The etMEMS™ Series Fiber Optical Switch connects optical channels by redirecting incoming optical signals into selected output fibers. This is achieved using a proprietary thermal activated micro-mirror, moving-in and -out optical paths, uniquely featuring ultra small size, rugged. The MEMS Latching type with built-in driver switches can be directly mounted on printed circuit board with configurations of 1×1, Dual 1×1, Quad 1×1, 1×2, Dual 1×2, Full 2×2, and Dual Full 2×2 Single mode and Multimode.

This advanced design offers unprecedented high stability and high reliability as well as low cost advantage.
