Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Manual Variable Fiber Optical Attenuator — Regular: Optical power control depends on preserving the optical budget through the complete path. The 1250-1640nm, 1310nm, 850nm, 850-1310nm wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28, PM 1550, PM 1310, 50 μm, 60 μm) must match the connected components.

Technical FAQ
Fiber Type: SM28, PM 1550, PM 1310, 50 μm, 60 μm · Fiber Cover: Bare fiber, 900um tube, 3mm 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.
Wavelengths: 1250-1640nm, 1310nm, 850nm, 850-1310nm. Check the Variable Optical Attenuators 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.
