QUALITY IMPROVEMENT POLICY
  • Output Power Testing ensures that the module's transmission power is within specified limits for reliable signal transmission; Receiver Sensitivity Testing confirms that the module accurately receives signals at the required power levels, meeting industry standards; Extinction Ratio Assessment evaluates the clarity of the module's modulation signal to ensure effective data transmission and reception.
  • Compatibility testing encompasses switch, router, optical fiber, and network environment evaluations. We ensure module interoperability with different switch brands, seamless operation with various router models, compatibility with multiple fiber types, and stability across diverse network environments, ensuring reliability in long-distance and high-interference scenarios.
  • Test raw materials to ensure all incoming materials meet quality standards. Inspect semi-finished products at various stages to maintain quality. Maintain equipment by regularly servicing and calibrating it for accurate operation. Test finished products to ensure they meet all specifications and quality standards. Track production records to record and monitor production data to quickly address any issues.


  • Fiber Type Testing evaluates the optical module's adaptability to different fiber types (single-mode and multi-mode) for stability in various environments; Temperature Adaptability Testing assesses the optical module's performance under extreme temperatures to ensure reliability in diverse settings; Long-Distance Transmission Testing tests the optical module's signal stability over extended distances.


  • Supported Data Rate Range: Assess the optical module's range of supported data transmission rates from low to high speeds. Data Transmission Stability Testing: Evaluate signal stability across various data rates to ensure reliability. Rate Switching Testing: Assess the module's performance in switching between data rates for real-world applications.

  • Cleaning Inspection: Ensure the optical module's surface is clean for performance and appearance maintenance. Finished Product Testing: includes visual inspection, functional testing, and specification verification to ensure compliance with quality standards. Packaging Inspection: Check packaging integrity for adequate protection during transportation.
