Optical communication is a method of transmitting information using light waves. This technology primarily utilizes fiber optic cables, which are thin strands of glass or plastic that carry light signals over long distances. The light signals represent data, such as voice, video, or internet information, allowing for high-speed communication with minimal loss of quality. In addition to fiber optics, optical communication can also involve free-space transmission, where light signals travel through the air. This method is often used in applications like satellite communication and laser communication. Overall, optical communication is essential for modern telecommunications, providing faster and more efficient data transfer.
