NTT Com, the ICT solutions and international communications business within the NTT Group, announced 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 mid this month.
The system will raise the transmission capacity of NTT Com’s core network above 19Tbps per optical fiber, or more than double existing capacity, said the company.
The system utilizes the advanced digital-signal processing technology which is the result from NTT’s R&D. The 400G system featuring top-level energy and space savings feature, can reduce energy consumption per bps by 75% and space requirements by 80% compared to the existing system.
To deliver new services and functions with even greater speed and flexibility, NTT Com said it will combine SDN technologies and dis-aggregation architecture, which can be redeployed as required according to function or module, replacing existing high-function, all-in-one dedicated equipment.
Going forward, NTT Com and NTT will jointly research further possibilities, including the deployment of PoC to deliver high-speed Ethernet signals e.g. 400GbE.
