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

SKU: LCFF

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 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. The platform is robust, insensitive to temperature and vibration, and available in compact configurations of 1×1, 1×2, 1×3, and 1×4. For 1xN applications, a larger format is available.
This switch uses a specially formulated index-matching liquid that does not generate fluorescent. The liquid fills a gap of less than 5 µm.
The switch’s transmission spectrum preserves that of the fiber itself, without introducing additional distortion, making it ideal for spectroscopic applications. This design ensures high fidelity in signal transmission, maintaining the integrity of the original fiber characteristics for precise analytical measurements.
Switches with PM fibers transmit both polarizations the same way as the fiber.
