Optical Switches
The LBSM Series optical fiber switch delivers exceptionally low insertion loss — typically around 0.3 dB — regardless of array size, and supports up to 300 fiber ports in a compact, bidirectional architecture. Compatible with any fiber type and covering a broad wavelength band from 300 nm to 2300 nm, the LBSM switch is ideal for testing environments requiring consistent optical performance. It is available in single- and dual-channel configurations, with dual channels operating simultaneously. For PM fiber versions, the switch maintains both polarization axes identically to the input fiber. Uniform optical paths are ensured across all output ports. The device is controlled via RS232 or USB and comes with intuitive graphical software.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Ultra-Broadband/Low-Loss Single or Dual 1×N Fiber Optic Switch System: Optical signal routing depends on preserving the optical budget through the complete path. The 488 nm, 360 nm, 430 nm, 532 nm, 630 nm, 780 nm, 850 nm, 980 nm, 1060 nm, 1310 nm, 1550 nm, 2000 nm wavelength specification sets source and detector compatibility. The fiber/interface entry (50/125, SMF-28) must match the connected components.

Technical FAQ
Interface: USB, RS232, Ethernet, GPIB · Fiber Type: 50/125, SMF-28. 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: 488 nm, 360 nm, 430 nm, 532 nm, 630 nm, 780 nm, 850 nm, 980 nm, 1060 nm, 1310 nm, 1550 nm, 2000 nm. 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.
