| 英文摘要: |
| The internal hardware and software of coherent optical transceivers are relatively complicated, and it is hard to carry out a
large-scale test with the conventional manual method. The testing efficiency and productivity of coherent optical modules are also
seriously restricted. To this end, an automated test system for 400 and 800 Gb / s coherent optical modules is designed and implemented.
This system utilizes the programmable manipulation components to efficiently obtain the firmware, state sequence and optical parameters
of coherent transceivers. Moreover, an experimental test setup is built to verify the systemic effectiveness, in which multiple 400ZR and
400ZR+ modules from different vendors are evaluated. The test results show that compared to the manual method, the measuring time
can be lowered by nearly an order of magnitude with the proposed method, which significantly improves the testing efficiency. |
