Tata Communications has announced strategic investments to strengthen digital connectivity between India and Singapore through the expansion of its subsea cable infrastructure. The company will invest Rs. 1,442.33 crore (US$ 152 million) to enhance its Tata Global Network (TGN), supporting the rapidly growing demand for artificial intelligence (AI), cloud computing and digital services across the region. As part of the initiative, Tata Communications will integrate the MIST Cable System between Mumbai and Singapore by adding 20 Tbps of capacity with an investment of Rs. 594.47 crore (US$ 63 million). In addition, it will participate as a consortium member in Project CS, a new subsea cable system connecting Chennai and Singapore, contributing 78 Tbps of capacity through an investment of Rs. 839.80 crore (US$ 89 million). Together, these projects will add approximately 98 Tbps of network capacity to the India-Singapore corridor.
The investments are aimed at creating AI-ready digital infrastructure capable of meeting increasing enterprise demand for high-speed, resilient and low-latency connectivity. The enhanced subsea network is expected to support data-intensive applications, cloud services and next-generation digital ecosystems while strengthening connectivity between two emerging AI hubs. According to the company, the MIST Cable System is expected to be ready for service in Q4 FY27, while Project CS is targeted for completion in Q3 FY31. Tata Communications stated that the expansion reinforces its long-term commitment to building future-ready digital infrastructure at scale and enabling seamless cross-border connectivity for enterprises. The initiative is also expected to enhance network resilience and strengthen India's role in supporting regional digital transformation and the growing data centre ecosystem across Asia.
