Impact on Procurement
This agreement signals a move toward a single company offering a broad range of electrical and optical interconnect technologies for AI servers. However, since the acquisition has not yet been completed, it cannot be concluded that the sources of supply, prices, delivery times, or warranty terms for Lumentum products will change immediately based solely on this announcement.
There has also been no announcement that existing supply constraints will be resolved in the short term as a result of the acquisition agreement. For 1.6T optical transceivers, InP lasers, and CPO/ELS-related components, it is necessary to confirm supply quotas and guaranteed delivery dates for each specific part number.
Actions Purchasing Personnel Should Take
- For existing products using Lumentum components, verify whether there have been any changes to supply contracts, certifications, warranties, or communication channels for EOL and PCN notifications.
- For projects in 2027–2028, distinguish between the expected completion of the acquisition and the timing of component requirements, and confirm supply quotas through current manufacturers and authorized distribution channels.
- For projects combining Marvell’s DSPs, switches, and custom silicon with Lumentum’s optical components, do not confuse future integrated products with current products.
- Do not evaluate alternatives based solely on data transfer speed; also assess wavelength, distance, form factor, power consumption, thermal management, firmware, and interoperability.
Practical Comments from AI Components
Acquisition agreements provide insight into medium- to long-term product portfolios and supply strategies. However, no immediate changes to procurement terms have been confirmed at this time. Rather than rushing to purchase, verify delivery dates, supply quotas, prices, and approval for alternatives for certified part numbers where supply constraints persist.

Impact on Procurement
Demand for AI server components may extend beyond GPUs and HBM to include 1.6T optical transceivers, laser diodes, switches, NICs and DPUs, and high-speed copper cables. However, increased shipments of AI accelerators do not necessarily correlate with demand for network components.The required quantities vary depending on the network configuration, connection method, and bandwidth.
Furthermore, it is not possible to conclusively determine that there will be supply shortages or price increases across all manufacturers and model numbers based solely on market growth forecasts for 1.6T products. Supply constraints regarding certain optical components from Lumentum and the lead times for finished optical transceivers must be assessed separately.
Actions Procurement Personnel Should Take
- For the 2027 project, clarify the specifications for 800G and 1.6T, pluggable vs. CPO, transmission distance, and form factor.
- Categorize laser diodes, finished modules, switches, NICs/DPUs, and cables, and confirm supply quotas and guaranteed delivery dates for each specific part number.
- Inquire with authorized distributors and manufacturers regarding secured quantities, partial delivery terms, quote validity periods, and whether any price revision notices have been issued.
- Do not judge alternatives based solely on speed; evaluate communication standards, wavelength, distance, power consumption, heat dissipation, and interoperability with host equipment.
- When utilizing overseas inventory, verify the lot number, manufacturing date, storage conditions, firmware, traceability, and warranty terms.
Practical Comments from AI Components
The key point here is that the growth of AI networks is expected to extend beyond optical transceivers to include switches, NICs/DPUs, and copper cables.

Market Research Information
The following updates are from before October 13, 2026.
For AI servers, procurement management covers not only GPUs and HBM but also optical communication laser components and modules. It is important not to confuse Lumentum’s supply outlook with the confirmed delivery dates for individual part numbers.
Overview of Supply Shortages
A Bloomberg report on October 9 indicated that for some products, supply will fall short of approximately 70% of demand through 2027, while for another product group, supply will fall short of approximately 30% of demand through 2028. These figures apply to different product groups and time periods.
Supply constraints for AI servers are not limited to GPUs and HBM.In an interview with Bloomberg on October 9, 2026, Lumentum CEO Michael Hurlston explained that the company’s production capacity for optical components is fully booked through early 2029. Supply conditions vary by product group. This does not indicate specific delivery dates for all optical components.
Confirmed Facts
On March 2, 2026, NVIDIA and Lumentum announced a strategic agreement regarding the joint development of optical communication technology and the expansion of production capacity. NVIDIA has announced a $2 billion investment in Lumentum.
On March 26, 2026, Lumentum announced plans to increase production of InP (indium phosphide) lasers at its manufacturing facility in North Carolina, U.S. Production is scheduled to begin in mid-2028, though the exact timing has not been finalized.
According to the company’s financial results dated August 11, 2026, revenue for the fourth quarter of the fiscal year was approximately US$1.006 billion. The report also mentions demand for 1.6T optical modules, lasers for CPO, and ELS modules. While revenue figures are actual results, they do not represent future delivery schedules by product.
Impact on Procurement
Laser diodes and finished optical transceivers are separate products. Even if supply capacity is tight for some of Lumentum’s products, this does not necessarily mean that all 800G and 1.6T optical modules will have the same lead time. Price increase rates and standard lead times must be verified on a part-number-by-part-number basis.
Procurement Checkpoints by Product
| Product Groups | Items to Verify |
|---|---|
| Laser Devices | Part Number, Wavelength, Optical Output, Supply Capacity, Required Evaluation |
| 800G and 1.6T Optical Modules | Communication Standards, Distance, Mounting Configuration, Compatibility with Host |
| CPO and ELS-Related Components | Equipment in Which Installed, Mass Production Timeline, Maintenance Conditions, Approval for Substitutes |
| Overseas Inventory | Manufacturer, Lot, Storage Conditions, Traceability |
Actions to Be Taken by Purchasing Personnel
- Verify the complete part number and distinguish between laser elements, finished modules, and CPO components.
- Confirm the secured quantity, response lead time, partial delivery terms, and quote validity period with the manufacturer and authorized distributors.
For critical projects in 2027–2028, verify the availability of long-term supply quotas. When considering alternatives, verify the wavelength, output, communication standards, communication distance, power consumption, thermal design, host device interoperability, and customer approval.
When procuring from overseas inventory, verify the lot, manufacturing date, storage conditions, traceability, authenticity, and warranty. Displayed inventory levels do not necessarily guarantee continuous mass-production supply.
How to Interpret the Supply Outlook Through 2029
A statement that production capacity is fully booked through early 2029 indicates that supply constraints are likely to persist. However, demand forecasts and order status are subject to change. This does not confirm that all products will be unavailable or that across-the-board price increases will occur.
Practical Comments from AI Components
To ensure the continued mass production of AI servers, it is essential to confirm the supply of optical communication components in addition to GPUs and HBM. On the other hand, you should not rush to purchase all products based solely on media reports. We recommend verifying the required quantities, supply quotas, delivery dates, and availability of alternatives for certified critical part numbers.
