Optical Switches
The LFSH Series Fiber Optical Large Core Switch uniquely features high power handling up to 10W for large core fiber up to 1mm in diameter. It directly couples a pair of fibers and is activated via an electrical relay. The advanced design offers unmatched performances of ultra-broadband covering from 300 to 2400nm limited only by fiber intrinsic transmission, low optical loss, little wavelength dependence without coatings, high power handling, as well as low cost. The switch is bidirectional and conveniently controllable by 5V TTL. The latching operation preserves the selected optical path after the drive pulse has been removed, reducing power consumption. The switch has integrated electrical position sensors for verification. The switch is designed to be mounted onto a heat sink to dissipate the unwanted light.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Large Core UV-IR High Power Fiber Optical Switch: Optical signal routing depends on preserving the optical budget through the complete path. The Any, 488, 630, 780, 850, 980, 1060, 1310, 1550, 2000 wavelength specification sets source and detector compatibility. The fiber/interface entry (100 μm (NA0.22), 200 μm (NA0.22), 300 μm (NA0.22), 400 μm (NA0.22), 500 μm (NA0.22), 600 μm (NA0.22)) must match the connected components.

Technical FAQ
Fiber Core Size: 100 μm (NA0.22), 200 μm (NA0.22), 300 μm (NA0.22), 400 μm (NA0.22), 500 μm (NA0.22), 600 μm (NA0.22) · Fiber Cover: Bare fiber, 2 mm Jacket, 900um tube, 3mm Jacket. 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: Any, 488, 630, 780, 850, 980, 1060, 1310, 1550, 2000. 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.
