800G of optical modules in stock

The 800G optical module market is experiencing strong demand, with InnoLight and Eoptolink capturing 60% of current high-volume orders, while overall supply remains constrained by AI-driven data center growth.

Current Supply and Major Suppliers

The surge in AI infrastructure, particularly Nvidia's expansion of GPU clusters, has significantly increased demand for 800G optical modules. In 2026, Nvidia alone is expected to increase its 800G module orders by 35%, with InnoLight and Eoptolink securing 60% of these orders, and the remaining 40% distributed among U. S. vendors like Coherent, Lumentum, and Broadcom.

This concentration indicates that stock availability is largely dependent on these leading suppliers.

Market Size and Growth

The global 800G optical module market was valued at $4. 8 billion in 2025 and is projected to reach $28. 6 billion by 2034, growing at a CAGR of 22.

1%. The market is driven by AI, machine learning, hyperscale cloud operators, and the expansion of 5G and beyond-5G networks. Hyperscalers such as AWS, Microsoft Azure, Google Cloud, and Meta are major consumers, collectively investing hundreds of billions in data center infrastructure, with optical modules forming a critical component.

Stock Considerations

Due to high demand, short-term stock may be limited, especially for large-scale deployments like Nvidia's GB200 servers, which require tens of thousands of 800G DR8 modules per cluster. The market is also influenced by the maturation of coherent optics, silicon photonics, and co-packaged optics, which are gradually increasing production efficiency and reducing costs. However, supply remains tight for immediate procurement, particularly for high-volume enterprise or hyperscale orders.

Regional and Vendor InsightsAsia-Pacific dominates production, with major suppliers like InnoLight and Eoptolink headquartered in the region. North America relies on a mix of domestic and imported modules, with companies like Coherent, Lumentum, and Broadcom contributing to supply. Europe and Latin America are emerging markets, with adoption increasing as cost-per-gigabit declines and ecosystem readiness improves.

Practical Implications

For organizations seeking 800G modules, early engagement with suppliers is critical due to high demand and limited immediate stock. Customized solutions and pre-orders are often necessary to secure modules for large-scale AI or data center deployments. Market trends suggest that while supply will gradually expand, short-term availability may remain constrained, particularly for the most advanced 800G DR8 and coherent modules.

In summary, 800G optical modules are in high demand with limited immediate stock, dominated by InnoLight and Eoptolink, and the market is expected to grow rapidly over the next decade, driven by AI, hyperscale cloud, and next-generation networking infrastructure.
