Precision MEMS Variable Attenuators

SKU: PMOA

The PMOA Series Precision Variable Optical Attenuator (VOA) delivers fast response and precision attenuation with calibrated performance curves, enabling rapid and repeatable adjustments with excellent long-term stability. The design ensures low insertion loss, high repeatability, and drift-free operation under varying environmental conditions. The PMOA supports a wide range of fiber types, including single-mode, multimode, and polarization-maintaining, and operates across a broad spectral band from 750 to 2400 nm. This turnkey unit includes USB and RS232 interfaces with GUI software supporting sequential programming for automated control. A PCB sub-mount version is also available, offering UART control and 0–5 V power input for seamless OEM system integration.
