Variable Optical Attenuators
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.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
MEMS Reflective 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, PM1310, PM980, PM850, MM 50/125, MM 62.5/125, Special) must match the connected components.

Technical FAQ
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.
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.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
