Tata Communications Invests in Subsea Cables to Boost AI-Ready Connectivity Between India and Singapore
Tata Communications, a global communications technology provider, has announced strategic investments in subsea cable infrastructure through significant fiber capacity acquisitions. These moves are designed to strengthen connectivity solutions between the emerging Artificial Intelligence (AI) hubs of Mumbai and Chennai in India and the leading cloud and AI ecosystem in Singapore, addressing growing bandwidth demands across Asia and globally.The company is enhancing its Tata Global Network (TGN) capabilities by two key initiatives: integrating a new subsea cable system connecting Mumbai and Singapore, and investing as a consortium member in a new subsea cable that will link Chennai to Singapore, with an expected Ready for Service (RFS) date set for Q4 2029.
This planned India-Singapore subsea route is poised to become one of the world's critical digital corridors, providing a high capacity, low latency pathway essential for enterprise, cloud, and hyperscaler traffic between global markets, Southeast Asia, and India. These combined investments aim to meet the escalating needs of the Data Centre (DC) ecosystem by offering scalable and reliable connectivity between the two key hubs.
Genius Wong, Executive Vice President - Core and Next-Gen Connectivity Services, and Chief Technology Officer at Tata Communications, commented on the developments. He stated that these investments reinforce the company's commitment to building future-ready digital infrastructure. "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," Wong said. He added that these enhancements align with Tata Communications' strategy to expand its global subsea network footprint and reinforce India's position as a Digital Hub.
These new cable systems will integrate seamlessly with Tata Communications India Terrestrial fiber network, providing onward connectivity to 100+ Data Centres (DCs) across the country. Combined with the Global TGN Subsea network, these additions enhance services such as IZO TM DC Dynamic Connectivity and IZO TM Multi-cloud connectivity solutions, offering customers self-healing, always-on, and self-provisioning capabilities integrated into their networks on demand.
Tata Communications Network Fabric operates the largest wholly owned and most advanced subsea fiber network, spanning 500,000+ km of subsea optical fiber and 200,000+ km of terrestrial fiber, forming the backbone of its portfolio. The company also highlighted that in 2025, it integrated the new TGN IA2 (Tata Global Network - Intra-Asia 2) submarine cable, which improved latency and enhanced reliability across this corridor.
