光通信 用英文怎么说

Optical communication, also known as fiber-optic communication, is a technology that utilizes light waves to transmit data over long distances through specialized optical fibers. These fibers are incredibly thin glass or plastic cores that guide light signals with extremely low loss and minimal interference. Light signals, modulated to represent digital information, travel through the fibers using various techniques such as pulse-amplitude modulation (PAM), wavelength-division multiplexing (WDM), or coherent detection. Optical communication is widely used in telecommunications, internet infrastructure, and high-speed data transmission due to its capacity, speed, and secure nature.
