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.

Application context

Why this design is used

Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.

Optical signal routing

Ultra Low-Loss/Broadband/Large Core/Latching 1×N Fiber Switch/VOA: Optical signal routing depends on preserving the optical budget through the complete path. The 1550, 1060, 1310, 2000, 650, 780, 850, 1310/1550, 350, 450, 520 wavelength specification sets source and detector compatibility. The fiber/interface entry (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) must match the connected components.

Automated fiber test

Ultra Low-Loss/Broadband/Large Core/Latching 1×N Fiber Switch/VOA: Automated fiber test depends on preserving the optical budget through the complete path.
