I-2SEA is a new submarine cable system unveiled on 2 July 2026 to boost connectivity between Singapore, India and Malaysia. The consortium includes Lightstorm, Microsoft, Singtel and Tata Communications, while the system supplier is NEC Corporation of Japan. The cable is estimated to span 3,600 kilometres from Singapore to Machilipatnam in India, with a second landing at South Chennai, giving the project two Indian landing points. Machilipatnam offers the shortest subsea access to Hyderabad. Lightstorm is the majority owner, and ASEAN Cableship, based in Singapore, is the marine installation partner. The cable is designed for hyperscalers, GPU infrastructure providers and enterprises running AI training and inference workloads, and Lightstorm expects to expand its connected AI and cloud zones across India from 19 to 29. Completion is targeted for the fourth quarter of 2029.

Background & Context

Submarine communication cables are fibre-optic lines laid across the seabed that carry the overwhelming majority of international internet and data traffic between continents. Landing stations on the coast connect these cables to domestic networks; India's key landings include Chennai and emerging sites like Machilipatnam in Andhra Pradesh. Singapore is a major South-East Asian cable hub. Modern cable systems increasingly serve hyperscalers and GPU infrastructure for artificial-intelligence workloads, making high-capacity, low-latency routes strategically important. NEC Corporation is a Japanese multinational known for telecommunications and undersea network projects.
