Tata Commits USD 450 Million for 10,000 km AI Fiber Network for Data Center

Tata Communications will invest between USD 400 million and USD 450 million in a dedicated fiber program intended to link India's major data-centre clusters into what the company calls an AI superhighway.

Announced on October 26, 2026, the build-out covers roughly 10,000 kilometers of new long-haul fiber and ranks among the largest AI-ready connectivity undertakings in the country.

The network will connect India's key AI data-center corridors with high-speed, low-latency capacity, and will be tied into the company's global backbone so customers receive an end-to-end fabric designed for the performance, resilience, and scale demanded by next-generation AI workloads. Planned users include global hyperscalers, AI platforms, neo-cloud providers, and enterprises, with deployment organized in three phases across India's highest-growth AI corridors.

Anchored by Contracted Demand, Says Management

Ganesh Lakshminarayanan, MD and CEO of Tata Communications, positioned the program against what he sees as a fast-forming domestic market for data-centre-to-data-centre connectivity. "We are excited about the opportunity in the India data centre-to-data centre connectivity, which we believe could evolve into a market exceeding USD 1 billion over the medium term," he said.

"With our planned investments, we are building on our existing strengths to create one of the most comprehensive data centre connectivity platforms in the market, positioning us to capture this significant growth opportunity." He also described the expansion as increasingly demand-led: a growing share of the company's build-out is driven by anchor customer commitments and contracted demand, which he said provides a strong foundation for sustainable growth, efficient capital deployment and long-term value creation.

Rupesh Chokshi, Chief Product and Technology Officer, Executive Vice President & Global Business Head, Network Services, argued that computing capacity on its own cannot sustain the AI economy. "The AI economy needs more than compute. It needs a network built for speed, scale and resilience," he said. "Our AI Network Fabric will give our global customers the ultra-low-latency, high-capacity and resilient connectivity they need to scale AI with confidence. By connecting India's AI and data center hubs to the world, we are enabling our customers to grow and helping fuel India's next chapter of economic growth."

First Phase Runs Mumbai to Chennai

Phase one will concentrate on the Mumbai-Pune-Hyderabad-Chennai corridor, which the company identifies as one of India's most significant AI and hyperscale growth routes. Later phases will push connectivity into emerging East Coast and Western India data-centre ecosystems, reaching Vizag, Bhubaneswar, Jamnagar, GIFT City and other strategic locations.

A central aim of the program is to link the key AI corridors and data-centre clusters to international cable landing stations, allowing seamless connectivity between India and major global AI hubs. The company says this positions India as a strategic gateway in the global digital infrastructure landscape. Alongside the new build, Tata Communications will keep serving existing enterprise and data-centre connectivity needs by scaling its current National Long Distance and metro network footprint, so present growth remains supported while capacity is added for future demand.

Connectivity Rises to Par with Compute and Power

The company's case for the investment rests on the trajectory of India's data-centre industry, which it expects to grow significantly in the near term on the back of accelerating cloud adoption, AI deployment, tightening data localisation requirements and rising enterprise demand for resilient, high-capacity digital infrastructure. As data-centre capacity expands rapidly across the country, Tata Communications contends that connectivity is becoming as critical as compute power and energy availability in enabling the next generation of digital services.

The investment is meant to reinforce India's emergence as a global AI and cloud connectivity gateway. Target demand comes from hyperscale and neocloud providers, AI workloads, digital-native businesses, Global Capability Centres (GCCs), enterprises and emerging cloud platforms. It is also intended to let global hyperscalers, digital platforms and multinational enterprises scale their India operations as the country moves into its next phase of digital transformation.

Layered Onto a 500,000 km Subsea Backbone

The AI super highway will run on top of Tata Communications' existing network fabric, which the company describes as the backbone of its portfolio. That backbone includes one of the largest wholly owned and most advanced subsea fiber networks underpinning the internet, spanning more than 500,000 kilometres of subsea optical fiber and more than 200,000 kilometres of terrestrial fiber.

The backbone itself has been under active international expansion. In June 2026, the company moved to strengthen its Tata Global Network (TGN) capabilities by planning a new subsea cable system between Mumbai and Singapore, and took an investment position as a consortium member in a new subsea cable system connecting Chennai to Singapore, with expected Ready for Service (RFS) in Q4 2029. Earlier, in 2025, the company integrated the TGN IA2 (Tata Global Network – Intra-Asia 2) submarine cable.

That integration delivered improved latency for faster performance, greater reliability through added redundancy, and increased network diversity via seamless interconnection with TGN IA. Tata Communications, part of the Tata Group and listed on the NSE (TATACOMM) and BSE (500483), operates as a global digital ecosystem enabler across more than 190 countries and territories.
