Where to find the optical module model

You can find the optical module model by checking the module label, using network device commands, or consulting manufacturer resources.

Physical Inspection

Most optical modules, such as SFP, SFP+, XFP, or QSFP modules, have a label on the module itself that displays the model number, vendor, and key specifications like bit rate and wavelength. The label is typically located on the top or side of the module and may include a barcode or serial number. Inspecting the label is the simplest way to identify the module model.

Using Network Device Commands

If the optical module is installed in a network device like a Cisco switch, you can query the module information via the device's command-line interface (CLI). For Cisco devices: Connect to the switch and log in with appropriate credentials. Enter privileged exec mode.

Use commands such as show interface [interface ID] transceiver or show fiber optic port media converter [interface ID] to display the module type, vendor, and diagnostic data. These commands provide details including the module model, supported speeds, and compatibility information.

Manufacturer and Vendor Resources

Manufacturers like TI, Cisco, and ETU-LINK provide online resources to identify and verify optical modules.

T

I offers reference designs and product recommendations for various module types. Cisco provides a catalog of optics and compatibility guides to ensure the module fits your network platform. ETU-LINK also offers modules pre-tested for Cisco compatibility and instructions for checking module information.

Summary

To find the optical module model: Check the physical label on the module for model and vendor information.

Use CL

I commands on the network device to query module details. Consult manufacturer resources for specifications, compatibility, and reference designs. By combining these methods, you can accurately identify the optical module model and ensure proper deployment or replacement.
