Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
MEMS Fiber Optical Variable Attenuator – 1D: Optical power control depends on preserving the optical budget through the complete path. The 1260~1620, 1060, 1310, 1550, 850, 850/1310, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, PM1550/250, PM1310/250, PM980/250, PM850/250, MM 50/125, MM 62.5/125, Special) must match the connected components.

Technical FAQ
Fiber Type: SMF-28, PM1550/250, PM1310/250, PM980/250, PM850/250, MM 50/125, MM 62.5/125, Special · Fiber Cover: Bare Fiber, 900 µm Loose 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, 1310, 1550, 850, 850/1310, Special. 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.
