Tata Communications has unveiled plans to invest $152 million in expanding its subsea cable network to strengthen connectivity between Mumbai and Chennai with Singapore.
The investment aims to improve digital links between India’s fast-growing artificial intelligence (AI) ecosystem and Southeast Asia. The company said the new subsea infrastructure will deliver high-bandwidth, low-latency connectivity for cloud platforms, enterprises, and hyperscale providers, enabling faster and more reliable digital services.
Commenting on the development, Genius Wong, Executive Vice President – Core and Next-Gen Connectivity Services and Chief Technology Officer at Tata Communications, said the company remains focused on developing large-scale digital infrastructure capable of supporting the rapidly increasing demand for AI-powered and digital services.
As part of the initiative, Tata Communications will deploy a new subsea cable connecting Mumbai and Singapore, although it has not disclosed the project completion schedule. The company will also join a consortium developing another subsea cable between Chennai and Singapore, which is scheduled to enter service by the fourth quarter of 2029.
These new systems will build upon the Tata Global Network – Intra-Asia 2 (TGN-IA2), introduced in 2025, which connects several Asian markets with a transmission capacity of 20 terabits per second per fibre pair.
After completion, the subsea infrastructure will be integrated with Tata Communications’ nationwide terrestrial fibre network, linking more than 100 data centres across India. The expansion comes as India’s AI data centre industry is expected to grow at a 21.08% compound annual growth rate (CAGR), according to Mordor Intelligence, driving increasing demand for high-capacity, low-latency connectivity to support AI workloads. Tata Communications expects its upgraded network to address these growing infrastructure requirements.
