MODA Calls for Reinforced Undersea Cables

Why It Matters

Strengthening cable resilience safeguards Taiwan’s critical communications and supports its broader AI and digital infrastructure strategy, reducing economic and security risks.

Key Takeaways

• MODA urges deeper, steel‑jacketed undersea cables
• Anchor incidents cause most coastal cable disruptions
• Amendment allows confiscating vessels linked to sabotage
• Subsidies fund backup microwave links and early warnings
• Domestic projects Taiwan‑Matsu 4, Penghu‑Kinmen 4 finish 2026

Pulse Analysis

Undersea cables form the backbone of global data traffic, yet they remain vulnerable to both accidental damage—often from ship anchors—and deliberate sabotage. Recent incidents worldwide have highlighted how a single cut can disrupt internet services for millions, prompting governments to reassess protection strategies. Taiwan, situated at a strategic crossroads of East Asian data routes, faces heightened exposure, making MODA’s call for deeper burial and steel jacketing a critical step toward mitigating these risks.

MODA’s response blends regulatory and financial tools. By amending Article 72 of the Telecommunications Management Act, authorities can now seize vessels proven to have caused sabotage, creating a deterrent against malicious acts. Simultaneously, the ministry is expanding subsidy programs to fund backup microwave links, early‑warning systems, and rapid‑repair capabilities, ensuring continuity even if a cable is compromised. Encouraging participation in regional systems such as Southeast Asia‑Japan 2 and Apricot further diversifies routing options, reducing reliance on any single conduit.

For telecom operators and investors, these measures signal a shift toward layered resilience and open market opportunities. Enhanced protection standards may increase upfront infrastructure costs, but they also lower long‑term outage risk, protecting revenue streams and national security interests. The accelerated rollout of domestic projects—Taiwan‑Matsu No. 4, Taiwan‑Penghu No. 4, and Penghu‑Kinmen No. 4—positions Taiwan as a more reliable hub in the Pacific data corridor, potentially attracting new partnerships and reinforcing its role in the region’s digital economy.
