  • Fiber optic communication optical transmission

    Fiber optic communication optical transmission

    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. By replacing the solid core with an air-filled channel, hollow-core fibers (HCFs) allow light to propagate at nearly its vacuum speed, reaching approximately 3×10 8 meters per second. 5 microseconds per kilometer, offering a 30 to 50 percent speed increase.
