electric signal (Audio or Video) therefore it is first.
