The Swept Wavelength System SWS2000 series remains the industry standard solution for measuring insertion loss (IL), polarization dependent loss (PDL), return loss (RL) and directivity with high wavelength resolution in both research and development (R&D) and production environments. Currently used at more than 80 customer sites, with over 8500 detector channels deployed, the SWS test platform validates optical performance for the latest in optical components and modules including: ROADMs, Wavelength Switches, Tunable Filters and Circuit Packs. The SWS system consists of a tunable laser source, a source optics module (SOM), a control module, a receiver chassis, one or more detector modules and application software.
