TOKYO, JAPAN --- NTT Communications Corporation (NTT Com), the ICT solutions and international communications business within the NTT Group, announced today that they will begin deploying an ultra-large-capacity, space-saving and energy-saving 400Gbps (400G) optical transmission system in data centers for network connection. Deployment will be implemented sequentially from April 14th.
The system will raise the transmission capacity of NTT Com’s core network above 19Tbps per optical fiber, or more than double existing capacity.
The system utilizes the advanced digital-signal processing technology which is the result from Nippon Telegraph and Telephone Corporation (NTT)’s R&D.
Going forward, NTT Com and NTT will jointly investigate further possibilities, including the deployment of PoC to deliver high-speed Ethernet signals, including 400GbE. Mindful of IEEE standardization trends, they will pursue increased flexibility and agility for transmission networks by leveraging dis-aggregated equipment and SDN technologies.
NTT Com achieved its existing 100Gbps-per-channel optical transmission system through the early adoption of digital coherent optical transmitting technology in response to rapidly increasing traffic on its core optical fiber network, as well as expanding video data and cloud services. NTT Com has now taken practical steps to upgrade to 400G transmission technology due to ever-increasing network demands for higher speeds and more data, including for 4K/8K and other high-resolution video data, the full-fledged expansion of IoT and big-data processing.
NTT Communications provides consultancy, architecture, security and cloud services to optimize the information and communications technology (ICT) environments of enterprises. These offerings are backed by the company’s worldwide infrastructure, including the leading global tier-1 IP network, the Arcstar Universal One™ VPN network reaching 196 countries/regions, and over 140 secure data centers worldwide. NTT Communications’ solutions leverage the global resources of NTT Group companies including Dimension Data, NTT DOCOMO and NTT DATA.
