Fiber Optic Technology

Fiber optic technology uses thin strands of glass or plastic—called optical fibers—to transmit data as pulses of light. These fibers are capable of carrying large amounts of information over long distances at very high speeds with minimal loss. Light signals are transmitted through total internal reflection inside the fiber, making the system immune to electromagnetic interference. Fiber optics are commonly used in internet connections, telecommunications, and cable TV, offering reliable, fast, and secure data transmission compared to traditional copper wires. Overall, fiber optic technology is a key enabler of modern high-speed communication networks.
