What type of network cable is optical fiber cable

Fiber optic cables are a type of networking cable that uses light to transmit data. Unlike traditional copper cables that use electrical signals, fiber optics rely on pulses of light to carry information, making them faster and more efficient over long distances. They are of the two main categories: single-mode for high-speed transfer over long distances and multi-mode for shorter lengths within buildings or campuses. The fiber which is used for optical communication is waveguides made of.
