Test Plan & Case Development: Define functional, performance, and reliability test plans for high-speed optical devices (COC, TOSA, etc. at 100G/400G/800G, incoherent & coherent) or optical modules (SFP, SFP+, QSFP, QSFP28, OSFP, etc.); compile standardized test cases and procedures. 2. Test Execution & Data Recording: Set up standardized test environments; use optical power meters, BERT, oscilloscopes, spectrum analyzers, network analyzers, integrating spheres, couplers, wavelength meters, etc. to perform sample testing, mass-production sampling, and reliability verification (high/low-temperature cycling, damp-heat, vibration); accurately record data and generate reports. 3. Automated Test Development: Support the development, debugging, and evaluation of automated test software and hardware in the engineering phase; promote PC-based (LabVIEW/C#/Python) and scripted testing to improve efficiency and coverage. 4. Problem Localization & Feedback: Perform preliminary localization of functional anomalies, out-of-spec performance, and reliability failures; collaborate with R&D and production on root-cause analysis; track corrective actions and verify effectiveness. 5. Test Process Optimization: Review existing test processes, identify pain points, and propose improvements to enhance efficiency, accuracy, and coverage; participate in selection/debugging of test equipment, fixtures, and tools. 6. Work with product designers to evaluate, build, and implement reliability test plans (BDH, HTOL, ESD for optical devices; burn-in for modules); evaluate and verify supplier-provided customized fixtures, test and mass-production equipment, and continuously improve equipment performance. 7. Documentation & Standard Maintenance: Maintain industry standards (IEEE 802.3, OIF, MSA, Telcordia, IEC, etc.), company specs, and work instructions for testing; archive test data and reports for traceability; participate in PVT/NPI performance evaluation and reviews.
