The JDS Uniphase WD1515AD2K-NT1 is a high-performance Dense Wavelength Division Multiplexing (DWDM) Add/Drop Filter module engineered for wavelength management in telecommunications infrastructure. It selectively adds or drops specific optical channels from a WDM signal while passing remaining channels with minimal loss and high isolation. The module supports both 100 GHz and 200 GHz ITU grid spacing with configurable channel counts of 1, 2, 4, or 8 channels, making it suitable for long-haul, metro, and access network deployments.
