Tata Communications says it will invest US$152 million to expand subsea cable capacity between India and Singapore, citing rising demand tied to AI workloads and the regional data centre ecosystem.
In material distributed to media on Tuesday, the company said the investment will add 98 terabits per second (Tbps) of capacity on the India–Singapore corridor and is intended to improve network diversity, resilience and low-latency connectivity for enterprise, cloud and hyperscaler traffic.
The plan includes integrating a new subsea cable system between Mumbai and Singapore and investing as a consortium member in a separate cable system connecting Chennai to Singapore, expected to be ready for service in Q4 2029.
Tata Communications said the new cable capacity will connect into its terrestrial fibre network in India to provide onward connectivity to more than 100 data centres nationwide.
Genius Wong, executive vice president for core and next-generation connectivity services and chief technology officer at Tata Communications, said: “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. 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 announcement comes amid continued growth in cross-border data flows and increased attention on cable route diversity and resilience for Asia-Pacific connectivity, particularly as more compute and storage capacity is added in regional data centre hubs.
