HKA

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:

• Main Trunk, six fiber pairs connecting Chung Hom Kok in Hong Kong SAR and Hermosa Beach, China Telecom and China Unicom each owns one fiber pair, RTI, Tata and Telstra each owns a half fiber pair, Facebook owns two and half fiber pairs. 
• Toucheng Branch, with six fiber pairs, two owned by Telstra and four owned by Facebook.
• Manchester Branch, with two fiber pairs wholy owned Facebook.
• Hermosa Beach Branch, with six fiber pairs, China Telecom and China Unicom each owns one fiber pair, RTI, Tata and Telstra each owns a half fiber pair, Facebook owns two and half fiber pairs.

China Telecom controls the cable landing station in Chung Hom Kok (GB21), Telstra controls the cable landing station in Toucheng.

Facebook is the landing party in the US, controls the Mancherster cable landing stations and the Hermosa Beach cable landing station (which is owned by RTI Infrastructure). Facebook will have exclusive control over the PFE located in RTI-I’s Hermosa Beach cable landing station, retain operational authority over the HKA landing facilities at Hermosa Beach and provide direction to RTI-I in all matters relating to the HKA system. The SLTEs for all of the HKA cable system’s fiber pairs will be installed at CoreSite’s One Wilshire and Wilshire Annex data centers in Los Angeles.
