A consortium that includes RTI Connectivity Pte. Ltd. (RTI-C), AARNet Pty Ltd (AARNet) and Google, together with Alcatel Submarine Networks (ASN), part of Nokia, and NEC Corporation (NEC) announced that construction of the 9,500-km-long Japan-Guam-Australia Cable System (JGA) has officially begun.

A press release said that the undersea fiber optic cable system, designed for capacity of more than 36 terabits per second (Tbps), is expected to be completed in the fourth quarter of 2019.
JGA is being co-built by ASN and NEC. JGA South (JGA-S), the segment between Sydney, Australia and Piti, Guam, is a consortium cable including AARNet, Google and RTI-C. JGA North (JGA-N), the segment between the Minami-Boso, Japan and Piti, Guam, is a private cable with RTI-C as the sole purchaser. Both JGA-N and JGA-S will interconnect in Guam at GTA’s newly built landing station.

“We are honored to be selected once again by RTI-C to construct their third subsea cable,” said Toru Kawauchi, general manager of NEC’s Submarine Network Division said. “While both SEA-US and HK-G will provide horizontal East-West connectivity across the Pacific, JGA will now provide the much-needed vertical North-South connectivity, enabling high capacity communications to reach all corners. Further, JGA will be the second project after HK-G to be co-financed by the Japanese government-led Japan ICT Fund, and the third project supporting RTI’s investment after SEA-US and HK-G for the Japanese loan syndicate. We wish to further utilize these funds for many more cables in the future.”

JGA will further enhance and contribute to the much-needed expansion of communications networks from Japan and Australia, to Asia and the U.S., the release said. That, it noted, will improve network redundancy, ensuring highly reliable communications and expanding onward connectivity options in Guam.
