The Keysight E5574A Optical Loss Analyzer characterizes insertion loss, return loss, gain, and polarization-dependent loss (PDL) in active and passive optical components. This instrument delivers PDL accuracy to ±0.005 dB with absolute power accuracy of ±2.2%, making it suitable for R&D, manufacturing, and field service in optical communications. A built-in fiber-based polarization controller covers all states of polarization, while modular optical head compatibility enables operation across extended wavelength ranges.
