Tata Communications announces investments to expand subsea cable capacity on India–Singapore routes, aiming to support growing enterprise, cloud and AI traffic between the two countries. The company says it will strengthen its Tata Global Network (TGN) by integrating a new subsea cable system between Mumbai and Singapore. In addition, Tata Communications plans to invest as a consortium member in another subsea cable project connecting Chennai to Singapore, which is expected to be ready for service by Q4 2029. Business Standard reports the expansion adds about 98 terabits per second (Tbps) of capacity through the two cable projects, and it says the investment is $152 million. Other reports focus on the intent to build a higher-capacity, low-latency digital corridor and to integrate the subsea systems with Tata Communications’ terrestrial fiber network for onward connectivity across India. The company also frames the move as part of meeting rising bandwidth demand from India’s data centre ecosystem and AI-related workloads. The plans align with broader industry momentum, with Microsoft and other firms also discussing submarine cable build-outs across India and Southeast Asia for cloud and AI growth by 2029.

1 month agoTata Communications on Tuesday announced strategic invetsments in subsea cable infrastructure between India and Singapore through acquisition of significant fiber capacity, to strengthen its connectivity solutions between the emerging AI hubs of the two countries.The company is enhancing its Tata Global Network (TGN) capabilities by integrating a new subsea cable system between Mumbai & Singapore and investing as a consortium member in a new subsea cable system, connecting Chennai to Singapore which is expected to be ready for service by Q4 2029.However, Tata Communications did not reveal the exact sum of investment into the project.The strategic investments come at a time when India's data centre market is projected to reach US$ 13.11 billion (Rs. 108,813 crore) by 2034, growing at a CAGR of 10.01% during 2026–2034, according to IBEF. The subsea cable systems connect continents, and their data centre clusters, serving as the lifeline for inter-regional workloads. With the ongoing boom in India's data centre market, the need for subsea cables is fast rising. "These investments will meet the growing needs of the Data Centre (DC) ecosystem offering enterprises a scalable, reliable & future ready connectivity between India and Singapore," the company said.Tata's subsea cable 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, the company said, 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.The cable systems will 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 operates 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 2025, Tata Communications integrated the TGN IA2 (Tata Global Network – Intra-Asia 2) submarine cable, improving latency for faster performance, increasing network diversity through seamless interconnection with TGN IA.Earlier in February, Google announced 'America-India Connect' to establish a new international subsea gateway in Visakhapatnam (Vizag), three new subsea paths connecting India to Singapore, South Africa, and Australia, and four strategic fiber-optic routes to bolster network resilience and capacity between the United States, India, and multiple locations across the Southern Hemisphere.The project is a part of its five-year $15 billion AI infrastructure investment in India to increase the reach, reliability, and resilience of digital connectivity across four continents.
