How to view Huawei optical module configuration

Use the display transceiver commands on Huawei switches to view optical module information, including identification, diagnostic data, and real-time operational parameters.

Viewing Optical Module Information

Display all optical modules on the switch Run the command: CodeCopydisplay transceiver This shows a summary of all optical ports, including transceiver type, connector type, wavelength, transfer distance, and vendor information. Display a specific optical module on a port Use the command: CodeCopydisplay transceiver interface Replace and with the port type and ID. This provides detailed information for the selected port.

View detailed diagnostic data Add the verbose parameter to see real-time Digital Diagnostic Monitoring (DDM) values: CodeCopydisplay transceiver interface verbose This output includes: Transceiver identity: model, wavelength, transmission distance, serial number, manufacturer, and manufacturing dateReal-time DDM values: TX/RX optical power, temperature, voltage, and bias currentAlarm thresholds for each parameter to detect abnormal conditions Run diagnostic checks For additional diagnostics, some Huawei switches support: CodeCopydisplay transceiver diagnosis interface This command provides fault analysis and detailed monitoring of the optical module.

Best Practices

Use Huawei-certified optical modules to ensure accurate information and compatibility. Non-certified modules may not report correct data or may fail to install. Monitor alarms such as abnormal transmit/receive power, temperature, or voltage to maintain network stability.

Check module type (single-mode or multi-mode) and transmission distance to match network requirements. By following these commands, you can comprehensively view the configuration, operational status, and diagnostic information of Huawei optical modules on your switches.
