Fiber optics is a technology that uses thin strands of glass or plastic to transmit data at high speeds over long distances. Light pulses are sent down the fibers, which have the ability to carry large amounts of information with minimal signal degradation. Fiber optic cables are commonly used in telecommunications networks, internet connections, and other data transmission systems due to their high data capacity and low interference vulnerability. This technology has revolutionized communication systems and has enabled faster, more reliable data transmission compared to traditional copper cables.
