Infinera’s DTN-X XTC Series has won several industry accolades for its scale, flexibility and programmability. Infinera has now further enhanced the DTN-X XTC Series with the introduction of the PXM, a packet switching module that provides advanced packet features and quality of service (QoS) capabilities. It enables service providers to directly map Ethernet and Multi-Protocol Label Switching (MPLS) packet services with QoS from the edge of their networks to core transport services over digital Optical Transport Network (OTN) and optical super-channels, creating a highly efficient packet-optical network architecture. Service providers can now benefit from the efficiencies of statistical multiplexing with packet aggregation and transport port consolidation. They can also improve their revenues with an augmented portfolio of highly reliable Metro Ethernet Forum (MEF) Carrier Ethernet 2.0 (CE 2.0)-certified services. The Infinera DTN-X XTC Series is now the most comprehensive software-controlled core transport solution with converged packet, digital and optical functionality.
