Summary of Conference Call Records Company Overview - The company discussed is 太辰光 (Tachyon), a leading manufacturer of MT ceramic inserts in China, focusing on the MPO (Multi-fiber Push On) market and emerging technologies like CPO (Co-Packaged Optics) and GPU direct light technology [1][2][3]. Industry Insights - The MPO market is expected to grow rapidly, with projections indicating a market size exceeding $3 billion by 2026, driven by the high growth of the optical module industry [1][9]. - The MPO industry has a relatively simple structure, with major customers including North American cloud providers like Google, Microsoft, Amazon, and Meta, who rely on wiring companies for comprehensive solutions [5]. Key Points and Arguments - 太辰光 holds a market share of 10%-15% in the MPO market, positioning itself as a significant supplier [1][9]. - The company has achieved improved gross and net profit margins through self-supply of core components, which have been certified by major clients and are now in mass production [1][9]. - CPO switches are gaining attention for their high bandwidth density and low energy consumption, with NVIDIA planning to mass-produce CPO switches in the second half of 2025, indicating increasing market penetration [1][10]. - MMC (Miniature Multi-fiber Connector) connectors are becoming a preferred choice for CPO switches due to their smaller size, allowing for higher density fiber arrangements [1][11]. Emerging Technologies - The company is actively investing in new technologies such as CPO and GPU direct light, collaborating with high-quality clients to prepare for future technology implementation [2][15]. - GPU direct light technology could significantly increase the demand for cables and connectors, as each GPU may require 60 to over 100 fibers in the future [13][14]. Historical Development and Future Potential - Established over 20 years ago, 太辰光 quickly became an industry leader in MT ceramic inserts and has continuously reduced costs, contributing significantly to broadband network development in China [7][8]. - The company has a diversified product line, including MPO/MTP jumpers, low-speed optical modules, and PLC/AWG planar waveguide products, with major clients like Corning and Huawei [6]. Additional Important Insights - The company is not significantly affected by tariffs, as partnerships with large American firms like Corning provide tariff exemptions [3][15]. - The internal connection lines in the CPU era are expected to evolve, requiring more compact designs for efficient installation and maintenance [12]. This summary encapsulates the key insights from the conference call, highlighting the company's strategic positioning within the MPO market and its proactive approach to emerging technologies.
