China Telecom Advances ALC Landing in Hong Kong

Why It Matters

The ALC dramatically expands regional data throughput, positioning China Telecom as a key backbone provider for cloud, AI and low‑latency services across Asia, while strengthening China’s strategic digital infrastructure.

Key Takeaways

• ALC spans 6,200 km, linking six Asian economies
• Designed capacity exceeds 325 Tb/s, boosting regional bandwidth
• China Telecom gains over 100 Tb/s additional capacity
• First China Telecom submarine landing in Hainan, filling connectivity gaps
• Supports Greater Bay Area, Belt and Road digital infrastructure

Pulse Analysis

Submarine cables remain the silent workhorses of the global internet, and the Asia Link Cable (ALC) is a textbook example of next‑generation infrastructure. Stretching roughly 6,200 kilometres across the South China Sea, the system connects Hong Kong, Hainan, Singapore, the Philippines, Vietnam, Brunei and Malaysia. Its design capacity of more than 325 terabits per second eclipses existing routes, offering the low‑latency pathways essential for data‑intensive applications such as cloud computing, artificial intelligence models and real‑time financial trading. By landing at the Chung Hom Kok station, the ALC also diversifies Hong Kong’s cable landing portfolio, reducing reliance on older fibers and enhancing network resilience.

For China Telecom, the ALC is a strategic lever that expands its international backbone by over 100 Tb/s, directly translating into higher traffic handling capability and more competitive service offerings. The partnership with 13 other operators underscores a collaborative approach to regional connectivity, yet China Telecom’s role as the primary investor and manager cements its leadership position in the Asia‑Pacific telecom landscape. This capacity boost enables the carrier to capture a larger share of burgeoning demand for high‑bandwidth services, from hyperscale cloud providers to emerging 5G and future 6G ecosystems, while also improving traffic routing efficiency across its existing network.

Beyond corporate gains, the cable aligns with broader economic initiatives. The Greater Bay Area and Belt‑and‑Road strategies rely heavily on robust digital links to facilitate trade, innovation and cross‑border data flows. By providing a high‑capacity conduit between key Asian markets, the ALC supports Hong Kong’s ambition to evolve into an international innovation hub and helps Hainan close its international connectivity gap. In a region where data traffic is projected to double within the next five years, the ALC positions its stakeholders to meet that surge, fostering a more integrated and digitally resilient Asia.
