As technology firms ramp up investments in high-speed AI data center construction, optoelectronic device manufacturer Lumentum—which counts NVIDIA among its investors—is experiencing unprecedented strain on its production capabilities, with orders already secured through 2029. Currently, Lumentum anticipates being unable to fulfill approximately 70% of the demand for certain products next year. Even by 2028, a 30% demand gap for some products is projected to persist. Despite the company's full-throttle efforts to expand production, meeting customer needs remains a formidable challenge, and achieving a supply-demand equilibrium appears to be a long way off. NVIDIA has previously invested $2 billion each in Lumentum and its competitors. According to Lumentum's executive (the term "person in charge" is retained here for HTML fidelity, though it can be contextually translated as "executive" or "leader"), establishing new production capacity typically requires 3 to 5 years. To safeguard their core supply chains, major technology companies are aiding suppliers in scaling up production through long-term agreements, sharing capital expenditure risks, and other collaborative measures.
