On 24th March, the launch ceremony of ADC Submarine Cable’s commissioning was successfully held at the Everbright Centre in Hong Kong. The event brought together over a hundred distinguished guests, welcoming prominent figures from the political and business sectors, industry experts, and representatives from media organisations.
The ADC Submarine Cable project is jointly constructed by China Telecom, China Unicom, Singapore Telecom, Japan’s SoftBank, TATA Communications, Vietnam’s VIETTEL, Thailand’s NT, and the Philippines’ PLDT.
As the only international submarine cable initiative launched in the Asia-Pacific region over the past nine years, it boasts the highest system transmission capacity and the largest number of fibre pairs in the region. Spanning 9,988 kilometres, the ADC Submarine Cable links mainland China, Hong Kong, Japan, Singapore, and multiple other countries and regions across the Asia-Pacific.
Designed with an open cable architecture and cutting-edge high-capacity optical transmission technology, it features a per-fibre pair design capacity exceeding 20 Tb/s, with a total system capacity surpassing 160 Tb/s. By offering diverse routing options, the ADC Submarine Cable notably strengthens network resilience and stability across the Asia-Pacific, reinforcing the region’s digital infrastructure.
At the event, Prof. Sun Dong, Secretary for Innovation, Technology and Industry, the Government of HKSAR, emphasised that as a key gateway for the country’s opening-up, Hong Kong will fully harness its unique advantages under the “one country, two systems” framework. Leveraging its strategic roles as a “super connector” and “super value-adder,” Hong Kong aims to facilitate the global expansion of mainland enterprises while attracting international businesses.
The Hong Kong SAR Government remains committed to enhancing the innovation and technology ecosystem through institutional innovation, policy coordination, and international collaboration.
Ms. Liu Ying, Executive Vice President of China Telecommunications said that the official launch of the ADC Submarine Cable marks a significant milestone in international cooperation. This achievement not only reaffirms China Telecom’s long-standing commitment to its global expansion strategy, Cloud-network integration, and digital transformation but also ushers in a new era of collaboration with global partners to drive technological progress and shared prosperity.
As one of the organisers of the ADC Submarine Cable project, Mr. Yin Jin, CEO of China Telecom Global stated that the ADC Submarine Cable will add over 50 Tb/s of bandwidth capacity to the Asia-Pacific region, supporting the exponential growth in data demand driven by artificial intelligence (AI), the Internet of Things, and Cloud computing.
By offering a high-speed and resilient submarine communication network, the project not only enhances international telecommunications cooperation but also plays an essential role in fostering the high-quality development of the digital economy. In alignment with Hong Kong’s vision of becoming an International Innovation and Technology Hub, China Telecom Global is accelerating the development of major infrastructure projects, including the Tseung Kwan O Data Center, the Chung Hom Kok Cable Landing Station, and the New Eurasia and New Asia-Pacific submarine cables. The company is also strengthening its R&D capabilities through the establishment of AI and cybersecurity innovation centres, reinforcing its long-term commitment to driving technological progress and contributing to Hong Kong’s continued prosperity.
As the backbone of the global Internet, submarine cables serve as a vital lifeline for international data transmission. In the near future, China Telecom will collaborate with major global operators to continuously promote more submarine cable construction projects, further reinforcing the infrastructure that underpins 5G, AI, and digital technologies.
