Undersea Cables

Undersea Cables: Critical Infrastructure for Digital Growth

The undersea cable network, connecting global internet systems, represents a vital backbone for international connectivity, digital economies, and even geopolitical influence. India’s recent initiatives, including the landing of 2Africa Pearls and SEA-ME-WE-6 (SMW6), highlight its drive to elevate its digital infrastructure. This development operates within the conceptual framework of "critical infrastructure resilience vs strategic vulnerability". With over 90% of global data flowing through these systems, their strategic and technological significance is unmatched. However, risks like disruptions, regulatory hurdles, and repair delays demand careful evaluation to ensure India’s readiness.

Conceptual Clarities for Answer-Writing

1. Undersea Cables as Critical Infrastructure

Undersea cables are fiber-optic networks laid across oceans to facilitate internet, data exchange, and communication globally. They account for 90% of international data traffic and are critical for services ranging from financial transactions to basic email exchanges. These systems represent the intersection of technological efficacy and geopolitical vulnerability, given their exposure to disruptions.

• Fiber Optic Functionality: Based on Total Internal Reflection (TIR), light pulses travel through the core with minimal loss.
• Resilience Measures: Cables are heavily padded and laid at depths of up to 7,000 meters.
• Global Consortia: SMW6 includes telecom actors spanning Europe, Middle East, and Asia.
• Data Handling Capacity: Meta’s Project Waterworth aims at over 50,000 km of subsea cables to support AI-driven data processing.
• Exam Trap: Confusing undersea cables with satellite internet systems.

2. India’s Strategic Position

With hubs in Chennai and Mumbai, India hosts 17 cable systems, making it a key player in regional connectivity. Projects like CANI (Chennai-Andaman & Nicobar Islands) and Kochi-Lakshadweep broaden domestic digital inclusion, while recent international systems like 2Africa Pearls highlight future readiness.

• Global Connectivity Impact: SEA-ME-WE-6 runs 21,700 km, linking Singapore to France via India.
• Domestic Benefits: Better bandwidth supports India’s ambition for a $1 trillion digital economy.
• Geopolitical Leverage: Enhanced international partnerships through consortia.
• Exam Trap: Underestimating their economic and security role compared to terrestrial fiber optics.

Evidence and Data

India's critical reliance on undersea cables can be validated by authoritative sources such as NITI Aayog reports and global exemplars. While India continues to expand its cable footprint, risks persist in operational delays, geographical dependencies, and high repair timelines.

Limitations and Open Questions

While India has made strides in submarine cable connectivity, several critical limitations hinder its operational and strategic potential:

• Repair Challenges: India lacks local vessels for cable maintenance, leading to costly delays.
• Geopolitical Risks: High dependency on international consortia (e.g., SMW6), raising concerns during global tensions.
• Regulatory Complexity: Excessive clearances limit deployment speed.
• Future Data Demand: NFHS digital usage trends suggest significant growth; infrastructure robustness must match.
• Unresolved Question: Should India prioritize private or public ownership models for subsea cable systems?

Structured Assessment

• Policy Design: Clear categorization of cables as critical telecom infrastructure could ensure robust policy incentives, including tax exemptions.
• Governance Capacity: Streamlining regulatory approvals and investing in local repair capabilities should be immediate priorities.
• Behavioural/Structural Factors: Aligning fishermen activities through cable corridors and raising local awareness about their importance can reduce accidental damage.

Way Forward

To enhance India's undersea cable infrastructure and ensure its strategic advantage, several actionable policy recommendations should be considered. First, the government should prioritize investment in local repair capabilities to reduce dependency on foreign vessels and expedite maintenance processes. Second, establishing a dedicated regulatory framework that simplifies the approval process for new cable projects can accelerate deployment. Third, fostering partnerships with private sector players can drive innovation and efficiency in cable laying and maintenance. Fourth, promoting awareness and education about the importance of undersea cables among local communities can mitigate risks of accidental damage. Lastly, India should explore diversifying its cable routes to minimize geopolitical risks associated with reliance on specific international consortia.
