Tata Communications will invest in two key subsea cable systems between India and Singapore as part of a plan to strengthen connectivity for AI.These investments will consist of a new subsea cable system between Mumbai and Singapore, as well as investments as a consortium member in a new subsea cable system between Chennai and Singapore.Tata said the investments will enhance its Tata Global Network (TGN) capabilities and address growing bandwidth and AI-driven data demands from enterprises across Asia and globally.“Together, these investments will meet the growing needs of the data center ecosystem, offering enterprises a scalable, reliable & future-ready connectivity between India and Singapore,” the company said in a statement.Tata expects Chennai-Singapore subsea cable system to be Ready for Service (RFS) in Q4 2029. No expected RFS date for the Mumbai-Singapore connection was given.The cable systems will connect with Tata’s India Terrestrial fiber network for onward connectivity to other parts of the country.“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 of core and next-gen connectivity services, and CTO, Tata Communications.“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 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.”Last year, Tata integrated the TGN Intra-Asia 2 submarine cable into its network, supporting connectivity across Singapore, Hong Kong, and Japan.Tata has been investing in its cloud services in recent years. It operates data centers in 44 locations worldwide, including India, Singapore, the UK, Portugal, and the US.
