The AAG consists of two fiber pairs from Hong Kong to Hawaii via the Philippines and Guam, three fiber pairs from Hong Kong to Singapore with branching units to Vietnam, Brunei, Malaysia, and Thailand, and three fiber pairs from Hawaii to the US west coast.

The AAG cable system was initially designed with 96*10Gbps DWDM technology, with a minimum system capacity of 1.92 Tbps. The AAG cable system was supplied by ASN and NEC, with a total cost of about US$560 million, completed and ready for service on November 10, 2009. In 2011, the AAG cable system was upgraded with 40Gbps DWDM technology and increased system capacity up to 5.2 Tbps. And it was further upgraded with 100Gbps DWDM technology in 2014.
