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.

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-Broadband/Low-Loss 1×3, 1×4 MEMS Fiber Optical Switch: Optical signal routing depends on preserving the optical budget through the complete path. The 488, 532, 630, 780, 850, 980, 1060, 1310, 1550, 2000, 2.3-4.1 μm, 3.2-5.5 μm wavelength specification sets source and detector compatibility, while listed loss or isolation figure (<3dB / <1.3dB / <1.3dB / <1 dB / <1dB / <0.9dB / <0.4dB / ≤0.4dB) determines link margin and channel leakage. The fiber/interface entry (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) must match the connected components.

Automated fiber test

Ultra-Broadband/Low-Loss 1×3, 1×4 MEMS Fiber Optical Switch: Automated fiber test depends on preserving the optical budget through the complete path.

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.
