Variable Optical Attenuators
SFP Variable Optical Attenuator 12
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.

System integration
Integration and compatibility
Use these checks to connect SFP Variable Optical Attenuator 12 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- 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 and loss budget
- 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.
Technical FAQ
Integration questions for SFP Variable Optical Attenuator 12
Which fiber and connector does the SFP Variable Optical Attenuator 12 use?
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.
How should the SFP Variable Optical Attenuator 12 be included in an optical power budget?
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.
