The Hong Kong-Americas (HKA) consortium and Alcatel Submarine Networks (ASN) have signed a turnkey contract for the deployment of the Hong Kong-Americas (HKA) submarine cable network, which will span more than 13,000 kilometers.

This new open cable system will increase connectivity between Hong Kong and the US and will reinforce Hong Kong’s role as a key communications hub in the Asia-Pacific region. The HKA consortium includes China Telecom, China Unicom, Facebook, Tata Communications, and Telstra as the major parties.

The HKA system will feature six fiber pairs and will connect Chung Hom Kok in Hong Kong to Hermosa Beach in California; additional connectivity options may be exercised in future. Its open design will deliver significant cost benefits as well as enhanced bandwidth availability for telecommunications services and content-based services between Asia and North America. Target completion date for the HKA System is in the year 2020. 

Chung Hom Kok Cable Landing Station is located at Chung Hom Kok in the central island of Hong Kong and is the southernmost cable landing station in Hong Kong. Three cables of the C2C Network land at the Chung Hom Kok Cable Landing Station. In addition, the Southeast Asia Japan cable system lands at this station. The station is owned by Pacnet (Telstra) with Pacnet and China telecom Global providing backhaul.

Leveraging its state-of-the-art subsea technology, the ASN solution will deliver greater diversity of connections, enhanced reliability and network efficiency, as well as enabling optimal connectivity between major data centers in Asia and the USA.
The solution includes ASN's submarine WSS ROADM units, the latest generation of repeaters and will offer high performance and powering resilience, enabling over 80Tb/s transmission capacity. In addition, it is also compatible with future generations of submarine line terminal equipped with Probabilistic Shaping technology.

Philippe Piron, President of Alcatel Submarine Netwoks, said: "We are proud to work with the HKA consortium on this project, which incorporates several innovations from ASN and will be based on the latest high-performance submarine line design. The trust placed upon us by the HKA consortium validates our position as a key player for submarine network infrastructures in the Asia-Pacific region and the reinforcement of our local presence.”

Piron added: “It also provides a strong platform to further demonstrate our commitment in project management and in the development of local relationships to support operators and content providers for their network and capacity expansion strategies."

Telstra said it would invest in a half fiber pair on the Hong Kong Americas (HKA) cable. Telstra said it would also purchase capacity equivalent to 6 terabits per second on the Pacific Light Cable Network (PLCN), which like HKA will stretch from Hong Kong to the west coast of the US. Google and Facebook are also backing the PLCN.

The PLCN will have a total capacity of around 120 terabits per second and include 12,800 kilometers of fiber. The cables will offer lower latency than the Asia-America Gateway (AAG), which connects South-East Asia to the west coast of the US via Guam and Hawaii.

“Together with the current AAG cable on which Telstra carries the most traffic today, these two investments will provide us with increased capacity across the important Hong Kong to US route, one of the fastest growing routes in the world for capacity demand,” Telstra’s group managing director of global services and international, David Burns, said in a statement.
