Huawei optical module viewing

You can view Huawei optical module information using the display transceiver and display interface commands to check module type, status, DDM data, and other parameters.Basic CommandsView all optical modules on a device Use the command: display transceiver This lists all optical ports and their modules, including type, connector, wavelength, transfer distance, and vendor information .View a specific optical module Use: display transceiver interface Replace and with the actual interface, e.g., GigabitEthernet 0/0/1. This shows detailed information for that port .View diagnostic (DDM) information To check real-time operating parameters such as temperature, voltage, bias current, and optical power, add the verbose parameter: display transceiver interface verbose This provides transmit/receive power, temperature, voltage, and current readings, which are essential for troubleshooting .Using Interface CommandsCheck interface status: display interface This shows link status (UP/DOWN), module type, interface rate, and traffic statistics, helping verify if the module is functioning correctly .List all interfaces briefly: display interface brief Useful if you are unsure of the interface number; it lists all interfaces and their status .Important ConsiderationsCertified modules: Huawei recommends using Huawei-certified optical modules to avoid installation issues, data bus errors, or interface damage caused by non-standard modules .Module types: You can determine whether a module is single-mode or multi-mode, its wavelength, and transmission distance using the above commands .Troubleshooting: DDM data helps identify low/high optical power, temperature anomalies, or voltage issues, which can indicate module faults or environmental problems . By combining display transceiver and display interface commands, you can comprehensively monitor and troubleshoot Huawei optical modules, ensuring proper operation and network reliability.
