Asia Pacific connectivity provider Lightstorm is to launch a new submarine cable system connecting India, Malaysia, and Singapore in partnership with Microsoft, Singtel, and Tata Communications.The cable system, I-2SEA, will be primarily aimed at supporting hyperscalers, GPU infrastructure providers, and enterprises with AI training and inference workloads across the India-Southeast Asia corridor.I-2SEA is being developed under a consortium and joint-build agreement between Lightstorm, Microsoft, Singtel, and Tata Communications. NEC is the system supplier and ASEAN Cableship is the marine installation partner.The cable system will link Hyderabad and Chennai on the east coast of India to Singapore and Kuala Lumpur, Malaysia. It will have dual landings in India, one at Machilipatnam and another in South Chennai.It will also use LIghtstorm’s SmartNet AI Fabric, which the company says offers low-jitter, loss-optimized transport across data centres, cloud hubs, and distributed AI zones.“Lightstorm works around a single mission: interconnecting intelligence,” said Amajit Gupta, group CEO and managing director, Lightstorm.“As majority owner of I-2SEA and with SmartNet AI Fabric already delivering AI-ready transport across data centers and GPU clusters in India, we can now offer the natural extension of that platform into the subsea domain. On our network, AI regions across India, Malaysia, and Singapore will be connected by a single, purpose-built, end-to-end system – engineered for the performance and scale that AI infrastructure requires.”Earlier this week, Tata Communications announced it would invest in two subsea cable systems between India and Singapore. This included a new subsea system between Mumbai and Singapore, as well as participation as a consortium member in a cable system between Chennai and Singapore.Tata said it expects the Chennai-Singapore subsea cable system to be Ready for Service (RFS) in Q4 2029.
