● MEMS based design The Micro ElectroMechanical System (MEMS) based multimode switch uses a movable mirror process to allow light to pass through the switch on activation or to be blocked/diverted when the switch is deactivated. This makes the switch particularly well suited for fail-safe bypass applications. Switches are available in on/off, 1x2, and 2x2 configurations. There is also a high attenuation version of the 2x2 switch used for node bypass (i.e. FDDI) applications. A standard PCB footprint allows the switch to be conveniently mounted with control electronics.
