India's Tata Communications invests in new submarine cables to enhance India-Singapore connectivity, expected to be operational by 2029

en.Wedoany.com Reported - Global leading communications technology company Tata Communications announced a strategic investment in submarine cable infrastructure by acquiring substantial fiber capacity to strengthen connectivity solutions between Mumbai and Chennai in India and Singapore. As a leading cloud and AI ecosystem in Asia, Singapore is the focus of this investment, aimed at meeting the growing bandwidth and AI-driven data demands of Asian enterprises, with further expansion to global markets.

Tata Communications is enhancing its Tata Global Network (TGN) capabilities by integrating a new submarine cable system between Mumbai and Singapore, and by investing as a consortium member in a new submarine cable system connecting Chennai to Singapore. The latter is expected to be operational in the fourth quarter of 2029.

The India-Singapore submarine cable route will become one of the world's most critical digital corridors, a high-capacity, low-latency pathway supporting critical enterprise, cloud, and hyperscale traffic between India, Southeast Asia, and global markets. By increasing TGN network capacity, Tata Communications enhances its ability to provide customers with diverse, agile, and high-performance connectivity. These investments will meet the growing demands of the data center (DC) ecosystem, offering enterprises scalable, reliable, and future-proof connectivity between India and Singapore.

These submarine cable systems will further connect to Tata Communications' Indian terrestrial fiber network, enabling seamless backhaul to other parts of India and over 100 data centers nationwide. Combined with Tata Communications' global TGN submarine cable 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 functions across DC and cloud ecosystems. Customers will be able to activate and integrate this capacity into their networks on demand with agility.

Tata Communications operates the largest and most advanced wholly-owned submarine cable fiber network, supporting the internet backbone, encompassing over 500,000 km of submarine fiber and over 200,000 km of terrestrial fiber. In 2025, Tata Communications integrated the new TGN IA2 (Tata Global Network - Intra-Asia 2) submarine cable, enhancing reliability through greater redundancy, reducing latency for faster performance, and increasing network diversity through seamless interconnection with TGN IA.

Genius Wong, Executive Vice President and Chief Technology Officer of Core and Next-Generation Connectivity Services at Tata Communications, stated that as global demand for digital and AI-driven services continues to accelerate, these investments reinforce the company's commitment to building future digital infrastructure at scale. By combining submarine cable capacity enhancements with short-term and long-term strategic investments, Tata Communications is strengthening the reliability, scalability, and performance of connectivity solutions for customers along one of the world's busiest digital corridors. These enhancements align with Tata Communications' long-term strategy to expand its global submarine cable network footprint, deliver outcome-based solutions to customers, and solidify India's position as a digital hub.
