The transmission carrier of fiber optic communication is

The transmission carrier of fiber optic communication is light, typically a continuous wave generated by a laser or LED, which is modulated to carry information.In fiber optic communication, light serves as the carrier wave that transports data through optical fibers from a transmitter to a receiver . This light is usually in the infrared spectrum, invisible to the human eye, and is generated by high-precision semiconductor lasers or light-emitting diodes (LEDs) depending on the application . The continuous light wave provides a stable, high-frequency signal that can be modulated to encode digital information, such as binary ones and zeros . Modulation techniques alter properties of the light—such as intensity, phase, or frequency—to represent data. The simplest method, on-off keying, turns the light on and off rapidly to indicate binary values, while more advanced techniques like phase shift keying (PSK) or amplitude shift keying (ASK) allow higher data rates . Fiber optics is preferred over electrical transmission because light travels at extremely high speeds, offers enormous bandwidth, and is immune to electromagnetic interference, making it ideal for long-distance, high-speed communication . The optical carrier's stability and high frequency enable the transmission of voice, video, internet data, and other digital signals over local networks or across continents . In summary, the optical carrier—light—is the fundamental medium in fiber optic communication, and its modulation allows the efficient and reliable transmission of vast amounts of information over long distances.
