Optical Switches
The LB Series Dual 1×2 fiber optic switch connects optical channels by redirecting an incoming optical signal into a selected output fiber. This is achieved using our patent pending opto-mechanical configuration and activated via an electrical control signal. Latching operation preserves the selected optical path after the driver signal has been removed. The switch has integrated electrical position sensors. Our new material-based advanced design significantly reduces moving part position sensitivity, offering unprecedented high stability as well as an unmatched low cost. Electronic driver is available for this series of switches. The switch is bidirectional. We offer a tight-bend-fiber version, which reduces the minimum bending radius from normal 15 mm to 7 mm. This feature enables a smaller overall foot print.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
LightBend™ Dual 1x2 SM Optical Switch: Optical signal routing depends on preserving the optical budget through the complete path. The 1060, C+L, 1310, 1410, 1550, 650, 780, 850, 1310 & 1550, 1260~1620, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, Corning XB, Draka BBE, Special) must match the connected components.

Technical FAQ
Fiber Type: SMF-28, Corning XB, Draka BBE, Special · Fiber Cover: Bare fiber, 900um loose 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: 1060, C+L, 1310, 1410, 1550, 650, 780, 850, 1310 & 1550, 1260~1620, 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.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
