Precision MEMS Variable Attenuators

SKU: PMOA

The High Precision Series Variable Optical Attenuator (VOA) is built on a MEMS-based platform with an integrated high-precision optical position sensor, offering low insertion loss, ultra-high setting and repeatability precision of 0.1 dB, and a linear response to input control voltage. Once the attenuation level is set, it remains stable regardless of environmental variations, ensuring high reliability. The VOA is available in single-mode (SM), multimode (MM), and polarization-maintaining (PM) fiber configurations. A fast-response version is also available, utilizing calibration curves for rapid adjustments. The VOA integrates with a PCB featuring USB connectivity and GUI software, enabling sequential programming capabilities. The PCB includes sub-mount pins—two for 0-5V DC power input and two for 0-5V control input, allowing direct mounting onto other PCBs for seamless system integration.
