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. Optical transmission is a method of sending information or energy from one point to another using light waves as the carrier medium. They convert electrical signals into light to transmit data quickly through fiber optic cables. You encounter them daily, such as when streaming videos or making calls.
