The ILX Lightwave FPM-8220 is a fiber optic power meter engineered for precision optical power measurements across R&D and manufacturing environments. It delivers high accuracy and repeatability with exceptionally low polarization dependence, making it suitable for telecommunications and component testing applications. The instrument accepts interchangeable measurement heads, enabling flexible measurement ranges and wavelength coverage. A large 7-segment LED display with integrated dot matrix provides real-time power readouts in dBm, Watts, or bar graph format. Integrated data logging stores instrument configurations directly from the front panel, while USB 2.0 and IEEE 488.2 GPIB interfaces enable automated test sequences and remote operation. LabVIEW drivers are available for integration into custom measurement systems. The FPM-8220 maintains backward compatibility with remote commands from the legacy FPM-8210 model.
