Optical transmission is a research area that focuses on the transmission of information using light signals. This field encompasses the study of optical fibers, lasers, and other components that are used to transmit data over long distances at high speeds. Researchers in this area work to improve the efficiency, reliability, and speed of optical communication systems, as well as develop new technologies for applications such as telecommunications, data networking, and sensing. Optical transmission plays a crucial role in modern communication systems, enabling the high-speed transfer of vast amounts of data over long distances with minimal signal degradation.
