Ultra-Broadband/Low-Loss 1×3, 1×4 MEMS Fiber Optical Switch

The FF Series fiber optic switch connects optical channels using a micro-mechanical fiber-to-fiber auto-alignment platform activated via an electrical relay. Its advanced, lensless design enables ultra-low insertion loss, broad wavelength compatibility without coatings, and high optical power handling at a significantly reduced cost. The switch is bidirectional and supports all fiber types — including SM, MM, PM, double-cladding, bend-insensitive, and large/small core fibers. Latching operation maintains the optical path after control signal removal, with convenient 5V TTL control. A proprietary, non-fluorescent index-matching liquid fills a sub-5 µm gap between fibers. When configured with PM fibers, both polarizations are transmitted consistently with the fiber orientation and maintain high extinction ratio.
