Lightstorm Names 3,600km I-2SEA Cable On India-Singapore AI Route
Light Reading reported that Lightstorm is leading Microsoft, Singtel and Tata Communications in the 3,600km I-2SEA subsea cable, with fourth-quarter 2029 service planned for India, Malaysia and Singapore. Financing, pricing and signed customer commitments remain undisclosed.
Lightstorm said it is leading a consortium to build the 3,600km I-2SEA submarine cable between India, Malaysia and Singapore, with the system scheduled for service in 2029 as network capacity for AI infrastructure.
The I-2SEA cable will connect Singapore and Kuala Lumpur directly to Hyderabad and Chennai, with Lightstorm-operated landing stations in Machilipatnam in Andhra Pradesh and South Chennai.
Microsoft, Singtel and Tata Communications are listed as the other consortium partners.
I-2SEA Cable Targets Fourth-Quarter 2029 Service
Lightstorm said the India-Southeast Asia cable is scheduled to be ready for service in the fourth quarter of 2029.
The company said the system is designed for hyperscalers, GPU infrastructure providers and enterprises running AI training and inference.
NEC Corporation has been appointed as system supplier, while ASEAN Cableship Pte Ltd has been named as the marine installation partner.
Lightstorm said the system is already open for capacity commitments, but the consortium did not disclose financial terms for the cable project.
Lightstorm is presenting the cable as more than a general telecom upgrade.
Lightstorm CEO and Managing Director Amajit Gupta said the company wants to extend its SmartNet AI Fabric from data centres and GPU clusters in India into the subsea domain.
Lightstorm Lists 29 AI And Cloud Zones
Lightstorm said the new subsea link is expected to increase its connectivity from 19 AI and cloud zones to 29 zones across India.
The company also said its 30,000km terrestrial network can carry traffic onward from the cable to Hyderabad, Mumbai and more than 80 data centres nationwide.
The Machilipatnam landing point gives the project a specific AI-infrastructure location.
Meta and Alphabet have announced data-centre projects in that part of Andhra Pradesh, and Machilipatnam is described as the shortest direct subsea access point to Hyderabad.
Lightstorm said I-2SEA will support the Singapore-Malaysia-Hyderabad corridor when combined with the company's low-latency backhaul network in India.
The company described the route as strategically critical for AI workloads in the region, but did not publish customer commitments for the system.
Tata Communications Names $152 Million Subsea Investment
Tata Communications confirmed its participation in the I-2SEA consortium earlier in the week.
The company did not name the cable in that announcement, but said the system would connect Chennai and Singapore and target ready-for-service status in the fourth quarter of 2029.
Tata Communications also said it had acquired significant fibre capacity on a Mumbai-Singapore subsea system.
The company described a $152 million strategic investment in subsea infrastructure and said the programme would add 98 Tbit/s of AI-ready capacity to the India-Singapore digital corridor.
Genius Wong, Tata Communications' executive vice president of Core and Next-Gen Connectivity Services and chief technology officer, said the investments are intended to improve reliability, scalability and performance across one of the world's busiest digital corridors.
The consortium has not disclosed I-2SEA project financing, capacity prices, signed customer commitments, construction milestones, permitting status or the first buyers for the new subsea cable.
