UV-IR No-Gap 1xN/2xN Fiber Optical Switch 0.3dB Loss

SKU: FFUL

The FFUL series of Ultra-Low Loss Fiber-Fiber 1×N Broadband Optical Switch uses a patent-pending v-groove alignment mechanism activated by a precision motor and immersed in a specially formulated, non-fluorescent index-matching liquid. This design eliminates optical coatings and air gaps, enabling a continuous light path with minimal loss and reflection across a broad spectral range from 200 to 2500 nm. MWIR and LWIR versions are available for use with specialty fibers. The switch supports single-mode and multimode fibers with core sizes from 50 to 1000 µm and is fully bidirectional, accommodating up to 300 ports. It retains its last position upon power loss and offers reliable long-term operation, validated through years of continuous use. Control is available via RS232 or USB with graphical software, and a LabVIEW interface is also supported. The switch is available as a fully packaged module. For PM fibers, both polarization states are transmitted identically to how they propagate in the fiber.
