optical communication technologies

Optical communication technologies transmit data as light signals through fiber optic cables or free-space optics. These systems use lasers or LEDs to encode information onto light beams, which travel long distances with minimal loss and high speed. Fiber optics are widely used for internet, telephone, and television because they provide fast, reliable, and secure data transfer. The light signals are converted back into electronic data at the receiving end. Overall, optical communication offers a highly efficient way to transmit large amounts of data quickly across vast distances, supporting modern connectivity and digital communication systems.
