The optical fiber network is the backbone network of Heilongjiang electric telecommunication network, so its safe and stable operation is very important.

Using the monitoring project proposed here, it is demonstrated experimentally that it can realize real-time and on-line monitor to optical fiber network.

A real-time Ultrahigh-speed optical fiber network design concept was proposed for fly-by-light aircraft in this paper. The advantages of the star and ring topology structure were integrated.
