The MEMS Series Ultra-Mini Fiber Optical Switch unifies different switch configurations of 1×1, Dual 1×1, Quad 1×1, 1×2, Full2x2, Dual 1×2, and Dual Full2x2 for both Single mode and Multimode onto the same package, providing the same PCB-direct-mountable footprint.

The switches are produced based on Photonwares Patents US 8,203,775. It 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. This advanced design offers unprecedented high stability and high reliability as well as low cost advantage.

Photonwares provides customized designs to meet specialized feature applications. Photonwares also offers modular assemblies that integrate other components to form a full function module or subsystem.
