Tata Communications announced strategic investments in subsea cable infrastructure to strengthen connectivity between the emerging AI hubs of Mumbai and Chennai in India and Singapore. These investments aim to address the growing bandwidth and AI-driven data demands of enterprises across Asia and globally by enhancing the Tata Global Network (TGN) capabilities. The India-Singapore subsea route is set to become a critical digital corridor, providing a high-capacity, low-latency pathway for enterprise, cloud, and hyperscaler traffic.

Strategic Capacity Enhancements

The company is enhancing its network through two primary initiatives involving significant fiber capacity acquisition. The first involves integrating a new subsea cable system between Mumbai and Singapore, while the second entails an investment as a consortium member in a new system connecting Chennai to Singapore with an expected Ready for Service (RFS) in Q4 2029. These additions are designed to create a high-capacity, low-latency pathway critical for real-time and AI-driven workloads. In 2025, the company integrated the TGN IA2 submarine cable to improve latency and reliability.

Network Infrastructure and Capabilities

The new cable systems will connect with Tata Communications' India terrestrial fiber network, providing seamless onward connectivity to other parts of the country and over 100 Data Centres nationwide. This integration enhances the company's IZO™ connectivity solutions, offering self-healing and self-provisioning capabilities across data centre and cloud ecosystems. The network currently spans over 500,000 km of subsea optical fiber and 200,000 km of terrestrial fiber.

Future Outlook

Genius Wong, Executive Vice President – Core and Next-Gen Connectivity Services, and Chief Technology Officer, stated that these investments reinforce the commitment to building future-ready digital infrastructure. The enhancements align with the long-term strategy to expand the global subsea network footprint and reinforce India's position as a digital hub, meeting the needs of the data centre ecosystem with scalable and reliable connectivity.
