Domestic 800G optical module companies
U.S.-based companies capable of producing 800G optical modules include Coherent, Lumentum, and Broadcom, all of which supply high-speed modules for AI, data center, and telecom applications.
Key Domestic Manufacturers
Coherent – A leading U.S. supplier of 800G optical modules, Coherent focuses on coherent pluggable modules and has been actively shipping L-band SFP-DD 800G modules for AI-driven data center applications, with strong growth expected in 2025 . Lumentum – Another major U.S. manufacturer, Lumentum provides critical optical components and 800G modules for both datacom and telecom markets. They are recognized for their high-volume production capabilities and advanced optical technologies . Broadcom – Broadcom supplies essential optical components, including DSPs and drivers used in 800G modules. While primarily a component supplier, their technology underpins many domestic 800G module assemblies .
Technology and Production Notes
800G optical modules can be based on silicon photonics or traditional EML (Electro-Absorption Modulated Laser) designs. Silicon photonics modules typically use fewer chips (two silicon photonics chips with four CW light sources) compared to traditional 8-EML chip designs, enabling more scalable and cost-effective production . These U.S. companies are positioned to meet the growing demand driven by AI infrastructure, hyperscale cloud operators, and high-performance computing, with production scaling to support both 800G Ethernet and emerging 1.6T modules .
Market Context
The 800G optical module market is expanding rapidly, with domestic suppliers playing a critical role in meeting demand from cloud providers like Amazon Web Services, Microsoft Azure, and Google Cloud. The ecosystem includes module assemblers, laser chipmakers, and system integrators, ensuring that U.S.-based production can support both domestic and international deployments . In summary, Coherent, Lumentum, and Broadcom are the primary domestic companies capable of producing 800G optical modules, leveraging advanced silicon photonics and coherent optics technologies to meet the high-speed data transmission needs of modern AI and telecom networks.
