EXFO IQ-203 Optical Test System W/ IQ-2100,IQ5100,IQ3400B

The EXFO IQ-203 Optical Test System is a modular platform for laboratory and manufacturing fiber-optic characterization. This configuration combines the IQ-203 mainframe with three core modules: the IQ-2100 light source for stable wavelength-selectable output, the IQ-5100 polarization controller for signal state manipulation, and the IQ-3400B PDL/OL meter for precision loss and polarization measurements. The system houses up to three modules in the mainframe with expandability to 27 total modules via IQ-206 expansion units.

Windows-compatible software provides manual and automated measurement control, data analysis, and reporting capabilities.
