1 × 4 MEMS Switch

AFR's MEMS Optical Switch is based on an electrostatic drived micro-electro-mechanical-system (MEMS) chip. The MEMS chip consists of a tilting mirror to change light coupling between input and output fibers.The components are characterized with low insertion loss, high return loss, excellent environmental stability and reliability. The optical swtich has been widely used in fiber optics communication equipment, fiber instruments, and fiber sensing to switch channels.
