To meet the growing demand for internet traffic and digitization, strengthen the construction of network infrastructure in Asia, and promote interconnectivity, Asia Direct Cable System (hereinafter referred to as ADC submarine cable) is committed to providing high-speed and stable submarine communication networks in the Asia.

Optimize network layout, promote "Belt and Road" cooperation

To actively promote international cooperation under the Belt and Road Initiative, improve the connectivity of international communications infrastructure, meet the growing demand for international bandwidth in the Asia-Pacific region, and optimize the layout of international communications networks, China Telecom Group Co., LTD. (hereinafter referred to as China Telecom) and China United Network Communications Group Co., LTD., together with six major overseas operators, jointly launched the construction project of the Asia direct submarine cable system. The construction of ADC submarine cables significantly promotes economic cooperation and development in Asia and provides people with reliable network access services.

Cross Asia, super large submarine cable capacity, consolidating the interconnection hub position of nodes along

The ADC Submarine Cable project, led by China Telecom, is a high-capacity international submarine cable project connecting China, Japan, Singapore and major countries and regions in the Asia-Pacific region. The total length is about 9,600 kilometers, and it will be equipped with eight fiber pairs, carrying more than 140 Tbps of traffic. Stretching from Batangas in the Philippines to Tuas in Singapore, Chung Hom Kok in Hong Kong, China, Shantou in Guangdong, China, Marushan in Japan, Qui Nyan in Vietnam, and Seracha in Thailand, the project is expected to be completed in the first quarter of 2024.

In November 2022, the Philippine PLDT announced that the ADC submarine cable had landed at the nasugbu submarine cable landing station in Batangas Province of the Philippines.

On January 12, 2023, China Telecom Global and the NEV Group, the No.1 data center service provider and connectivity hub in Hong Kong, jointly announced that the Hong Kong section of the ADC Submarine Cable System has successfully landed on NEV's HKIS-1 in Chung Hom Kok, and set up a new undersea fiber optic network contact point with the super large-scale datacenter MEGA Plus.

Multi-party cooperation and diversified investment methods reduce risks, and new technologies improve the efficiency and stability of the submarine cable system

The construction of the ADC submarine cable system has been actively supported and cooperated by governments, operators, equipment manufacturers, and other partners. Such a collaborative approach has accelerated the construction and promotion of submarine cable systems The ADC submarine cable system is jointly invested by several operators. This diversified investment methods reduces investment risks, promotes project construction and operation, and enhances project implementation's feasibility and success rate.

Secondly, the ADC submarine cable traverses multiple countries and regions, enabling direct communication between Asia-Pacific countries. This way of trans-continental joint construction is innovative in the field of international communication, which can significantly improve the efficiency of communication and reduce the cost of communication.

Finally, from the technical point of view, ADC submarine Cable adopts the latest communication technology, including large-capacity, high-rate optical transmission technology and intelligent network management technology, such as the industry's advanced multi-fiber Open Cable mode, the design capacity of a single fiber pair can reach more than 16Tb/s. The application of this technology significantly improves the transmission efficiency and network stability of the submarine cable system.

Meeting customer business needs, improving overall network security in the Asia Pacific region, and reducing operating costs

In recent years, the Internet industry has developed rapidly. With the application of 5G networks, loT, Al, cloud, video, and other applications, the demand for international bandwidth has proliferated, especially between the Chinese Mainland, Hong Kong, Singapore, and Japan. ADC submarine cable construction can meet the growing business needs.

Some sections of the current APCN2 and SJC submarine cables are similar in routing and have been affected by seismic zones with many blocking failures in history. ADC submarine cable can realize load sharing of more routes and improve the overall security in the Asia-Pacific region.

Finally, China Telecom believes that the application of new technologies can significantly reduce the unit bandwidth cost within the Asia-Pacific region after the submarine cable is launched, enhance the competitive advantage of ADC submarine cables in the international market, and reduce network operating costs.
