Module4 (1×2 to 1×16)
MEMS 1xN PM optical switch module (1×2 to 1×16) is a non-latching optical switch based on Micro-Electro-Mechanical System (MEMS) technology. The optical switch module allows channel selection between a single input fiber and N output fibers. By rotating the MEMS mirror of the PM optical switch, the path of the optical signal can be controlled and switched to accommodate connection requests while simultaneously maintaining the polarization state of the signal.
This PM optical switch is also a bi-directional switch that can function as Nx1 selector. The MEMS 1xN PM optical switch module is characterized by compact size, long-life operation with exceptional reliability and durability.
