Optical communications is a technology that uses light to transmit information over distances. This method typically employs fiber optic cables, which are thin strands of glass or plastic that carry light signals. These signals can represent data such as voice, video, and internet traffic, allowing for high-speed communication. The main advantage of optical communications is its ability to transmit large amounts of data quickly and over long distances with minimal loss. This technology is widely used in telecommunications networks, data centers, and internet infrastructure, making it essential for modern communication systems.
