The Need for Testing Low PMD Values in DWDM Components

This paper describes the benefits of using EXFO FPMD-5600 Femtosecond PMD Analyzer. The device enables optical component manufacturers to perform both first and second order PMD measurements. Using an input amplified-spontaneous-emission (SE) broadband light source combined with a polarimetric interferometer, all wavelengths are available simultaneously within the spectrum range in use. This means the system only needs a few seconds to accurately acquire data for further PMD analysis.
