Optical Switches
Ultra-Broadband/Low-Loss Single or Dual 1×N Fiber Optic Switch System
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.

Integration and compatibility
Use these checks to connect Ultra-Broadband/Low-Loss Single or Dual 1×N Fiber Optic Switch System to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- 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 and loss budget
- 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.
