Tata Communications is investing in subsea cable infrastructure via acquisition of significant fiber capacity, to strengthen its connectivity solutions between the emerging AI hubs of Mumbai and Chennai in India and Singapore.
These investments are aimed at addressing the growing bandwidth and AI-driven data demands of enterprises across Asia and further extension globally.
Tata Communications is enhancing its Tata Global Network (TGN) capabilities by integrating a new subsea cable system between Mumbai and Singapore. It is also investing as a consortium member in a new subsea cable system, which will connect Chennai to Singapore with expected Ready for Service (RFS) in the fourth quarter of 2029.
The India-Singapore subsea route is expected to become one of the world’s most critical digital corridors, 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. Together, these investments will meet the growing needs of the data centre ecosystem offering enterprises a scalable, reliable & future ready connectivity between India and Singapore.
“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,” said Genius Wong, EVP and CTO of Tata Communications.
“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,” said Wong.
These cable systems will further connect with Tata Communications India Terrestrial fiber network for seamless onward connectivity to other parts of the country and to more than 100 data centres nationwide.
Tata Communications Network Fabric remains the backbone of its portfolio, operating the largest wholly-owned and most advanced subsea fiber network which underpins the internet backbone, spanning more than 500,000 km of subsea optical fiber and more than 200,000 km of terrestrial fiber.
In a significant step forward for enterprise connectivity across Asia and beyond, in 2025, Tata Communications integrated the new TGN IA2 (Tata Global Network – Intra-Asia 2) submarine cable, improving latency for faster performance, enhancing reliability through greater redundancy and increasing network diversity through seamless interconnection with TGN IA.
