Introduction
Subsea fibre-optic cables carry over 99% of international data traffic, connecting continents through light signals. They underpin digital transactions, communication and services, making their resilience essential for economic stability.
Significance
- Economic backbone: Facilitate banking, international payments, e-commerce and coordination of global supply chains.
- Digital transformation: Offer high bandwidth and low latency for cloud computing, artificial intelligence and research.
- India’s interests: Support IT exports, digital businesses and connectivity with global markets.
Technological challenges
- Engineering complexity: Deep-sea pressure, corrosion and signal attenuation require protective layers, repeaters and reliable power.
- Difficult repairs: Locating faults and deploying specialised vessels is expensive; weather and permissions delay restoration.
- Physical damage: Fishing nets, anchors, earthquakes and submarine landslides threaten cable integrity.
Security challenges
- Deliberate interference: Sabotage, espionage and cyberattacks on landing stations can disrupt communications.
- Strategic chokepoints: Concentration of routes and landing stations increases vulnerability to simultaneous failures.
- Governance gaps: Cross-border ownership and overlapping jurisdictions complicate surveillance, accountability and coordinated protection.
Conclusion
India must diversify cable routes, secure landing stations and strengthen domestic repair capacity. International cooperation and clear protection protocols can safeguard these digital lifelines while ensuring reliable and affordable connectivity.
