The IBP-202 Optical Bypass Switch is an industrial grade external bypass switch for optical-node failure in fiber optical networkinfrastructures. The IBP-202 Optical Bypass Switch prevents and saves communication from network failures during power loss. Whenpower failure occurs, the Bypass switch will swiftly set to bypass mode and isolate the main-network from the local networking device(See Figure 1). Bypass switches are commonly used in some major optical networks, such as in railway communication systems,factory automation, and power substation, where fiber link failures are not tolerated.
