On the optical transmission path network. The signal transporting by transmission equipment between the internet and Routing. When transmission equipment have problems or cut power, then signal can't transport between internet and routing. Then we will integrate the 2x2B optical switch to transmission equipment, to realize the function and ensure the system and other chain are on a normal communicating condition.
