Global communications technology firm Tata Communications has announced that it will be investing US$ 152 million in its subsea cable infrastructure connecting Mumbai and Chennai to Singapore in a bid to strengthen the connectivity between India’s emerging AI hubs.
Tata Communications states in a press release that this subsea cable route will deliver high-capacity, low-latency connectivity for critical cloud, enterprise and hyperscaler traffic between India, Southeast Asia, and the world at large.
“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.”
Diving into the specifics of these subsea cable systems, a new solution will be deployed between Mumbai and Singapore, but at this stage there is no timeline on when this will be completed or ready for service. To connect Chennai to Singapore, Tata Communications will invest in a new subsea cable system as a consortium member, with the cable expected to be ready for service in Q4 2029.
These projects will complement the Tata Global Network – Intra-Asia 2 (TGN-IA2) which the company launched in 2025. Built by a consortium, Tata Communications owns half of the eight fiber pairs in this cable system, which is a sub-system of the Asia Direct Cable. The system features a capacity of 20 Tbps per fiber pair and connects Singapore, Hong Kong, China, Thailand, Philippines, and Japan.
Once these cable systems are ready for service, they will facilitate connectivity to Tata Communications’ terrestrial fiber network, which provides connections to more than 100 data centres across India.
This connectivity has become vital in India where AI use has exploded with the AI data center market se to grow at a CAGR of 21.08 percent according to Mordor Intelligence. With that explosion a need for dedicated, low-latency, high-capacity connectivity has emerged, and Tata Communications is capitalizing on that need.
