Infinera announced new platforms within the DTN-X Family to power cloud scale subsea networks. Infinera introduced the XTS-3300 and XTS-3600 meshponders for subsea networks, and upgraded its DTN-X XTC Series to 12 terabits per second (Tb/s) of non-blocking Optical Transport Network (OTN) switching with a new 1.2 Tb/s subsea line card. The solution features dynamic spectral sharing and access to real-time subsea link performance. These new tools enhance Infinera's open and programmable subsea network architecture, enabling operators to securely monetize their subsea spectrum. Infinera’s new solutions for subsea network operators include: DTN-X XTS-3300 and XTS-3600 meshponders. The compact 1 rack unit (1RU) and 4RU plug-and-play subsea platforms integrate the performance of the Infinite Capacity Engine with the Advanced Coherent Toolkit (ACT) for enhanced capacity and reach. The meshponders combine 2.4 Tb/s super-channels with sliceable photonics and in-flight line-rate Layer 1 encryption in a compact and lower-power form factor. They support Infinera’s unique Instant Bandwidth capability, providing rapid bandwidth management and service provisioning for success-based growth. The XTS Series features long-reach subsea-optimized modulation formats providing best-in-class capacity, as well as the industry’s first commercially available Nyquist subcarriers to improve transmission performance and soft-decision forward error correction (SD-FEC) gain sharing to maximize capacity. The new platforms seamlessly interoperate with Infinera’s DTN-X XTC and XT Series, providing a unified end-to-end Intelligent Transport Network portfolio that enables end-to-end services covering subsea, long-haul, metro and data center interconnect applications. DTN-X XTC Series upgrade. The Infinera DTN-X XTC-4 and XTC-10 have been upgraded with subsea-optimized and Instant Bandwidth-enabled 1.2 Tb/s line modules. The XTC-4 and XTC-10 platforms now have more than twice the switching and transmission capacity, enabling up to 12 Tb/s of OTN switching via non-disruptive in-service upgrades. The new line modules coexist with previously deployed modules, thereby protecting prior investments in DTN-X platforms. The DTN-X XTC Series now offers up to 12 Tb/s of non-blocking switching capacity with ODU0-level switching granularity in a single unit, and unlike competitive systems, has no tradeoffs between client-side tributary capacity and line-side capacity. New subsea software tools for open systems. Dynamic spectral sharing enhances Infinera’s open architecture, allowing subsea operators to partition and monetize valuable fiber spectrum so that it can be securely shared with multiple tenants, independent of both cable and submarine line terminal equipment suppliers. Mission-critical subsea link performance data is available in real time, on-demand, via open software-defined network application programming interfaces. This enables subsea operators to monitor transmission health as well as identify opportunities for capacity adjustments. In addition to these new tools, Infinera's Time-based Instant Bandwidth enables operators to instantly change network capacity as well as duration, facilitating a dynamic Intelligent Transport Network. Now operators can closely match traffic patterns to address bursty service demands from customers, match bandwidth to revenue, and instantly reroute bandwidth in the case of network disruptions.
