NTT Communications scales Japan-U.S. network capacity beyond 1 Terabit

NTT Communications continues to scale the speed of its global network, announcing that the capacity on its Japan to United States route surpassed 1 Tbps this month.

The service provider claims this marks the first time a Japan-U.S. network reached that speed.

By having this new capacity on hand, NTT said it will be able to support the forecast demand for capacity that it expects to see double over the next two years due to the growing number of Internet users on mobile smartphones and tablets and the growing adoption of broadband.

It offers services via its global IP network to Japan and major countries in Asia, North America, Latin America, Europe and Oceania. The Asia-Oceania channel has reached a total capacity of over 1.5 Tbps, while the Japan-U.S. channel handles over 1 Tbps.

Being a forward-looking service provider, NTT Communications said it has been making new investments in a number of new technologies, including 100 Gigabit Ethernet (GbE) and and 100G digital coherent transmission, a next-generation optical transmission technology on the PC-1 submarine cable.

In March, NTT completed a field trial of 400 Gbps optical signals on its existing network without affecting existing 100G channels as it added and removed 400G channels in a 100G WDM system.

It plans to take the result of that trial to establish optical transport systems, including optical fiber cables, and apply them commercially for a number of uses such as 400 Gbps technology and other flexible optical network technology and Ethernet technologies, including 400 GigE to compose 400 Gbps optical signals.
