The 40/42-850A-114 is a PXI/PXIe 4-channel multiplexer with FC/PC connectors and is part of Pickering's range of PXI Fiber Optic MEMS Switching modules. They are available in many high density formats with a choice of different connector styles to suit most applications: FC/APC (for optimal performance), FC/PC and SC/PC for general applications and LC and MU for high density applications. They are also available with an optional hardware interlock which, when activated, will return all optical switches to their default unpowered state.

Fiber optic multiplexers create a signal path by redirecting the optical signal into a selected output fiber. This is achieved using Micro-Mechanical Mirrors driven by a highly precise mechanism and activated via an electrical control signal.
