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.

Application Notes
Relative Intensity Noise (RIN) Measurement
Semiconductor laser Relative Intensity Noise (RIN) is an important parameter that can cause significant degradation to the performance of fibre optic communications links. It is important for both laser manufacturers and systems designers to understand how RIN is measured to ensure reliable, accurate and repeatable results.
Relative Intensity Noise (RIN) Application Note
Hardware Triggering of Coherent Solutions’ PXI Optical Modules
PXI’s integrated timing and hardware triggering capabilities offer a number of advantages over more
traditional software-initiated measurements. Learn how to make the best use of the hardware triggering capability present in Coherent Solutions’ PXIe photonics modules.
Hardware Triggering Application Note
Transient Testing in PXI
Until recently, measurements of power versus time were only available using expensive oscilloscopes and optical-to-electrical converters. These solutions required complex synchronisation and suffered from poor power accuracy and dynamic range in addition to requiring extra equipment.
With the TRACE capability of the optical power meters from Coherent Solutions, you can now capture accurate time domain power meter readings over the entire range of the power meter (>70dB).
