What's Happening?
China Mobile has announced the commercial operation of the Southeast Asia-Hainan-Hong Kong (SEA-H2X) submarine cable system, a 5,746-kilometer network connecting Hong Kong and Singapore with links to Hainan, China, Songkhla, Thailand, and La Union, Philippines.
This development follows a two-year delay due to adverse weather and permit issues. The SEA-H2X system, featuring eight fiber pairs with a capacity exceeding 200 Tbit/s, aims to improve communication infrastructure in Greater China and the Asia-Pacific region. Additionally, the Sihanoukville-Hong Kong (SHV-HK) cable, Cambodia's first state-owned submarine optical fiber system, has reached Hong Kong, enhancing Cambodia's digital connectivity.
Why It's Important?
The launch of the SEA-H2X cable is significant for the digital infrastructure in Asia, addressing the growing demand for bandwidth driven by AI workloads. It strengthens the digital backbone between China and Southeast Asia, facilitating low-latency communication and expanding cross-border cloud routing. This development is crucial for economic growth in the region, as it supports the digital economy and enhances connectivity. The SHV-HK cable further integrates Cambodia into the global digital network, promoting economic development and regional cooperation.
What's Next?
China Mobile plans to integrate the SEA-H2X cable with existing Asia-Pacific submarine systems and connect them to its global terrestrial network. This integration aims to establish a cross-continental transmission corridor spanning the Asia-Pacific, Middle East, and Europe. The SHV-HK system is expected to enhance Cambodia's digital connectivity, supporting the China-Cambodia partnership and contributing to the Digital Silk Road initiative.
