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.

Integration and compatibility
Use these checks to connect Ultra Low-Loss/Broadband/Large Core/Latching 1×N Fiber Switch/VOA to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: 50/125, 62.5/125, 105/125, 100/140, 200/NA.22, 300/NA.22, 400/NA.22, 600/NA.22, 800/NA.22, 1000/NA.22, 2000/NA.22, SMF-28, PM1550, SM400, SM450, SM600, 780HP, Hi1060, SM1950, PM1950 · Fiber Cover: Bare fiber, 2 mm Jacket, 0.9mm tube
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength *: 1550, 1060, 1310, 2000, 650, 780, 850, 1310/1550, 350, 450, 520
- Check the Optical Switches passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
