The Physics Behind Fiber Optic Communication: How Light Transmits Data

In the modern world, high-speed internet, telecommunications, and data transmission are integral to everyday life. One of the most revolutionary technologies enabling this connectivity is fiber optic communication . Unlike traditional copper wires that use electrical signals, fiber optics rely on light to transmit vast amounts of data over long distances with minimal loss. This technology has become the backbone of global internet infrastructure, supporting everything from broadband connections to deep-sea cables spanning continents. This article delves into the physics behind fiber optic communication, explaining how light efficiently carries data through optical fibers, the different types of fiber optic cables, their advantages, and some frequently asked questions about the technology. Understanding Fiber Optic Cables A fiber optic cable is a bundle of thin, flexible fibers made of glass or plastic that transmit data in the form of light pulses. These cables consist of three main comp…
