Backbone DWDM Systems

The compact SpectralWave DW4200 offers flexible multiplexing and transport on long-haul and ULH platforms. Leading features include full ROADM capabilities, 400Gbit/s transmission on an ETSI rack and the supreme reliability of path-based protection.

Service providers can remotely and rapidly reconfigure optical paths in their DWDM networks with the DW4200 ROADM. Time-saving and cost-effective, it allows wavelengths to be added or dropped remotely, at any node, to swiftly create end-to-end optical paths.

The DW4200 ROADM supports up to 40 wavelengths in C band or L band. Since capacity can be expanded to 80 channels per band, service providers can flexibly design optical networks without worrying about upgrading and reconfiguring the network to meet future traffic demands.

New revenue services like bandwidth on demand are supported, as well as generalized multi-protocol label switching (GMPLS), wavelength cross-connect (WXC), SDH on a card, and other functions that enable multi-layer management and better compatibility with other network elements.
