Sterlite Technologies announced a multi-year Product Award Letter (PAL) valued at more than $1 billion to supply optical connectivity products for AI data center build-outs in the United States. The agreement, awarded through one of STL’s subsidiaries, supports a hyperscaler’s expanding AI infrastructure footprint and further positions STL in the rapidly growing AI data center connectivity market.
The company said the engagement will leverage its vertically integrated “glass-to-data-center” manufacturing model, spanning optical fiber, optical cable, and connectivity systems. STL has increasingly focused on AI infrastructure requirements, including ultra-high-density fiber architectures designed to support GPU-intensive AI clusters and large-scale east-west traffic patterns inside hyperscale facilities. The company emphasized its in-house R&D and co-development approach for next-generation optical networking systems.
STL recently introduced its Neuralis AI Data Center portfolio targeting hyperscale AI deployments. The offering includes ultra-high-density pre-terminated fiber systems for AI whitespace connectivity and its Celesta IBR cable series, which supports up to 6,912 fibers in compact cable designs aimed at high-capacity data center interconnect (DCI) environments. The company said the products are designed to address escalating bandwidth and fiber density requirements associated with large AI training and inference clusters.
- Multi-year Product Award Letter exceeds $1 billion in value
- Agreement supports AI data center deployments in the United States
- STL will provide optical connectivity infrastructure products
- Neuralis AI Data Center portfolio targets hyperscale GPU clusters
- Celesta IBR cable platform supports up to 6,912 fibers
- STL highlighted its vertically integrated “glass-to-data-center” manufacturing capability
“Under this agreement, STL, through its optical solutions, will support building AI data center infrastructure in the US for this hyperscaler,” said Ankit Agarwal, Managing Director of STL. “We are enabling connectivity backbone for the AI data centers.”
🌐 Analysis: The award reflects accelerating investment in optical infrastructure for AI data centers, where hyperscalers are redesigning network architectures around high-density GPU clusters and large-scale AI fabrics. AI training systems require significantly higher fiber counts, lower latency, and dense optical interconnects between compute, storage, and switching layers. Suppliers spanning optical fiber, transceivers, structured cabling, and co-packaged optics are seeing increased demand tied to AI infrastructure expansion.
