Variable Optical Attenuators
Our etMEMS™ Series SFP VOA is based on a proprietary micro-electro-mechanical mechanism featuring compact design, simple construction, easy direct drive, and excellent optical performance. The SFP VOA integrates a single channel VOA and tap power monitor into MSA compliant compact SFP form factor and provides I2C communication interface for easy system integration. The device has built-in firmware that linearizing the attenuation to the control signal. The power tap provides a digital warning when the output optical signal level below certain level. Either normally-open or normally-closed configurations are available.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
SFP Variable Optical Attenuator 12: Optical power control depends on preserving the optical budget through the complete path. The 1310, 1550, C+L, 1260~1620 wavelength specification sets source and detector compatibility. The fiber/interface entry (LC/PC, Special) must match the connected components.
SFP Variable Optical Attenuator 12: Receiver calibration depends on preserving the optical budget through the complete path. The 1310, 1550, C+L, 1260~1620 wavelength specification sets source and detector compatibility. The fiber/interface entry (LC/PC, Special) must match the connected components.

Technical FAQ
Connector: LC/PC, 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: 1310, 1550, C+L, 1260~1620. 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.
