ADVA Optical Networking – Wavelength Division Multiplexing (WDM) is the foundation of todays carrier networks integrating both legacy and next-generation, carrier-class Ethernet/IP services across all tiers of the network. WDM offers low-cost transport for all applications and services, scales easily in terms of capacity and reach and provides rapid protection against any fiber plant failure. Fully transparent to any bit rate and protocol, WDM is the natural, multi-service integration layer for modern networks rendering them more manageable, more efficient and more capable of delivering the tremendous volumes of bandwidth required for the emerging class of business and consumer services
