NVIDIA has committed $4 billion to invest in two major optical communication leaders, aiming to secure critical production capacity in advance for the upcoming "optical interconnection" era in next-generation AI computing architecture.
On March 2 local time, NVIDIA announced multi-year partnerships with optical component manufacturers Coherent and Lumentum. The collaborations include joint research and development in optical technologies, priority arrangements for future production capacity and supply, as well as "multi-billion dollar" multi-year procurement commitments from NVIDIA. Concurrently, NVIDIA is investing $2 billion in each company to support their research and development, future production capacity, and operational expansion within the United States.
According to analysis, the structure and intent of the two deals are "substantially similar": both are non-exclusive, multi-year advanced optical partnerships; both include "procurement commitments in the billions of dollars"; NVIDIA is investing $2 billion in each of Coherent and Lumentum to expand US manufacturing capacity and support R&D; and both companies mentioned that NVIDIA will receive common stock in exchange for this investment.
A recent report highlights that the core objective of NVIDIA's investment is "supply protection" for Co-Packaged Optics (CPO). The report states, "The primary driver for the deals is to secure supply for NVIDIA across both scale-out and scale-up types of CPO." This is viewed more as "pre-stocking" materials for the larger-scale era of optical connectivity rather than a response to short-term supply-demand fluctuations.
This strategy is akin to reserving an entire orchard before the fruit ripens. As AI cluster scales increase, traditional pluggable optical modules will face physical limits in power consumption and density. CPO technology, which integrates optical components directly with GPUs, becomes an inevitable trend. CPO integrates pluggable transceivers directly inside switches, potentially reducing hardware procurement costs for data center operators and significantly cutting network energy consumption.
The investment focus is on specific areas: lasers, Indium Phosphide (InP) production lines, and US-based factory construction. Details suggest NVIDIA is betting not on generic "optical interconnect modules" but rather on key light source and core component capacity needed for CPO.
Analysis indicates that "we believe a large portion of this deal is targeted at 400mW Continuous Wave (CW) lasers." It is also emphasized that the Coherent partnership covers multiple products, "including ultra-high power CW lasers for CPO."
Specific details on fund allocation were revealed. NVIDIA's investment will primarily be used to expand the US manufacturing capabilities of both companies and support R&D.
For Coherent, the $2 billion in unrestricted funds will be prioritized for capital expenditure, specifically to expand its Indium Phosphide (InP) production capacity at its Sherman, Texas facility. The multi-billion dollar procurement commitment is expected to commence in early 2027 and continue through 2030.
For Lumentum, a significant portion of the funds will be used to build a "brand new" wafer fab in the United States. Lumentum had previously disclosed an expected "hundreds of millions of dollars" procurement order for the first half of 2027; NVIDIA's new order is entirely incremental, with the incremental revenue expected to materialize from the second half of 2027 onwards.
The revenue realization timeline appears to be "further out." The "multi-year, multi-billion dollar procurement commitment" for Coherent is expected to start in early 2027, with the partnership "extending through 2030." For Lumentum, the new collaboration is incremental to the existing order: the previously disclosed "hundreds of millions" procurement order is expected in H1 2027, while new revenue from this deal is more likely to materialize from H2 2027 and beyond.
This timing helps explain why NVIDIA's move is interpreted as "pre-booking capacity." CPO aims to solve interconnection bottlenecks for AI clusters requiring higher bandwidth and lower power consumption, with its adoption resembling an industry migration rather than a single-quarter inventory build.
For the industry chain, electrical interconnect technologies are not expected to disappear immediately, but signals for "phased substitution" are stronger. The market might see two quick reactions: first, this could be negative for companies related to electrical connectivity, as securing supply suggests nearer-term advancement for short-reach CPO links, though electrical interconnects will still hold significant importance in the short term, with impacts felt more in long-term structural changes. Second, the deals further reinforce the theme of US domestic supply chain expansion. The transactions are not directly aimed at optical modules but might lead to more cautious market sentiment towards some "non-US" module manufacturers.
Additionally, the timing of the deal disclosure is "not surprising," as NVIDIA is "likely to discuss new CPO solutions at the upcoming GTC conference." If clearer product roadmaps are revealed at GTC, the implications of this "capacity lock-in" could be used by the market to reassess the CPO adoption timeline.
