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. With the advent of optical fiber as a transmission medium and semiconductor laser as a light source. In this article, we will learn about Optical Fiber Light Transmission, Optical fiber light transmission is a technology that enables the transmission of data and information through thin strands of glass or plastic fibers using light signals. They're used extensively in telecommunications, datacomm, laser beam delivery, sensing, medical applications, and more. Fiber optics have had a huge impact on modern life.
