optical transmission systems

Optical transmission systems use thin strands of glass or plastic fibers to carry data as light signals over long distances. These systems encode information into light pulses, which travel through the fibers with minimal loss, allowing for high-speed, high-capacity communication. They form the backbone of internet, phone networks, and cable TV, enabling rapid data exchange across cities, countries, and continents. The technology relies on precise light sources, such as lasers, and sensitive detectors to convert light back into electronic signals, ensuring reliable and efficient transmission of vast amounts of information.
