The application of computer network technology in electronic information engineering

Abstract

With the development of computer network technology, the coverage of the WAN is also getting bigger and bigger, while the electronic information engineering needs to provide long-distance communication channels and form a remote network. In the physical link of the WAN, the optical fiber, different from other media, can effectively resist external interference and realize information and data transmission through the optical pulse. However, in addition, the communication trunk line will also affect the transmission effect, which will need to distinguish between public lines and professional lines accordingly.
