HJY Wavelength Division Product Quality Control Strategies and Advantages
——Driving the Excellent Quality of Optical Communication Components through Technological Innovation
In the rapidly developing field of optical communication, HJY Company always aims for "zero defects" and ensures the reliability and high performance of wavelength division products (such as CWDM/DWDM MUX DEMUX, FWDM, AAWG, etc.) through a full - process quality control system. Our quality control strategies not only cover all aspects of design, production, and testing but also meet the high - standard requirements of global customers for core optical module components through a data - driven continuous improvement mechanism.
I. Full - process Quality Control System
Rigorous Verification in the Design Stage
Through simulation software and prototype testing, ensure that product designs comply with international standards (such as Telcordia GR - 1209/1221). For example, in the design of AAWG chips, a waveguide optimization algorithm is used to reduce the risks of insertion loss and crosstalk.
Introduce closed - loop management of customer requirements, directly integrating market feedback (such as temperature stability, channel consistency) into design iterations.
Raw Material and Supply Chain Management
Use wafers, optical fibers, and optical coating materials from global top - tier suppliers, establish a supplier classification evaluation system, and regularly review their quality certifications (such as ISO 9001).
Conduct spectral analysis, mechanical strength testing, etc. on all incoming raw materials to ensure batch stability.
Precision Manufacturing and Process Control
In the production process, automated mounting equipment and clean rooms (Class 1000) are adopted to reduce human errors.
Implement SPC (Statistical Process Control) for key processes (such as DWDM filter coating), and monitor parameters such as film thickness uniformity in real - time.
Multi - dimensional Testing and Certification
Laboratory - level testing: Use equipment such as OSA spectrum analyzers and high - low - temperature cycling chambers to verify the performance stability of products at - 40°C to 85°C.
Third - party certification: Obtain reliability certifications from third - party institutions (such as TÜV, CE) to ensure the objectivity of data.
Customer Feedback and Continuous Improvement
Establish a 24 - hour response mechanism for global customer complaints, and locate the root causes of problems through failure mode analysis (such as FMEA).
Regularly release quality white papers and disclose key indicators (such as mean time between failures > 100,000 hours).
II. Quality Control Achievements and Customer Value
Product Qualification Rate > 99.5%: Through SPC and automated testing, the defective product rate is controlled at an industry - leading level.
Improvement in Customer Satisfaction: In 2024, the return rate decreased by 30% year - on - year, and the customer repurchase rate reached 85%.
Fast Delivery Capability: Relying on the digital quality management system, full - process traceability from order to delivery is achieved, and the average delivery cycle is shortened by 20%.
