Fiber optic communication is a method of transmitting data as light pulses through thin strands of glass or plastic fibers. This technology allows for high-speed data transfer over long distances with minimal signal loss, making it ideal for internet and telecommunications networks. The core principle behind fiber optics is total internal reflection, which enables light to travel through the fiber without escaping. This results in faster and more reliable communication compared to traditional copper cables, leading to advancements in various fields such as television, internet, and telephony.
