VOAPXIe – Variable Optical Attenuator Module

This innovative module enables new mixed-signal testing capabilities for PXI users. With an integrated power meter, VOAPXIe provides precise output power control, even with fluctuating input.

Features

Fast attenuation speed

Fast attenuation speed minimizes the down time during changes in attenuation settings to shorten your overall test time.

Low insertion loss

Maximise your power budget with low insertion loss.

Built in power monitoring capability

Eliminate the need for an extra power meter with the built-in power monitoring capability. Know the actual power coming out of the attenuator all from the same VOA module.

 Constant power output mode

With the built-in closed-loop power monitoring, VOAPXIe can operate in the constant power output mode to stabilize fluctuating input power.

Wide coverage of operational wavelengths

One versatile tool to cover a wide variety of applications.

Seamless PXI integration

Take advantage of PXI’s integrated triggering and synchronization capabilities across electrical and optical instruments.

Product warranty

This product comes with a 3 year warranty.

Applications

With its wide coverage of operational wavelengths, VOAPXIe can be used for a wide variety of applications, including:

• Optical power budget analysis
• Instrument power calibration
• BER testing
• EDFA gain linearity test
• Transceiver stress testing
• Receiver sensitivity testing
• Loss simulation

Reliability

VOAPXIe is designed to be used in continuous production environments. It is built to the highest standards using components with high Mean-Time-Between-Failure (MTBF) specifications to minimize downtime.

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.
