EXFO's FLS-5800 CD/PMD Analyzer Source is a modulated, polarized, high-power SLED. Thanks to its high power density, you can use it as a broadband source for DWDM channel and component testing. High Modulation The FLS-5800's high modulation makes it a perfect complement to the FTB-5800 Chromatic Dispersion Analyzer, whose technology is based on the phase-shift method. This first-class duo lets you run chromatic dispersion (CD) measurements through amplifiers such as EDFAs, providing the highest accuracy in field CD testing. High Degree of Polarization When measuring PMD and a broadband, polarized source is required, turn to the FLS-5800, which features a high degree of polarization. Test PMD through EDFAs by combining the FLS-5800 with patent-design breakthrough technology FTB-5500B PMD Analyzer.
