VOAPXIe – Modular Variable Optical Attenuator
This innovative module enables new mixed-signal testing capabilities for PXI users. Each VOAPXIe module has an integrated power meter for 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 the low insertion loss of VOAPXIe.
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.
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.
