   Precisely measure the central wavelength and power of single or multiplexed laser signals with the Exfo IQS-5320 Multi-Wavelength Meter. This accurate instrument is, in fact, a spectrum analyzer, but it is more commonly recognized in the industry as a wavelength meter. Its wavelength measurement precision is at least ten times better than what is available with traditional dispersion-based optical spectrum analyzers (OSAs).

   The measuring mechanism is based on a scanning Michelson interferometer. Specialized algorithms convert information from an interferogram (power as a function of path difference between two Michelson arms) into a spectral format (power as a function of wavelength), leading to highly accurate wavelengths.


  • Minimum Wavelength: 1450 nm
  • Maximum Wavelength: 1650 nm
  • Minimum Power: 1 uW
  • Maximum Power: 0.01 Watts
  • Power Resolution: 0.01 dB
  • Measurement Accuracy: 0.105925372517729 %
  • Simultaneous Power measurements
  • Internal Reference Type: HeNe
  • Wavelength Accuracy: +/-0.005nm
  • Drift Curve Generation: 1 pm of resolution

   Calculate the central wavelength of up to 200 multiplexed signal channels simultaneously, while achieving 3 pm absolute accuracy with the information extracted from the raw data provided by the interferogram. A reference sourcea continuous wave (CW) HeNe laseris integrated into the Michelson interferometer to ensure that every scan counts and that the unit will have excellent long-term precision. Annual verification against a more accurate instrument or reference source provides the requisite traceability for using the IQS-5320 as a calibration unit for Fabry-Perot (FP) lasers, distributed-feedback (DFB) lasers and tunable distributed-Bragg-reflector (DBR) lasers, as well as more general transmitter or transceiver units.
