Tata Communications strengthens India-Singapore digital corridor

- Strengthened connectivity between Mumbai and Singapore as well as Chennai and Singapore

- Resulting network will be seamless and self-healing, from subsea to terrestrial

- Cable systems will connect directly to Tata Communications' terrestrial fibre network

Tata Communications, a global communications technology player, has announced investments in subsea cable infrastructure via the acquisition of significant fibre capacity that will strengthen its connectivity solutions between the emerging AI hubs of Mumbai and Chennai in India and Singapore, Asia’s leading cloud and AI ecosystem. 

The company is enhancing its Tata Global Network (TGN) capabilities by integrating a new subsea cable system between Mumbai and Singapore, and also investing as a consortium member in a new subsea cable system that connects Chennai to Singapore. The new system is expected to be ready for service (RFS) in Q429. Both investments are aimed at addressing the growing bandwidth and AI-driven data demands of enterprises across Asia and further extension globally.

The India-Singapore subsea route is set to become one of the world’s most critical digital corridors in future, representing a high-capacity, low-latency pathway that will underpin critical enterprise, cloud, and hyperscaler traffic between India, Southeast Asia, and global markets. By enhancing capacity on its TGN network, Tata Communications is furthering its ability to deliver diverse, agile and high-performance connectivity to customers. 

“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 VP – Core and Next-Gen Connectivity Services, and CTO, 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. 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 cable systems will further connect with the Tata Communications India Terrestrial fibre network for seamless onward connectivity to other parts of the country and to 100+ data centres (DCs) nationwide. Combined with the Tata Communications Global TGN Subsea network, the new capabilities are expected to enhance IZO connectivity solutions such as IZO DC Dynamic Connectivity and IZO Multi-cloud connectivity solutions. The IZO family provides self-healing, always-on and self-provisioning capabilities across DCs and cloud ecosystems. 

Tata Communications' Network Fabric remains the backbone of its portfolio, operating the largest wholly-owned and most advanced subsea fibre network which underpins the Internet backbone, spanning 500,000+ km of subsea optical fibre and 200,000+ km of terrestrial fibre. In 2025, Tata Communications integrated the new TGN IA2 (Tata Global Network – Intra-Asia 2) submarine cable into its network fabric, achieving faster performance, enhanced reliability through greater redundancy, and increased network diversity through seamless interconnection with the TGN IA cable.
