Summary : Fiber optic cables use light pulses to transmit data through ultra-thin glass or plastic strands, offering high-speed, long-distance communication. Where traditional copper cables max out at about 10 gigabits per second, fiber optic cables can handle 100 gigabits per second with commercially available hardware, and. 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. In an era where speed and bandwidth are critical, understanding the principles behind fiber optic cables becomes essential. This method allows high-speed data transmission over long distances with minimal loss, making it essential for modern data networks, telecommunications, and the internet.
