Optical Switches
The LCFF Series fiber optic switch provides exceptional performance with ultra-broadband coverage from UV to IR, low optical loss, minimal temperature dependence, high on/off ratio, vibration insensitivity, and compact size. It connects optical channels through direct fiber-to-fiber coupling, where the light path is continuous with index-matching liquid filling the tiny gap between the coupling fibers, eliminating unwanted surface reflection issues. Channel switching is activated via an electrical relay, and the latching operation preserves the selected optical path after the electrical power is removed. The switch is bidirectional and conveniently controllable by a 4.5V signal. The LCFF Series switch accommodates large-core fibers ranging from 0.2 to 0.4mm in diameter, with transmission characteristics identical to fiber.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
High Stability, Large Core Ultra-Broadband/Low-Loss 1x1, 1x2, 1x3 Fiber Optical Switch: Optical signal routing depends on preserving the optical budget through the complete path. The 488, 630, 780, 850, 980, 1060, 1310, 1550, 2000, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (200 μm (NA0.22), 300 μm (NA0.22), 400 μm (NA0.22), 500 μm (NA0.22), 600 μm (NA0.22), Special) must match the connected components.

Technical FAQ
Fiber Core Size: 200 μm (NA0.22), 300 μm (NA0.22), 400 μm (NA0.22), 500 μm (NA0.22), 600 μm (NA0.22), Special · Fiber Cover: Bare fiber, 2 mm Jacket, 3mm jacket, 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.
Test Wavelength: 488, 630, 780, 850, 980, 1060, 1310, 1550, 2000, Special. 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.
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.
