VOAPXIe – Variable Optical Attenuator

The VOAPXIe is a reliable, fast and high density attenuation solution that seamlessly integrates with the PXI Platform.

This innovative module enables new mixed-signal testing capabilities for users of the PXI Platform. Each VOAPXIe module has an integrated power meter for precise output power control, even with fluctuating input.

Key features

  • Seamless integration with PXIe chassis
  • 1 or 2 attenuators per module
  • Choose between CWDM8 broadband or narrow wavelength range
  • Integrated power meters for precise output power control
  • Polarization-maintaining fiber compatible
  • Designed for continuous-production and research environments


VOAPXIe is designed to be used in continuous production environments, so that your testing can run reliably round the clock. It is built to the highest standards using components with high Mean-Time-Between-Failure (MTBF) specifications to minimize any potential downtime in your production.

Stable power output

The built-in power meter and power stabilization function lets you set and maintain the output power stability even when the input power fluctuates. You will get reliable and repeatable test results each and every time.

Select the best fit for your application

You can choose the broad wavelength range model for versatility or the narrow wavelength models for the best accuracy and performance.
