Variable Optical Attenuators
MEMS Reflective Fiber Optical Variable Attenuator – 1D
The MEMS Series Fiber Optical Variable Attenuator uses a patented thermal-activated micro-mirror, moving-in and -out optical paths, uniquely featuring a large extinction ratio, high stability over a wide temperature range, and a very long life cycle. The thermal MEMS is insensitive to moisture and ESD without drift issues, providing a high-reliability platform for over 25 years of continuous operation. The MEMS Straight Series VOAs are configured in single and dual channels (activated at the same time). The VOAs are bidirectional and are Telcordia standards GR1221 qualified. We provide customized design and modular assemblies to meet control and integration applications.

Integration and compatibility
Use these checks to connect MEMS Reflective Fiber Optical Variable Attenuator – 1D to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SMF-28, PM1550, PM1310, PM980, PM850, MM 50/125, MM 62.5/125, Special · Fiber Cover: Bare fiber, 900 µm 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 and loss budget
- Test 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.
