Tata Communications Invests $152 Million in Subsea Cables to Boost India-Singapore AI Corridor
India’s Tata Communications has announced a strategic investment of $152 million in subsea cable infrastructure aimed at expanding the digital corridor between India and Singapore. The investment will add 98 terabits per second of AI-ready capacity to the route, which the company says is becoming one of the world’s most critical digital arteries.
In a statement released on Tuesday, Tata Communications emphasized that the investment addresses the surging demand for bandwidth and AI-driven data across Asia and globally. The India-Singapore subsea route currently handles more than 35 percent of global internet traffic that passes through Tata Communications’ on-net global network, underscoring its strategic importance. The new capacity is designed to improve network diversity, resilience, and low-latency connectivity to support enterprise, cloud, and hyperscaler traffic, which are driving Asia’s digital economy, AI adoption, cloud computing, and data-intensive applications.
The investment includes integrating a new subsea cable system between Mumbai and Singapore, as well as participating as a consortium member in another new cable system connecting Chennai to Singapore. Both cable systems are expected to be ready for service in the fourth quarter of 2029. Once operational, these systems will link with Tata Communications’ terrestrial fiber network in India, providing onward connectivity to more than 100 data centers nationwide. Combined with the company’s global TGN subsea network, the investment will enhance its IZO connectivity solutions, including IZO DC Dynamic Connectivity and IZO Multi-cloud Connectivity, which offer self-healing, always-on, and self-provisioning capabilities across data center and cloud ecosystems.
Genius Wong, Executive Vice President of Core and Next-Gen Connectivity Services and Chief Technology Officer at Tata Communications, said the investments reinforce the company’s commitment to building future-ready digital infrastructure at scale. “This strengthens the reliability, scalability, and performance of connectivity solutions across one of the world’s busiest digital corridors, while reinforcing India’s position as a digital hub,” Wong added.
The move highlights the growing importance of subsea cable infrastructure in supporting the rapid expansion of AI and cloud computing in the Asia-Pacific region. As data centers face mounting energy and connectivity challenges, investments like this are critical to ensuring that the region’s digital economy can scale sustainably. Tata Communications’ latest commitment signals a long-term bet on India’s role as a central node in global data flows, particularly as AI workloads become more data-intensive and geographically distributed.
