Optical Communications and Networking

When data is transmitted across optical fibres utilising optical signals, or light, it is referred to as optical networking or communications. This technology is essential to contemporary telecommunications because it provides dependable, secure, and fast data delivery. Optical fibres enable large bandwidth and long-distance communication by transmitting data as light pulses. Optical networks facilitate phone, video, and internet services by effectively directing data through switches and routers. New technologies such as fiber-to-the-home (FTTH) give homes access to fast internet. The globe is connected thanks in large part to optical communication, which enables local networks as well as international internet traffic, completely changing the way people exchange information and communicates.
