Optical Switches

High Stability, Large Core Ultra-Broadband/Low-Loss 1x1, 1x2, 1x3 Fiber Optical Switch

The LCFF Series fiber optic switch provides exceptional performance with ultra-broadband coverage from UV to IR, low optical loss, minimal temperature dependence, high on/off ratio, vibration insensitivity, and compact size. It connects optical channels through direct fiber-to-fiber coupling, where the light path is continuous with index-matching liquid filling the tiny gap between the coupling fibers, eliminating unwanted surface reflection issues. Channel switching is activated via an electrical relay, and the latching operation preserves the selected optical path after the electrical power is removed. The switch is bidirectional and conveniently controllable by a 4.5V signal. The LCFF Series switch accommodates large-core fibers ranging from 0.2 to 0.4mm in diameter, with transmission characteristics identical to fiber.
