Infinera, a provider of Intelligent Transport Networks, announced new platforms within its DTN-X Family to power cloud scale subsea networks. The company 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 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. The new tools enhance Infinera’s open and programmable subsea network architecture, enabling operators to securely monetize their subsea spectrum.
Trans-Atlantic bandwidth is forecast to grow at 40 percent annually through 2025, with the majority of this traffic shifting to private networks according to analyst Telegeography. This private traffic is dominated by N x 100 Gb/s “elephant flows” travelling between the data centres of internet content providers as they move content around the globe.
Infinera’s new solutions
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 for enhanced capacity and reach. The industry’s first 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.
DTN-X XTC Series upgrade The 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.
New subsea software tools Dynamic spectral sharing enhances Infinera’s open architecture, allowing subsea operators to partition and monetise fibre 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.
Scott Jackson, VP Subsea Business Group at Infinera, commented, “The new capabilities announced today deliver leading capacity and reach, and provide the tools essential for cloud scale subsea networks. We are pleased to show our investment in the subsea market, with solutions enabling operators to rapidly and cost-effectively deliver scalable services across open networks.”
Larry Schwartz, Chief Executive Officer at Seaborn Networks, added, “Our flexible business model enables customers to rapidly expand wholesale capacity on submarine cable networks. The new XTS-3300 and XTS-3600 meshponder solutions and dynamic spectral sharing are ideal for subsea networks to ensure scalability, flexibility, programmability and rapid activation of bandwidth.”
