Variable Optical Attenuators
The mini MEMS Variable Optical Attenuator Integrated with Input Optical Power Monitor is a hybrid fiber optical device that integrates a thin-film tap of flat spectral response and a high sensitivity PIN photodiode for power monitoring applications with a MEMS VOA. The Power Monitor minimizes component assembly costs and module footprint. The thermal MEMS VOA has little temperature dependence and drift. It is intrinsically more reliable than electrostatic MEMS VOAs. The Power Monitor has low insertion loss and low dark current with high-temperature stability over a wide wavelength range from 1260nm to 1620nm band.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Vibration Insensitive MEMS VOA with Input Power Monitor 1D: Optical power control depends on preserving the optical budget through the complete path. The C+L, 1310, 1550, 1260-1620, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, PM1550, Special) must match the connected components.

Technical FAQ
Fiber Type: SMF-28, PM1550, Special · Fiber Cover: Bare fiber, 900um tube, Special. 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: C+L, 1310, 1550, 1260-1620, 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.
