The Hong Kong-Guam (HK-G) cable system is a 3,700 kilometer undersea cable connecting Tseung Kwan O (TKO), Hong Kong and Piti, Guam.
RTI (through its multiple affiliates RTI Solutions, Inc, RTI HK-G PTE. LTD., and RTI Connectivity PTE. LTD) and Google (through its indirect subsidiary GU Holding Inc) are the joint builders of the HK-G cable system.
The HK-G cable system consists of 4 fiber pairs, with design capacity of 48 Tbps (12 Tbps per fiber pair).
Google owns approximiately two thirds of a fiber pair on the HK-G cable system via spectrum sharing technology. RTI HK-G owns all the remaining capacity and fiber pairs.
RTI Connectivity controls RTI HK-G’s interests in the HK-G system through its role as Asset Manager of RTI HK-G. RTI Connectivity was appointed RTI HK-G’s Asset Manager through an Asset Management Agreement by and between the two companies.
RTI Solutions serves as the U.S. landing party and control the Guam landing arrangements for the HK-G system under a contract with the cable landing station owner, Gateway Network Connections LLC ("GNC"), a Guam limited liability company that is 51 percent owned by Asia Connectivity Elements, Inc. (“ACE”), a Guam corporation, and 49 percent owned by TeleGuam Holdings, LLC (“GTA”).
RTI HK-G serves as Hong Kong landing party to land the cable at NTT's TKO Cable Landing Station and data center in Hong Kong.
NEC was awarded the supply contract for the HK-G cable system. Furthermore, HK-G cable system utilizes capital from the Fund Corporation for the Overseas Development of Japan’s ICT and Postal Services Inc. (Japan ICT Fund), along with syndicated loans from Japanese institutions including NEC Capital Solutions Limited, etc.
In November 2020, HK-G joint builders withdrew from the FCC their application for a license to construct, land, and operate the HK-G submarine cable system connecting the United States and Hong Kong.
