Tata Communications, a global communications technology leader, announced strategic investments in subsea cable infrastructure to strengthen connectivity between Mumbai and Chennai in India and Singapore, Asia's leading cloud and AI ecosystem. The investments, announced on July 6, 2026, aim to address growing bandwidth and AI-driven data demands for enterprises across Asia and globally.
Investment Details
The company is enhancing its Tata Global Network (TGN) capabilities by integrating a new subsea cable system between Mumbai and Singapore, and investing as a consortium member in a new cable system connecting Chennai to Singapore, with expected Ready for Service (RFS) in Q4 2029. These investments will significantly increase capacity on the India-Singapore route, which is projected to become one of the world's most critical digital corridors.
Strategic Importance
The India-Singapore subsea route is set to underpin critical enterprise, cloud, and hyperscaler traffic between India, Southeast Asia, and global markets. By enhancing TGN network capacity, Tata Communications aims to deliver diverse, agile, and high-performance connectivity to customers, meeting the growing needs of the Data Centre (DC) ecosystem.
“As global demand for digital and AI-driven services continues to accelerate, these investments reinforce our commitment to building future-ready digital infrastructure at scale,” said Genius Wong, Executive Vice President – Core and Next-Gen Connectivity Services, and Chief Technology Officer, Tata Communications. “By combining subsea capacity enhancement with both short term and long-term strategic investments, we are strengthening the reliability, scalability and performance of connectivity solutions for our customers across one of the world’s busiest digital corridors.”
Network Integration
The new cable systems will connect with Tata Communications' India terrestrial fiber network for seamless onward connectivity to other parts of the country and to over 100 Data Centres nationwide. Combined with the global TGN subsea network, this will enhance the full suite of IZO™ connectivity solutions, including IZO™ DC Dynamic Connectivity and IZO™ Multi-cloud connectivity solutions, providing self-healing, always-on, and self-provisioning capabilities across DCs and cloud ecosystems.
Tata Communications' network fabric remains the backbone of its portfolio, operating the largest wholly-owned and most advanced subsea fiber network, spanning over 500,000 km of subsea optical fiber and 200,000 km of terrestrial fiber. In 2025, the company integrated the new TGN IA2 submarine cable, improving latency, enhancing reliability through greater redundancy, and increasing network diversity.
