The Hong Kong-America Cable System（HKA）is a 6-fiber-pair submarine cable connecting Hong Kong and the U.S. directly, with initial design capacity of 12.8 Tbps per fiber pair (for a total of 76.8 Tbps) using 100Gbps coherent DWDM technology.
The HKA Consortium consists of Facebook, China Telecom, China Unicom, RTI Express, Tata Communication and Telstra. The HKA supply contract is awarded to ASN. The HKA Consortium and ASN officially announced the launch of HKA cable project at PTC 2018.
The HKA cable system consists of a main trunk and three branching units:
China Telecom controls the cable landing station in Chung Hom Kok (GB21), Telstra controls the cable landing station in Toucheng, Facebook controls the Mancherster cable landing stations and the Hermosa Beach cable landing station (which is owned by RTI Infrastructure).
