Summary of the Conference Call for Shijiazhuang Shijia Photonics Company Overview - **Company**: Shijiazhuang Shijia Photonics - **Industry**: Optical Communication and Photonics Key Points and Arguments 1. **Product Development**: Progress has been made in 800G and 1.6T FAU products, with client validation completed. CW light source clients have also completed validation but are still in small batch delivery phase, with expectations for large orders in the second half of 2026 [2][3][4] 2. **Revenue Structure**: Over 70% of revenue comes from optical chips and devices, approximately 15% from indoor optical cables, and the remaining 15% from other businesses. AWG components have a high gross margin, while MPO jumpers have a relatively low margin [2][5] 3. **MPO Business Growth**: MPO business is experiencing rapid growth but is limited by production capacity. The company is expanding production through new factory leases, equipment installation, and worker recruitment, although specific growth rates are difficult to predict [2][6] 4. **AWG Product Line Performance**: The AWG product line showed stable growth in Q2, with no significant changes in order volume, possibly due to seasonal fluctuations from different client solutions. The company is expanding AWG capacity to maximize utilization and gross margin [2][6][7] 5. **High-Speed DML Products**: Breakthroughs have been achieved in high-speed DML products (e.g., 25G and 50GPON), with EML samples (100G, 200G, and 50GPON) launched [2][8] 6. **Yield Improvement**: Continuous improvements in yield across product lines have been implemented, particularly starting from the AWG pilot, which has positively impacted gross profit margins [2][9] 7. **Inventory Levels**: The company has over 500 million yuan in inventory, primarily due to high stock levels of indoor optical cables and MPO products, influenced by international market shortages and tariff policies [2][4][12] 8. **Capital Expenditure**: Capital expenditure for the first half of 2025 was 83 million yuan, significantly up from the same period in 2024, driven by increased orders and capacity expansion investments [2][19] 9. **Production Capacity**: The company is confident in meeting market demand across various product lines, with specific focus on AWG and DFB products, which are currently at full production capacity [2][11][21] 10. **Future Product Plans**: There are ongoing validations for new products like CW, with potential surprises from the Yuyuan team. The company is also investing in new fields such as sensing and lidar [2][25] Additional Important Information - **Customer Base**: The silicon photonics high-temperature FAU product line is in small batch supply, mainly for verification and design, with some customers starting bulk purchases [2][16] - **Acquisition Impact**: The acquisition of Foxima is expected to enhance collaboration in customer validation processes, although the company still relies on external sourcing for certain components [2][17] - **Market Trends**: The demand for DFB access networks is strong, with new applications in sensing and lidar being explored [2][24] - **Product Transition Signals**: There are no clear signals yet regarding the transition of 800 series and 1.6T products to new solutions, as internal and customer recognition processes take time [2][25]
