Optical Switches
The LB Series Ultra-mini fiber optic switch connects optical channels by redirecting incoming optical signals into selected output fibers, in 1×1, 1×2, and 2×2 Bypass configurations. This is achieved using a patented opto-mechanical configuration and activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed. The switch has integrated status contacts to provide an electrical readout of switch position. The new material-based advanced design significantly reduces moving part position sensitivity, offering unprecedented high stability as well as an unmatched low cost. It is designed for use in reconfigurable OADM, optical cross-connect system, and network switching for fault protection applications. An electronic driver is available for this series of switches. The switch is bidirectional.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
LightBend™ Ultra Mini 1x1, 1x2, 2x2 Bypass SM Optical Switch: Optical signal routing depends on preserving the optical budget through the complete path. The 1260-1620, 1060, C+L, 1310, 1410, 1550, 650, 780, 850, 1310 & 1550 wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28, Corning XB, Draka BBE) must match the connected components.

Technical FAQ
Fiber Type: SM28, Corning XB, Draka BBE · Fiber Cover: Bare fiber, 900um tube. 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: 1260-1620, 1060, C+L, 1310, 1410, 1550, 650, 780, 850, 1310 & 1550. 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.
