Tata Communications is investing in subsea cable capacity to strengthen the digital corridor between Mumbai, Chennai and Singapore, to meet rising enterprise demand for bandwidth and AI-driven data traffic across Asia.
The upgrades will improve speed, reliability and low-latency connectivity for cloud, data centre and hyperscaler workloads.
The commitments include adding capacity on a new Mumbai-Singapore cable system and a consortium investment in a Chennai-Singapore cable expected to be ready for service in Q4 2029. The route is set to become one of the world’s most critical digital corridors linking India, Southeast Asia and global markets with a high-capacity pathway for enterprise traffic.
For enterprises in Southeast Asia, the significance is practical and strategic. Faster, more resilient links to India can support AI applications, cloud migration, real-time collaboration and data-heavy workloads that depend on stable cross-border connectivity.
The increased capacity will also connect into its terrestrial network and more than 100 data centres in India to help customers extend networks across clouds and data centres with self-provisioning and always-on capabilities.
Part of a broader regional push, the enhanced infrastructure will support the company’s Tata Global Network and strengthen its ability to serve digital businesses operating across Asia.
Tata Communications operates a global subsea and terrestrial network spanning more than 500,000 km of subsea fibre and 200,000 km of terrestrial fibre.
“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, who added, “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.”
