The EXFO IQ-9401 Wavelength Reference Module is an essential tool for validating the wavelength accuracy of optical spectrum analyzers and other wavelength-sensitive test instruments. It generates known reference lines across a specified range, typically using gas or solid-state reference sources.
This module allows users to calibrate and verify measurement accuracy, ensuring that test results remain within strict tolerances required for DWDM and broadband testing. Integrated into the IQS platform, the IQ-9401 automates the calibration workflow and enhances test system consistency.
It is commonly used in development labs, metrology applications, and production lines where test traceability is crucial. The unit features long-term stability and compact integration, making it a standard accessory for wavelength-critical testing.
