Strengthening India-Singapore digital corridor: Boost to its subsea digital presence

Tata Communications (TCL), a leading global communications technology player, has announced strategic investments in subsea cable infrastructure via acquisition of significant fiber capacity to strengthen its connectivity solutions between the emerging AI hubs of Mumbai & Chennai in India and Singapore, Asia’s leading cloud and AI ecosystem. These investments are aimed at addressing the growing bandwidth and AI-driven data demands of enterprises across Asia and globally.

The company is enhancing its Tata Global Network (TGN) capabilities by integrating a new subsea cable system between Mumbai and Singapore and by investing as a consortium member in a new subsea cable system connecting Chennai to Singapore, expected to be ready for service in Q4FY29. The investment involved has not been specified.

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, the company 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 (DC) ecosystem, offering enterprises a scalable, reliable and future-ready connectivity between India and Singapore.

MEETING DEMAND

“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 CTO.

She 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. These enhancements align with our 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.”

These cable systems will further connect with TCL’s India Terrestrial fiber network for seamless onward connectivity to other parts of the country and to 100+ Data Centres (DCs) nationwide. Combined with the company’s global TGN subsea network, this will enhance the capabilities of the full suite of IZO™ connectivity solutions such as IZO™ DC Dynamic Connectivity and IZO™ multi-cloud connectivity solutions, providing self-healing, always-on and self-provisioning capabilities across DCs and clouds ecosystems. Customers will be able to activate and integrate these capacities with agility into their networks on demand.

TCL’s 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 500,000+ km of subsea optical fiber and 200,000+ km of terrestrial fiber.

IMPROVED NETWORK

In a significant step forward for enterprise connectivity across Asia and beyond, in 2025 the company 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.

A part of the Tata group, TCL is a global digital ecosystem enabler powering today’s fast-growing digital economy in more than 190 countries and territories. It enables digital transformation of enterprises globally with collaboration and connected solutions, core and next-gen connectivity, cloud hosting, and security solutions and media services. 300 of the Fortune 500 companies are its customers and the company connects businesses to 80% of the world’s cloud giants.
