The Asia-Pacific Gateway (APG) is a 10400km submarine cable system linking 8 countries and regions in Asia region, i.e., Malaysia, Singapore, Vietnam, Hong Kong, Taiwan, Mainland China, Japan, and Korea.

The APG cable system consists of 6 fiber pairs in the trunk, initially designed with 128*40 Gbps DWDM technology and system capacity of 30.72Tbps, upgradable to 100 Gbps wavelength. APG consortium announced the system capcity as 54.8Tbps based on different calculation.

When it was initiated in May 2009, the APG consortium included PLDT(the Philippines), Chunghwa Telecom(Taiwan), China Telecom and China Unicom (mainland China), KT Corp. (South Korea), NTT Communications (Japan), Telekom Malaysia (Malaysia), and VNPT (Vietnam). PLDT and Telekom Malaysia were dropped off to participate in the ASE consortium.

APG, ASE  and SJC are three submarine cables on the Japan-Hong Kong-Singapore route. 

NTT Com, PLDT, StarHub and Telekom Malaysia comprise consortium members of the Asia Submarine-cable Express (ASE). While KDDI, SingTel, China Telecom, China Mobile, Globe Telecom and Google team up for the South-East Asia Japan Cable (SJC).

On December 20,2011, the APG consortium which includes Chunghwa Telecom, KT and NTT and other members signed in Beijing the APG C&MA. But the APG C&MA was not effective until early July 2012 when Facebook and Time dotCom were enrolled to form the final 12-member APG consortium, including China Mobile, China Telecom, China Unicom, Chunghwa Telecom, Facebook, KT Corp, LG Uplus, NTT Communications, StarHub, Time dotCom (Global Transit)  Viettel and VNPT.

APG consortium selected NEC as the system supplier. The total cost of APG cable system is approximately USD560 million (inclusive of landing cost).

The APG cable system has been ready for service as of Oct 28, 2016.
