Summary of Conference Call Notes Industry Overview - The conference call focuses on the optical module industry, highlighting the impact of AI computing demand on market dynamics and growth potential [1][2][3]. Key Points and Arguments 1. **AI Computing Demand Surge**: The demand for optical modules is driven by a significant increase in AI computing needs, with leading companies raising their 2026 demand forecast for 1.6T optical modules from 7-10 million units to 20 million units, indicating potential for further upward revisions [1][3]. 2. **Competitive Landscape**: At the OCP conference, there is intense competition between CPU and pluggable optical module solutions. The Taiwanese supply chain favors CPU, while the mainland supply chain leans towards CPC/NCC solutions. The training end is sensitive to latency, making CPU more impactful, whereas the inference end prioritizes cost-performance [1][4]. 3. **Growth of GPU Clusters**: The rapid development of large-scale GPU clusters, exemplified by Meta's clear timeline, is expected to further drive demand for AI computing hardware, including optical modules [1][5]. 4. **Strong Financial Performance**: The optical module industry has consistently exceeded market expectations since 2023, with revenue and profit growth. Leading companies have reported significant quarterly net profit increases, suggesting a need for reevaluation of their valuations in the AI era [1][6]. 5. **Optimistic Outlook for 1.6T Optical Modules**: The development outlook for 1.6T optical modules is very positive, with a significantly shortened iteration cycle compared to previous upgrades. This benefits leading manufacturers like Zhongji Xuchuang [1][7]. 6. **Long-term Potential of CPU Technology**: While CPU technology has substantial long-term potential, its short-term impact on pluggable optical module manufacturers is limited. Companies like Xuchuang and Xinyi Sheng are expected to find new business opportunities through internal coupling packaging and silicon photonic chip design [1][8]. 7. **Stock Price vs. Fundamentals**: Current stock price weakness is primarily driven by trading factors rather than deteriorating fundamentals. Companies like Xuchuang and Xinyi Sheng are performing well in the context of 800G and 1.6T introductions, with a favorable outlook for the entire industry chain [2][9]. Additional Important Insights - The optical module industry's valuation is currently seen as reasonable or even low, with leading companies projected to have a valuation of around 12 times by 2026 based on adjusted demand forecasts [1][6]. - Domestic manufacturers are gaining opportunities in the CW light source market as it replaces EML, indicating a shift in the supply chain dynamics [1][7].
