Optical Switches
Ultra-Broadband/Low-Loss 1×3, 1×4 MEMS Fiber Optical Switch
The FF Series fiber optic switch connects optical channels using a micro-mechanical fiber-to-fiber auto-alignment platform activated via an electrical relay. Its advanced, lensless design enables ultra-low insertion loss, broad wavelength compatibility without coatings, and high optical power handling at a significantly reduced cost. The switch is bidirectional and supports all fiber types — including SM, MM, PM, double-cladding, bend-insensitive, and large/small core fibers. Latching operation maintains the optical path after control signal removal, with convenient 5V TTL control. A proprietary, non-fluorescent index-matching liquid fills a sub-5 µm gap between fibers. When configured with PM fibers, both polarizations are transmitted consistently with the fiber orientation and maintain high extinction ratio.

Integration and compatibility
Use these checks to connect Ultra-Broadband/Low-Loss 1×3, 1×4 MEMS Fiber Optical Switch 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: SMF-28, SMF-28e, Corning XB, SM450, SM1950, SM600, Hi780, SM800, Hi980, Hi1060, Draka BBE, SM400, PM1550, PM1950, PM1310, PM405, PM480, PM630, PM850, PM980, PM780, PM460, OM1, OM2, OM3, OM4, MM 105/125μm, FG50LGA, STP 50/125, IRZS23, IRZS32, UV180nm, LMA-PM-10 · Fiber Cover: Bare fiber, 900um tube, Special
- 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
- Test Wavelength: 488, 532, 630, 780, 850, 980, 1060, 1310, 1550, 2000, 2.3-4.1 μm, 3.2-5.5 μm · Wavelength Range*: 360 – 530nm / 480 – 650nm / 620 – 650nm / 760 – 980nm / 980 – 1550nm / 960 – 1080nm / 1020 – 1900nm / 1.7 – 2.3 µm
- 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.
- Control interface
- Driver: Non, USB, RS232, TTL
- Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
