Tata Communications announced strategic investments in subsea cable infrastructure to bolster its connectivity solutions between India and Singapore, catering to the growing demands of AI hubs. The company is enhancing its Tata Global Network (TGN) by integrating a new subsea cable system between Mumbai and Singapore and investing as a consortium member in a new subsea cable system connecting Chennai to Singapore, which is expected to be Ready for Service (RFS) in Q4 2029.
These investments aim to provide enterprises with secure, high-speed, dynamic, and low-latency infrastructure, strengthening the digital corridor between the two regions. Genius Wong, EVP of Core and Next-Gen Connectivity Services and CTO, stated that these investments reinforce the company's commitment to building future-ready digital infrastructure at scale. The enhancements align with Tata Communications’ strategy to expand its global subsea network footprint and reinforce India’s position as a Digital Hub.
