The VOA Series is a MEMS-based variable optical attenuator with fast attenuation speed, low insertion loss and in-built power meter. Its advanced power stabilization function lets you set and maintain the output power stability even when the input power fluctuates.
It is available in singlemode, multimode and polarization maintaining fiber types and various wavelengths to suit a wide range of applications.
With 1 or 2 channels in a single PXIe slot, it provides high channel density solution for easy integration in the versatile PXI platform.
