NEC and RTI-C start construction of HK-G subsea cable

24 April 2017 | James Pearce


NEC and RTI-C have begun construction of the HK-G subsea cable that will link Hong Kong and Guam with 100Gbps optical transmission capabilities.

The 3,900km Hong Kong – Guam Cable will offer 48Tbps design capacity and is expected to be completed in Q4 2019. It will run from Tseung Kwan O in Hong Kong to the recently finished Teleguam Holdings landing station in Piti.

The cable is in part funded by capital from the Fund Corporation for the Overseas Development of Japan’s ICT and Postal Services (Japan ICT Fund), along with syndicated loans from Japanese institutions including NEC Capital Solutions Limited, among others.

Russ Matulich, RTI-C's president and CEO, said: "Hong Kong is already an important interconnection point for undersea cables, and Guam is emerging as a key telecommunications hub. By extending HK-G to our SEA-US cable investment in Guam, RTI-C is facilitating a new diverse 100G transpacific cable to better serve our customers' traffic requirements between Asia, the United States and Australia. 

"RTI-C's existing investments, and those under current consideration, will enable other cable owners to better utilize their assets by interconnecting with RTI-C in Hong Kong or Guam."

In Guam, it will connect with the SEA-US system which is currently under construction by NEC, and will link the US directly to South East Asia.

NEC won the deal to construct the HK-G cable in January. It is the latest build for the Japanese company, which completed construction of the Asia Pacific Gateway cable system between Japan and Singapore in November.

Toru Kawauchi, GM of NEC's submarine network division said: "NEC has completed nearly all of the cables that land in Hong Kong and Guam, and I am proud to be part of this latest system. 

“HK-G will be the first project to be co-financed by the Japanese government-led Japan ICT Fund, and the second project supporting RTI's investment in SEA-US for the Japanese loan syndicate. We wish to further utilize these funds for many more cables in the future."
