Summary of Conference Call on Silicon Photonics and CPO Industry Trends Industry Overview - The conference focuses on the trends in the Silicon Photonics (SiPh) and Co-Packaged Optics (CPO) industries, particularly the advancements in CPO technology and its implications for the optical module market [1][2]. Key Points and Arguments CPO Technology Development - NVIDIA has updated its CPO switches to a 200G platform, indicating that the CPO replacement will not deepen at the 100G platform, with future penetration rates centered around 1.6T optical modules [1][2]. - By 2026, NVIDIA aims to promote CPO applications in scale-out scenarios, while scale-up replacements face higher barriers such as SerDes rates and CoWoS industry collaboration [1][2]. CPO's Impact on Optical Modules - Two high-power CW light sources can replace one 1.6T optical module. For instance, NVIDIA's Quantum switch, which has a capacity of 51.2T, originally required 72 1.6T optical modules but can now operate with only 144 CW light sources, resulting in a fourfold reduction in laser requirements [1][6]. Competitive Landscape - Lumentum and Coherent predict that pluggable optical modules will remain the main product from 2026 to 2027, covering rates of 1.6T and 3.2T. CPO's advantages will only manifest in specific scenarios, such as AI supercomputers with over 100,000 GPUs [2][3]. Optical Module Industry Fundamentals - Lumentum has initiated 6-inch wafer production for EML, quadrupling output and halving costs, which is expected to alleviate concerns regarding 1.6T optical module capacity by 2026 [2]. - Major tech companies like Amazon, Google, Microsoft, and Meta are projected to have capital expenditures of $260 billion in 2026, a 60% year-on-year increase, ensuring short-term demand for optical modules [2][11]. Investment Logic and Valuation - Leading companies like Xuchuang and Xinyi have not reached a strong consensus on profit forecasts related to 1.6T optical module deliveries, leading to attractive valuations. Signals of upstream EML capacity expansion are expected to shift market sentiment from capacity concerns to demand optimism [2][11]. CPO/OCS Technical Progress - CPO technology is advancing in scale-out scenarios, with NVIDIA's 200G platform already having products available. However, the TCO advantage of CPO is only significant in ideal scenarios with large-scale clusters [3][10]. - The scale-up scenario is seen as the core direction for CPO, but it requires advancements in 400G SerDes and CoWoS packaging, with no clear product forms currently available [3][10]. Industry Chain and Investment Strategy - Key players in the CPO/OCS industry include NVIDIA's partners such as Broadcom, Corning, and TSMC. Investment strategies should focus on core players within the industry chain [4][5]. - The investment strategy suggests focusing on confirmed targets within the CPO/OCS sector, avoiding high-risk investments, and capitalizing on market fluctuations through strategic positioning [5][7]. Market Sentiment and Future Outlook - The sentiment around CPO is currently weak, impacting the demand and long-term valuation of optical modules. However, the expected capital expenditures from leading tech companies provide a solid foundation for short-term demand [11][12]. - The market is expected to experience high volatility as new technologies progress, and investors are advised to remain cautious and strategic in their approach to CPO and optical module investments [12][13]. Additional Important Insights - Discussions around the potential use of CPO in the RubinUltra L2 layer remain speculative, with no official confirmation. If implemented, it would not affect the demand for external scale-out optical modules [8][9]. - The NPO technology is progressing rapidly, with manufacturers pushing for samples and advancements, potentially offering competitive advantages over CPO in terms of production feasibility and cost [10].
