Qualcomm, Lumentum and Corning will show a high-density optical interconnect, a way of shuttling data between chips using light rather than electrical signals, built for the next generation of AI hardware.
The platform is pitched to lift chip-to-chip bandwidth while cutting the power draw and latency, the lag between sending data and receiving it, of large-scale AI systems.
The design pools each firm's speciality: Qualcomm's chip-to-chip interface technology, Lumentum's laser-based optical engine and Corning's fibre connectivity.
The market's read
Investors moved on the news in premarket trading.
Corning gained about 3%, Lumentum climbed 2% and Qualcomm added 1.5%, as the market priced in the trio's push into AI-scale networking.
Why light, and why now?
The demonstration builds on short-reach optical links and Lumentum's work on VCSELs, a type of compact, low-power laser used to send data down fibre.
The appeal is bandwidth without the heat. As AI systems grow, the electrical connections between chips become a bottleneck, burning power and adding delay, and optical links are the route vendors are backing to relieve it at the level of the rack and the whole system.
The companies plan to show the platform at ECOC 2026, an optical communications conference, in Málaga.
