NTT Com's Transpacific Cable Sees 100G Upgrade in 2013

NTT Communications confirmed that it will deploy 100 Gbps coherent transmission technology in its PC-1 transpacific submarine cable system by the middle of 2013. The upgrade will boost the PC-1's transmission capacity to 10 terabits per second (Tbps), more than triple its current capacity of 3.2 Tbps.

"Our subsea cable system PC-1 is an important international communications for the United States and Japan as proven during the March 11 disaster. Enhancing the capabilities of this PC-1, which provides the trans-pacific shortest link, through the most advanced technologies will satisfy ever increasing traffic and will be extremely beneficial for users." said Takahiro Sumimoto, CEO of PC Landing Corp.

PC Landing Corp., an NTT Com group company and operator of the PC-1, succeeded in a trial 100 Gbps optical communication transmission using digital coherent technology in October. The trial, conducted over more than 9,500 kilometers of PC-1 fiber, was supported by the PC-1's optically optimized architecture including efficiently placed optical repeaters and optical fiber layout.

  • In October 2011, Infinera and Pacific Crossing, a wholly owned subsidiary of NTT Communications, have completed a 100 Gbps trial using the PC-1 transpacific submarine cable system. The test spanned more than 9,500 kilometers from California to Japan.

    Infinera said this trial demonstrates the unique ability to deliver two industry firsts. The 100 Gigabit Ethernet (GbE) demonstration was the first transmission of a 100 GbE client service carried across the Pacific using 40 Gbps optical channels with Infinera's FlexCoherent transmission. The success of this trial was based on Infinera's commercially available 40 Gbps optical line module and 100 GbE client interface on Infinera's DTN platform.

    The second demonstration was the first realization of a 100 Gbps optical channel using binary phase shift keying (BPSK) with soft decision forward error correction (SD FEC) that will be available in the future on Infinera's DTN-X platform. Infinera's FlexCoherent technology enables service providers to optimize transmission performance across a range of applications using multiple software-programmable modulation formats. Infinera recently announced the availability of new DTN capabilities and the new DTN-X platform featuring both photonic integrated circuit (PIC) based super-channels and FlexCoherent transmission.
