NTT Communications has confirmed the commercial viability of 100Gbps optical transmission on its PC-1 trans-Pacific submarine cable, following successful trials completed in October.

The company confirmed it expects to deploy the technology on the cable by mid-2013, which it believes will increase the cable’s transmission capacity to 10Tbps, tripling existing capacity of 3.2Tbps. The cable, which links Japan and the US, taps in to all transpacific cable routes and is primarily used to deliver global-IP network services and global cloud services.

“Our subsea cable system PC-1 is an important international communications for the US and Japan as proven during the March 11 disaster (Japanese earthquake and tsunami),” said Takahiro Sumimoto, CEO of PC Landing Corp, a NTT Com held company and subsea cable operator. “Enhancing our capabilities of this PC-1, which provides the transpacific shortest link, through the most advanced technologies will satisfy ever increasing traffic and will be extremely beneficial for users.”

NTT Com said the increasing use of cloud computing, in addition to data demand through smartphone and tablet devices have led to an upgrade to the cable.
