India – Tata Communications has announced strategic investments in subsea cable infrastructure, acquiring significant fiber capacity to strengthen connectivity between the emerging AI hubs of Mumbai and Chennai in India and Singapore, a major regional cloud and AI hub.
The investments aim to address rising demand for bandwidth and AI-driven data workloads among enterprises across Asia while supporting international connectivity.
As part of the initiative, Tata Communications will integrate a new subsea cable system between Mumbai and Singapore and invest as a consortium member in another subsea cable linking Chennai and Singapore, which is expected to be ready for service in the fourth quarter of 2029.
The expanded infrastructure is intended to increase capacity along the India–Singapore subsea route, supporting enterprise, cloud, and hyperscaler traffic between India, Southeast Asia, and global markets. The additional capacity will also strengthen the company’s Tata Global Network (TGN) and support growing demand from the region’s data centre ecosystem with improved connectivity between India and Singapore.
The new cable systems will connect with Tata Communications’ terrestrial fibre network in India, extending connectivity to more than 100 data centres nationwide. The expanded infrastructure will also support the company’s IZO connectivity portfolio, including data centre and multi-cloud networking services, enabling enterprises to provision and manage network capacity on demand across data centre and cloud environments.
Tata Communications said its global network currently spans more than 500,000 kilometres of subsea optical fibre and over 200,000 kilometres of terrestrial fibre, forming the foundation of its enterprise connectivity services.
“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.
Wong continued, “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. These enhancements align with Tata Communications’ long-term strategy to expand its global subsea network footprint, provide business outcome solutions to customers and reinforce India’s position as a Digital Hub.”
The latest investments build on the company’s network expansion efforts. In 2025, Tata Communications integrated the Tata Global Network – Intra-Asia 2 (TGN IA2) submarine cable into its network to improve latency, increase redundancy, and expand network diversity across Asia.
