Variable Optical Attenuators

Linear Digitally Control MEMS Variable Attenuators

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.
