Optical Switches

Ultra Low-Loss/Broadband/Large Core/Latching 1×N Fiber Switch/VOA

The FFLC Series 1xN Optical Switch enables reliable optical channel selection by directly aligning fiber cores using a high-precision miniature motor — without lenses or AR coatings — achieving typical insertion loss around 0.3 dB. Optional index-matching liquid can be used to fill the fiber gap and an option, reducing loss by 0.2 dB and eliminating reflections, which is desirable for interferometry applications. The switch features a latching mechanism that maintains the selected path without electrical power and can function as a high-resolution attenuator for large-core fibers. Our innovative design supports an ultra-broad spectral range from 200 nm to 3000 nm, limited only by fiber transmission.
