Photonwares MEMS fiber optical switches are in volume production with many customers around the globe. It uniquely uses a state-of-the-art planar configuration in which each mirror moves within only two positions: in or out of the light path, as shown in the enclosed. Our unique digital micro-mirror technology advantageously eliminates the need for software position calibrations associated with conventional rotating MEMS mirrors that have long-term drift issues. The switches are based on a reliable thermal actuation that establishes optical signal paths in milliseconds, eliminating the risk of electrostatic stiction and high field electric discharge shorting. The switches feature intrinsic temperature insensitivity, latching to the positions against vibrations, direct driving, and low cost. The versatile platform accommodates various fibers of SM, PM, and MM. The passive switches support all date rates, ideally suited to manage optical networks intelligently and remotely with extremely low latency.
