Product Overview

NeoPhotonics MEMS VOA is an ultra-compact variable optical attenuator that easily drops into any optical network application. Both bright and dark configurations are available, with very low insertion loss and polarization-dependent loss, high dynamic range and high off-state extinction. The hermetically-sealed MEMS chip is insensitive to shock and vibration and is ESD safe up to 500V.

NeoPhotonics MEMS VOA is ideal for receiver protection or transponder power control, and it is also widely used in EDFAs of for equalization in multi-channel systems.
