The application fields are as follows:
The application field of optical fiber communication is very wide, mainly used for local trunk lines. The advantages of optical fiber communication can be fully played here, gradually replacing cables, and widely used.
It is also used for long-distance trunk line communication. In the past, cable, microwave and satellite communication were mainly used. Now, optical fiber communication is gradually used and a bit transmission method with global advantages has been formed; It is used for global communication network and public telecommunication network of various countries (such as national primary trunk line, provincial secondary trunk line and branch line below county level in China); It is also used for high-quality color TV transmission, industrial production site monitoring and dispatching, traffic monitoring, control and command, urban cable TV network, and common antenna (CATV) system, as well as optical fiber LAN and other applications such as in aircraft, spacecraft, ship, mine, power sector, military, corrosive and radioactive.
