NTT Communications Corp.(NTT Com) announced this week it has expanded the data-transmission capacity of its Global IP Network between Japan and the United States to 600 gigabits per second (Gbps). The new capacity is equivalent to approximately 35,000 channels of digital terrestrial television or more than five centuries’ worth of content in a daily newspaper.

NTT Com’s global IP backbones are connected to fixed and mobile telecom companies, Internet service providers (ISPs), data centre operators and content providers.

“Although a part of the cable was damaged following the March 2011 earthquake, it was quickly repaired with minimum disconnection,” the company said in a release. “This was thanks to the fully redundant cable structure and collaborative efforts with multiple carriers and cable companies, based on an established cooperative relationship.”

Demand for high-capacity bandwidth has been growing rapidly in recent years, reflected in the seven-fold increase in NTT Com’s Japan-U.S. bandwidth between 2005 and 2010.
