Exfo IQ-3400B PDL/OL Meter

The Exfo IQ-3400B PDL/OL Meter is a modular instrument for precise measurement of Polarization Dependent Loss (PDL), Optical Loss (OL), and Optical Return Loss (ORL) in fiber optic components and systems. Engineered for laboratory and manufacturing environments, it employs a scanning measurement method that utilizes an external laser source and polarization scrambler to deliver rapid, reliable characterization data. The module integrates into the Exfo IQ-200 Optical Test System platform, supporting detailed component assessment and signal quality evaluation across production and development workflows.
