Core Insights - The article highlights the critical role of high-speed interconnect technology in the performance and scalability of AI data centers, with a significant increase in demand for 800G optical transceiver modules projected to reach 24 million units in 2025 and nearly 63 million units by 2026, representing a growth of 2.6 times [2]. Supply Chain Dynamics - The demand for 800G optical transceiver modules has created a severe supply bottleneck at the upstream laser source level, particularly due to Nvidia's strategic monopoly on EML laser chip suppliers, leading to delivery times extending to 2027 [2][3]. - Major suppliers of EML lasers include Lumentum, Coherent, Mitsubishi, Sumitomo, and Broadcom, with the complexity and high production barriers limiting the number of global suppliers [3]. Technology Trends - EML lasers are becoming essential for long-distance transmission due to their ability to maintain signal stability over longer distances, while Nvidia's slow progress in silicon photonics production necessitates reliance on pluggable optical transceiver modules to meet GPU cluster demands [3]. - In contrast, CW (Continuous Wave) lasers, which do not integrate modulation functions within the laser chip, are gaining traction among cloud service providers as a substitute for EML lasers due to their simpler structure and lower production barriers [5]. Market Competition - The production capacity for CW lasers is also constrained by equipment delivery times, making it challenging to meet the high demand driven by AI applications [5]. - The shortage of EML lasers has prompted many laser manufacturers to outsource the back-end processes of laser chip cutting and aging tests to other firms, tightening the overall laser supply chain and leading to expansion plans among laser suppliers [5]. High-Speed PD Demand - The demand for high-speed photodiodes (PD) is rising alongside the need for faster laser sources, with companies like Coherent, Macom, and Broadcom developing 200G PDs to match the transmission speeds of new laser technologies [6]. - Laser manufacturers are prioritizing their crystal growth capacity for laser sources while outsourcing INP crystal growth to specialized foundries to manage production effectively [6]. Industry Implications - The article concludes that the significant demand from AI is not only causing shortages in memory but also tightening the supply of lasers, with Nvidia's monopoly accelerating the adoption of CW lasers and silicon photonics technology among non-Nvidia players [7]. - This capacity competition is reshaping the supply chain dynamics, providing growth momentum for suppliers with advanced compound semiconductor crystal growth and processing capabilities [7].
