Service provider DWDM relates to systems used in core networks that increase the number of channels transmitted on a fiber optic cable by up to 80 times. Ethernet aggregation routers and switches that revitalize DWDM markets are supplementing transport systems.

Fully non-blocking switching architecture provides bandwidth management capabilities and service modules. These enable high-density service termination without stacking multiple shelves. Optical metro DWDM series portfolios of products are equipped with resilient packet ring technology, generic framing protocol service mapping, and virtual concatenation that enables efficient bandwidth utilization with native rate client data and storage interfaces.

Vendors offer equipment, software and service that allow customers to combine disparate networks that support distinct voice, video or data services, to a more efficient, converged, multiservice communications network. Transport, switching and aggregation products enable network convergence and offer standards-based, software-driven automation of network functionality.

Through the automation of network functionality and convergence are supported equipment. Customers can simplify the construction and management of their communications networks, and improve their operating efficiency and cost effectiveness.
