MEMS 4×4 Latching SM Optical Switch

The etMEMSTM Series 4×4 Fiberoptic switch connects 4 optical channels by redirecting incoming optical signals into 4 selected output fibers. This is achieved using a patent pending etMEMSTM configuration and activated via an electrical control signal. It uniquely features rugged thermal activated micro-mirror and latches to preserve the selected optical path after the drive signal has been removed. This novel design significantly reduces packaging requirement, offering unprecedented high stability as well as an unmatched low cost.

We offer tight-bend-fiber version, which reduces the bending radius. This feature enables smaller overall foot print.
