Tata Communications is investing in new subsea cable infrastructure between Mumbai, Chennai, and Singapore, adding 98 Tbps of AI-ready network capacity. The investment strengthens one of the world's most critical digital corridors, supporting growing enterprise, hyperscaler, and data centre traffic between India and Southeast Asia.
Tata Communications has announced strategic investments in subsea cable infrastructure to strengthen connectivity between the emerging AI hubs of Mumbai and Chennai in India and Singapore, Asia's leading cloud and AI ecosystem. The investment includes integrating a new subsea cable system between Mumbai and Singapore, and investing as a consortium member in another cable system connecting Chennai to Singapore with expected readiness in Q4 2029.
The investment will add 98 Tbps of AI-ready network capacity across the India-Singapore digital corridor. The India-Singapore subsea route is projected to become one of the world's most critical digital corridors, representing a high-capacity, low-latency pathway that will underpin enterprise, cloud, and hyperscaler traffic between India, Southeast Asia, and global markets. The enhancements align with Tata Communications' strategy to expand its global subsea network footprint, which already spans over 500,000 km of subsea optical fibre.
These cable systems will connect with Tata Communications' India terrestrial fibre network for seamless onward connectivity to 100+ data centres nationwide. Combined with the company's global TGN subsea network, the investment will enhance the capabilities of its IZO connectivity solutions, providing self-healing, always-on, and self-provisioning capabilities across data centre and cloud ecosystems. Customers will be able to activate and integrate these capacities on demand.
The announcement follows Tata Communications' integration of the TGN IA2 submarine cable in 2025, which improved latency and enhanced reliability across the Asia region. The company stated that the investment addresses the growing bandwidth and AI-driven data demands of enterprises across Asia and beyond, and reinforces India's position as a digital hub.
Why it matters for Singapore: Singapore's position as Southeast Asia's premier cloud and AI hub depends on robust international connectivity. The Tata Communications investment directly strengthens the subsea cable capacity linking Singapore to India's tech ecosystem, ensuring that the data centre and AI infrastructure being built in Singapore has the bandwidth to serve the region. As AI workloads become more data-intensive, this kind of infrastructure investment is critical to maintaining Singapore's competitiveness as a regional digital hub.
