Exfo IQ-3400 Series PDL/Optical Loss Meters

  • Complete Loss Analysis Solution
  • Average and standard deviation reporting on multiple measurements
  • High resolution: 0.001 dB
  • Coupling Ratio


The Exfo IQ-3400 Series PDL/Optical Loss Meters was developed for the IQ-200 Optical Test System. They are designed for laboratory and manufacturing measurement applications using the IQ-203 Mainframe or an IQ-206 PC Expansion Card.

The IQ-3400 can perform complete component characterization with the following measurements: polarization dependent loss; insertion loss; optical return loss; excess loss; coupling ratio; polarization dependent coupling ratio; and reference power. Standard deviation, averaging and a graphical interface allow for complete component characterization.

The Exfo IQ-3400B PDL/OL Meter uses the scanning method for simple, flexible component characterization on the production floor. Start with a laser source, use the IQ-5100B to scramble the polarization state of the signal, and then take a power acquisition with the IQ-3400B. Getting reliable PDL measurements is easy with the streamlined IQ PDL test setup.

Back up your PDL measurements with the IQ-3400B's optical return loss (ORL) test function. PDL can be caused by ORL from a scratched connector. If the PDL reading on a connectorized device seems unusually high, the ORL tester lets you check for loss due to connector damage.
