Tata Communications has announced an investment of USD152 million to expand its subsea cable infrastructure between India and Singapore, strengthening one of Asia’s busiest digital corridors to support growing demand for cloud services, artificial intelligence (AI) workloads and enterprise connectivity. The investment will add approximately 98 Tbps of new capacity through two subsea cable projects linking Mumbai and Chennai with Singapore, with both initiatives fully funded through internal accruals.
The company will invest USD63 million in the MIST subsea cable system connecting Mumbai and Singapore, which is expected to enter service in the fourth quarter of FY2027 and provide an additional 20 Tbps of capacity. Tata Communications will also invest USD89 million as a consortium member in Project CS, a new Chennai–Singapore subsea cable scheduled for completion in the third quarter of FY2031, adding approximately 78 Tbps of capacity. The enhanced infrastructure will integrate with Tata Communications’ terrestrial fibre network, extending connectivity to more than 100 data centres across India.
The expanded India–Singapore route is designed to provide high-capacity, low-latency connectivity for enterprise, cloud and hyperscale customers across India, Southeast Asia and global markets. The investment supports Tata Communications’ long-term strategy to expand its global subsea network and strengthen India’s position as a regional digital hub. The company currently operates approximately 270 Tbps of subsea network capacity across more than 500,000 km of subsea fibre and 200,000 km of terrestrial fibre infrastructure.
