AI Demand Strains Supplies of Lasers, Fiber, and Other Optical Tech

Why It Matters

Shortages in optical components threaten the pace of AI‑driven data‑center expansion, while the rise of CPO technology signals a strategic shift that could redefine future infrastructure investments.

Key Takeaways

• AI data centers driving global shortage of optical transceivers and lasers
• Optical fiber prices surge as capacity locked by large data‑center orders
• Fujikura invests $1.9 billion to triple production for U.S. demand
• CPO technology could reshape transceiver market, targeting $20 billion by 2036
• Shares of InP wafer maker IQE jump over 800% this year

Pulse Analysis

The surge in artificial‑intelligence workloads has exposed a hidden bottleneck in the tech ecosystem: optical communications hardware. While memory chips and CPUs have dominated headlines, the rapid scaling of AI data centers demands ever‑faster inter‑server links, driving up demand for lasers, indium‑phosphide substrates, and high‑capacity fiber. Suppliers report that existing production lines can barely meet a fraction of the orders, pushing prices upward and prompting customers to secure long‑term allocations. This pressure mirrors earlier semiconductor shortages, but the optical segment is less diversified, making supply constraints more acute for firms reliant on high‑bandwidth connectivity.

To address the gap, legacy players are accelerating capacity expansions. Corning announced a tenfold increase in U.S. fiber output after signing a multiyear deal with Nvidia, while Japan’s Fujikura is investing roughly $1.9 billion to triple its production lines for American clients. Market forecasts underscore the opportunity: Trendforce projects AI‑related optical transceiver revenue to climb from $16.5 billion in 2025 to $26 billion in 2026, and IDTechEx expects the co‑packaged optics (CPO) market to exceed $20 billion by 2036 with a 37% CAGR. These figures highlight a dual growth trajectory—traditional pluggable modules remain essential for the near term, even as CPO designs promise higher density and lower latency.

The strategic implications are profound. Companies that secure supply of lasers and InP wafers, such as IQE, Coherent, and Lumentum, have seen their stocks soar, reflecting investor confidence in a prolonged demand surge. At the same time, the emergence of CPO technology could eventually reduce reliance on external transceivers, reshaping the value chain and creating new competitive dynamics. For data‑center operators, balancing immediate component shortages against long‑term CPO adoption will be critical to maintaining cost‑effective scalability. Stakeholders across the ecosystem must therefore collaborate on design, testing, and manufacturing standards to mitigate risk and capture the upside of this optical transformation.
