Fiber optics is a technology that uses thin strands of glass or plastic fibers to transmit data as pulses of light rather than electrical signals, allowing for high-speed and long-distance communication. This method provides a significant advantage over traditional metal wiring, such as copper cables, because it enables much faster data transmission rates and is not susceptible to electromagnetic interference. Fiber optic cables are central to modern telecommunications infrastructure, supporting internet, telephone, and television services with greater bandwidth and reliability. The technology is also used in medical instruments, automotive and aviation engineering, and networking within and between data centers. Fiber optics continue to evolve, playing a crucial role in expanding the capabilities of global communication networks and supporting the proliferation of digital technologies.
