DTN-X Multi-Terabit Packet Optical Network Platform

Are you ready for the Terabit Era? The Infinera DTN-X platform family is. Built upon the design principles of the highly successful Infinera DTN platform, the Infinera DTN-X P-OTN platform brings the scale, simplicity and efficiency of the Intelligent Transport Network into the Terabit Era. Featuring large scale Photonic Integrated Circuits (PIC), built-in digital OTN switching with 1 Gb/s granularity, GMPLS based network intelligence that enables dynamically protected mesh networks and Transport SDN, the DTN-X delivers the next step function in networking. The DTN-X was designed with investment protection in mind, including programmable coherent technology so operators can optimize their fiber assets, scaling to 5 Tb/s per bay today, and to 1.2 Tb/s of slot capacity allowing 12 Tb/s per bay and 240 Tb/s in a multi-bay configuration in the future. Finally, this converged DWDM transport, digital packet-OTN switching platform consumes less power and less space to deliver frugal network economics without compromising the ability of the network to achieve its full potential.

The major features of the platform are:

  • Scale
    • PIC-based FlexCoherent super-channel WDM
    • Multi-terabit, non-blocking digital OTN cross connect
  • Simplicity
    • Plug and play automation, GMPLS intelligence, open SDN interfaces
    • Functional convergence of optical WDM and digital packet-OTN switching
  • Efficiency
    • Lower power and space consumption than comparable solutions
    • Bandwidth Virtualization to ensure maximum usage of all available bandwidth


Next-gen Multi-terabit P-OTN

DTN-X Features
500 Gb/s large scale Photonic Integrated Circuits Ensures most economical, highest density DWDM platform while dramatically reducing space & power needs so that other functions can be enabled without any performance compromise.
Ethernet and MPLS capability Directly map Ethernet and MPLS services with QoS from the edge of your networks to core transport services creating highly efficient packet-optical network architecture.
Carrier Ethernet Services Take advantage of the efficiencies of statistical multiplexing with transport port consolidation and by improving revenues with an augmented portfolio of highly reliable MEF-compliant Carrier Ethernet services.
500 Gb/s large scale Photonic Integrated Circuits Ensures lowest cost, highest density DWDM line system while dramatically reducing space & power needs so that other functions can be enabled.
Built-in digital OTN switching at every node with a switching granularity of ODU0 (1 Gb/s) Why pay extra for external switches when this capability is already built in? The Infinera DTN-X optimizes network efficiency by grooming all traffic at every location in the network.
PIC-based FlexCoherent super-channel platform The DTN-X features a PIC-based coherent super-channel architecture, based upon 500G super-channels today, and designed to support 1.2 Tb/s super-channels in the future. Super channels extract the maximum fiber capacity without requiring a move outside of the C-band.
Unconstrained add/drop in any direction enabling a colorless, directionless and contention-less ROADM Free your network planning from traditional network constraints, and let the network realize its maximum potential. Any service, any color, any direction with zero blocking and zero constraints.
Non-blocking switching fabric scales to 240 Tb/s An architecture that features a separate switch fabric, so transport and switching are unconstrained to grow in any direction. With multi-chassis configurations, the switch scales to 240 Tb/s.
Plug and play automation Digital automation reduces OpEx by eliminating traditional implementation steps including hundreds of operational steps, patch fibers and site visits required for analog optical systems.
Embedded network intelligence Drive down operating costs with GMPLS technology for:

  • Automatic topology discovery & inventory management
  • Point and click end-to-end service provisioning
  • Sub-50ms hardware based protection for various topologies with Infinera FastSMP™ (Fast Shared Mesh Protection)
  • Optical/IP integration via an Optical UNI
Open, standards-based SDN interface The Infinera Open Transport Switch (OTS) software with open Web 2.0 API for the DTN-X provides abstraction to offer a real-time on-demand programmable bandwidth service model. It allows providers to deliver innovative services and automate their operations while enabling optimal resource utilization within a multi-layer network.
Success-oriented business model for network expansion Infinera Instant Bandwidth™ enables operators to rapidly deploy bandwidth in 100 Gb/s increments without having to deploy and install additional line cards in the system. It offers transport operators the ability to rapidly provision additional 100 Gb/s capacity thus allowing them to differentiate their services by shortening provisioning times, accelerating service delivery, and reducing time to revenue.
