Tata Communications Limited announced investments in subsea cable infrastructure to strengthen the India-Singapore digital corridor. The investments target growing bandwidth and AI-driven data demands across Asia.
The company is enhancing its Tata Global Network by integrating two subsea cable systems: the MIST Cable System between Mumbai and Singapore with approximately 20 Tbps capacity, and Project CS connecting Chennai to Singapore with about 78 Tbps capacity. These additions will be part of the existing network infrastructure.
Total investment for these projects is USD 152 million. USD 63 million is allocated for MIST in FY 2027, and USD 89 million for Project CS from FY 2027 through FY 2031. Financing will come entirely from internal accruals.
MIST is expected to reach readiness for service in Q4 FY 2027, with initial capacity of 2 Tbps to be scaled to 20 Tbps in future years. Project CS has a readiness for service timeline of Q3 FY 2031, starting with 4 Tbps and expanding to 78 Tbps over subsequent years.
The new subsea cables will connect with Tata Communications' terrestrial fiber network for seamless onward connectivity to over 100 data centers nationwide. This integration supports the company's IZO connectivity solutions for data center and cloud ecosystems.
Tata Communications operates the largest wholly-owned subsea fiber network, spanning 500,000+ km of subsea optical fiber and 200,000+ km of terrestrial fiber. The current global subsea capacity is approximately 270 Tbps with utilization of about 172 Tbps. The company serves 300 of the Fortune 500 companies and connects businesses to 80% of the world's cloud giants.
