Now the high-speed optical transmission system is limited by the transmission distance

New optical fiber

such as ultra-low loss fiber and large effective area fiber

can be used to facilitate the large-scale deployment of high speed optical transmission system. First introduce the characteristics of the new type of optical fiber

then analyzes the development direction of transmission network. Finally the regional network model serve as an example to analyze all kinds of new type fiber performance and value in the high-speed optical transmission system.
