The EXFO IQS-5320-EI is a precision multi-wavelength meter that simultaneously measures wavelength and power across up to 200 multiplexed optical channels. Built around a scanning Michelson interferometer architecture, it delivers wavelength measurement precision at least ten times superior to traditional dispersion-based optical spectrum analyzers. An integrated CW HeNe laser reference ensures long-term accuracy and scan stability, making the instrument suitable for calibration of Fabry-Perot, distributed-feedback, and tunable distributed-Bragg-reflector lasers across manufacturing, R&D, and characterization workflows.
