Signal Transmission

Signal transmission in fiber optics involves sending data as light pulses through thin strands of glass or plastic, known as optical fibers. When information—like internet data or telephone calls—is converted into light signals, these signals travel at high speeds over long distances without significant loss. The fiber’s structure reflects light internally, ensuring it follows the pathway without escaping. This technology allows for faster, more reliable communication compared to traditional copper wires, making it essential for modern telecommunications and internet infrastructure.
