Infinera's mission is to earn a superior return by enabling our customers to build and operate the world’s best optical networks. We do that by delivering on our founding vision of enabling an infinite pool of intelligent bandwidth that the next communications infrastructure is built upon. Today Infinera is well known in the technology segments of optical WDM transport and digital OTN switching for its award-winning DTN-X platform. Infinera is enhancing the platform 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 MPLS services with QoS from the edge of their networks to core transport services creating highly efficient packet-optical network architecture.
