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. The light pulses represent data, allowing for high-speed communication with minimal loss of signal quality. This form of communication is widely used in various applications, including internet connections, telecommunications, and cable television. Optical communications offer advantages such as higher bandwidth, faster data transfer rates, and resistance to electromagnetic interference, making them essential for modern communication networks.
