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 at very high speeds. This technology is commonly used in internet connections, telephone systems, and cable television, making it essential for modern communication. The core of a fiber optic cable is surrounded by a layer called the cladding, which helps keep the light signals contained. Because of their ability to transmit data without interference, fiber optic cables are often preferred over traditional copper wires, especially in areas where high-speed internet is crucial.
