Fiber optic cables are thin strands of glass or plastic that transmit data as light signals. They are designed to carry large amounts of information over long distances with minimal loss. This technology is widely used in telecommunications, internet connections, and cable television. The main advantage of fiber optic cables is their high speed and bandwidth compared to traditional copper cables. They are less susceptible to interference and can operate in various environmental conditions. As a result, fiber optics are becoming increasingly popular for modern communication networks.
