CPO Industry Update Summary Industry Overview - The CPO (Co-packaged Optics) supply chain has secured substantial orders, with mass production expected in H2 2026 and a projected market penetration rate of 10% by 2027, equating to approximately 100,000 units shipped. By 2030, the long-term penetration rate is anticipated to reach 40%-50% [2][3]. Core Insights and Arguments - **Market Impact**: The CPO technology is not expected to significantly impact the 1.6T optical module and copper cable markets in 2026-2027 due to low absolute shipment volumes and high overall capital expenditure in the industry. However, a notable replacement effect is expected post-2028 as the 3.2T era begins [2][3][4]. - **Growth Projections**: CPO shipments are projected to grow from approximately 500 units in 2025 to 20,000 units in 2026, achieving a market penetration rate of about 2%. By 2027, shipments could increase by 4 to 5 times, reaching a 10% penetration rate [3][4]. - **Competitive Landscape**: The CPO technology will compete directly with 3.2T optical modules in the high-end market starting in 2028, as its performance and power consumption advantages become more pronounced [4]. Key Components and Market Dynamics - **Optical Engine**: The optical engine is a core component, with a single 1.2T switch valued at approximately $30,000. The market for optical engines could reach $40 billion by 2030, surpassing the current optical module market size [2][5]. - **CW Light Source Module**: The value of CW light source modules is approximately ten times higher than traditional solutions, with gross margins of 40%-50%. This segment is primarily dominated by overseas leaders like Lumentum and Coherent, while domestic players like Yuanjie Technology are seeking partnerships to enter the North American supply chain [2][5]. - **Passive Components Demand**: The demand for passive components is surging, with each device requiring thousands of optical fibers, leading to increased demand for optical connectors (e.g., Zhishang Technology), FAU couplers (e.g., Tianfu Communication), and flexible optical boards (e.g., Tai Chen Light) [2][5][6]. Additional Important Insights - **Supply Chain Changes**: CPO technology restructures traditional plug-and-play optical modules into independent modules, significantly altering product forms and supply chain dynamics. This change presents opportunities for traditional optical module manufacturers and core component suppliers to participate in the new market landscape [4][5]. - **Future Opportunities**: Domestic manufacturers have a high participation rate in the passive components sector, indicating substantial growth opportunities in the future as the CPO market expands [6].
