Corephy Dual 2x2B Opto-Mechanical Bi-directional Fiber Optic Switch combine 2unit 2x2B Optical switch. Each 2x2 Bypass Optical Switch connects optical channels by redirecting 2 incoming optical signals into 2 output fibers. This is achieved using a opto-mechanical configuration and activated via an electrical control signal.
D2x2B Optical Switch is mainly used to realize optical path protection.
