Starting this month, EB-LINK has upgraded the factory inspection process for optical modules that have completed customized coding. The modules must pass readback verification, optical port testing and actual plug-in inspection in order before they can be labeled and shipped, focusing on preventing the hidden dangers of mixed codes in multi-brand mixed order scenarios.
The first step: read back the coding fields one by one
After each module is programmed, the fixture will automatically read back the chip identification area and alarm area byte by byte, and compare it with the target code template. If there is any inconsistency, it will be returned to reburning, preventing half-written modules from flowing into the next process.
Mixed code problems often occur between adjacent boxes with the same appearance and different code types. The readback process changes manual verification from random inspection to 100%.
The second step: Optical port test plus random inspection and actual insertion
- Measure DDM readings of luminous power, temperature and voltage on the test platform one by one, and eliminate abnormalities;
- Sampling according to the code pattern and plugging it into the switch of the same model of the target brand, confirm that the recognition is normal and there are no alarm lines in the log;
- The label content and actual measured values are reviewed by a second person to prevent mislabeling when multiple code types are adjacent to each other.
What does inspection upgrade bring to procurement?
In a multi-brand network, once modules with the same appearance and different code types are connected to the wrong port, they are often exposed until the night of cutover. After the inspection process is upgraded, the correctness of the distribution depends on the process rather than manual memory. The coding test correspondence table accompanying the goods also provides a basis for subsequent operation and maintenance.SFP Gigabit single mode dual fiber 10KM optical moduleThe new process is also implemented for high-frequency spot models. The target brand code pattern and actual measured values are printed on the label. During subsequent inspections of operation and maintenance, the initial reading of the label is compared with the on-site value to distinguish whether it is module degradation or a change in the link environment.
The new inspection process covers all customized coding orders. If you need to request a test sample or arrange batch coding, please call 0755-83179002.
