Enhanced Performance with MEMS VOA with PM Mode
MEMS VOA PM (Polarization Maintaining) is designed to preserve polarization in fiber optic systems. Polarization is an essential aspect of light signals in optical fibers, crucial for industries such as sensing, measurement, and communications. Our MEMS VOA PM attenuates light signals while maintaining polarization within the fiber optic system. Compact in size, high in precision, and operating at high speeds, it allows real-time adjustment of signal power. With exceptional stability, it maintains polarization even in dynamic environments.

MEMS VOA is based on micro-electro-mechanical systems (MEMS) technology. It utilizes rotating MEMS mirrors to control the optical coupling between input and output fibers, achieving precise attenuation levels. Our MEMS VOA offers two variants with different default states: bright type and dark type. The bright type exhibits the lowest loss state at 0 V, while the dark type achieves the lowest insertion loss between 4.5-5V voltage range. With a compact package, our VOA ensures high reliability, durability, and long lifespan.
