How to obtain the SN of Huawei optical modules

You can view the serial number of a Huawei optical module using the display transceiver command on the specific interface or slot.Commands to View Optical Module InformationFor a specific interface: Use the command:CodeCopydisplay transceiver interface verbose This command displays detailed information about the optical module, including the manufacturer, ordering name, manufacturing date, and serial number (SN) of the module .For all optical ports:CodeCopydisplay transceiver This lists the optical module information for all ports on the device, including the serial numbers .For diagnostic information:CodeCopydisplay transceiver diagnosis interface This command provides digital diagnostic monitoring (DDM) data, which may include temperature, voltage, bias current, and optical power, alongside the serial number .Example OutputWhen you run the command, you may see output similar to:CodeCopyVendor Name : HG GENUINEOrdering Name : Manu. Serial Number: MA09140180968Manufacturing Date: 2009-04-09Transceiver Type : 1000_BASE_LX_SFPConnector Type : LCWavelength(nm) : 1310Transfer Distance : 10000mDigital Diagnostic Monitoring : YES Here, the Manu. Serial Number field shows the optical module's SN .NotesEnsure you are using Huawei-certified optical modules, as non-certified modules may not display correct information .The verbose parameter is recommended to obtain full details, including serial number, temperature, voltage, and optical power.These commands are applicable to Huawei switches and routers, including the S5700, S6720, AR600, and AR6100 series . By using these commands, network administrators can efficiently retrieve the serial number and other key details of Huawei optical modules for inventory, troubleshooting, or verification purposes.
