Fiber optics is a technology that uses thin strands of glass or plastic, known as optical fibers, to transmit data as light signals. These fibers are capable of carrying large amounts of information over long distances with minimal loss of quality. This makes fiber optics an essential component in modern communication systems, including internet, television, and telephone networks. The core of each fiber optic strand is surrounded by a layer called the cladding, which reflects light back into the core, allowing it to travel through bends and curves. This unique property enables high-speed data transmission, making fiber optics faster and more efficient than traditional copper wires.
