Tata Communications, a leading global communications technology player, announced strategic investments in subsea cable infrastructure via acquisition of significant fiber capacity, to strengthen its connectivity solutions between the emerging AI hubs of Mumbai and Chennai in India and Singapore, Asia’s leading cloud and AI ecosystem. These investments are aimed at addressing the growing bandwidth and AI-driven data demands of enterprises across Asia and further extension globally.
Tata Communications is enhancing its Tata Global Network (TGN) capabilities by:
- Integrating a new subsea cable system between Mumbai & Singapore
- Investing as a consortium member in a new subsea cable system, connecting Chennai to Singapore with expected Ready for Service (RFS) in Q4 2029
The India-Singapore subsea route is set to become one of the world’s most critical digital corridors in future, representing a high-capacity, low-latency pathway that will underpin critical enterprise, cloud, and hyperscaler traffic between India, Southeast Asia, and global markets. By enhancing capacity on its TGN network, Tata Communications is furthering its ability to deliver diverse, agile and high-performance connectivity to customers. Together, these investments will meet the growing needs of the Data Centre (DC) ecosystem offering enterprises a scalable, reliable & future ready connectivity between India and Singapore.
“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 Ms. 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. 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.”
These cable systems will further connect with Tata Communications India Terrestrial fiber network for seamless onward connectivity to other parts of the country and to 100+ Data Centres (DCs) nationwide. Combined with Tata Communications Global TGN Subsea network, this shall enhance the capabilities of the full suite of IZOTM connectivity solutions such as IZOTM DC Dynamic Connectivity and IZOTM Multi-cloud connectivity solutions providing self-healing, always-on and self-provisioning capabilities across DCs and Clouds ecosystems. Customers will be able to activate and integrate these capacities with agility into their networks on demand.
Tata Communications Network Fabric remains the backbone of its portfolio, operating the largest wholly-owned and most advanced subsea fiber network which underpins the internet backbone, spanning 500,000+ km of subsea optical fiber and 200,000+ km of terrestrial fiber.
In a significant step forward for enterprise connectivity across Asia and beyond, in 2025, Tata Communications integrated the new TGN IA2 (Tata Global Network – Intra-Asia 2) submarine cable, improving latency for faster performance, enhancing reliability through greater redundancy and increasing network diversity through seamless interconnection with TGN IA.
