Fiber optic technology uses thin strands of glass or plastic to transmit data as light signals. This method allows for high-speed communication over long distances with minimal loss of signal quality. Fiber optics are commonly used in internet connections, telephone systems, and cable television. The core of a fiber optic cable is surrounded by a reflective layer, which helps keep the light signals contained within the core. This design enables faster data transfer compared to traditional copper wires, making fiber optics an essential component of modern telecommunications and networking infrastructure.
