Optical Module Serial Number

The serial number of an optical module can be found using device-specific CLI commands or by checking the physical label on the module.

Using CL

I Commands1. Huawei Devices: Run the command display elabel to view the electronic label of the optical module.

The Bar

Code field indicates the serial number. Alternatively, use display transceiver interface to see detailed information, including Manu. Serial Number and vendor details (e.g., JDSU, PLRXPLSCS4322N).

2. Cisco Devices: Use show interfaces transceiver or show interface to display module details. For more detailed information, including the serial number, run show idprom interface or show inventory to list all optical modules and their serial numbers.

3. Fortinet Devices: Use get system interface transceiver for all interfaces or get system interface transceiver for a specific interface. The output includes Vendor Name and Serial No., which identifies the optical module.

4. Linux Systems (RHEL): Use the ethtool -m command to query SFP module details. The output provides vendor information, part number, and serial number for the module.

Physical Inspection

Many optical modules have a label attached to the module itself. The serial number is usually printed as BarCode or Serial No. on this label. This method is useful if CLI access is unavailable or for quick verification.

Summary

To find the serial number of an optical module: Check the physical label on the module. Use vendor-specific CLI commands to query the module electronically. Ensure you specify the correct interface type and number when using CLI commands to retrieve accurate information.

By following these methods, you can reliably identify the serial number for inventory, troubleshooting, or warranty purposes.
