Frequently Asked Questions

Answers to common compatibility, installation and troubleshooting questions.

Does the OEM part number need to match exactly?

The exact OEM reference is useful for identifying compatibility, but the optical specifications and host-platform requirements must also match the intended application.

How should I troubleshoot a compatible transceiver that is not recognized?

Confirm the module part number and compatibility profile, reseat the module, inspect the port status, check device logs, verify the operating-system version, and compare the module information reported by the host.

What happens if a transceiver has the wrong compatibility coding?

The device may reject the module, display an unsupported-transceiver warning, fail to establish a link, or provide incomplete monitoring information.

Can compatible transceivers be used with existing fiber cabling?

Yes, provided the module's fiber requirements match the installed cabling, including single-mode or multimode fiber, connector type, wavelength, and supported transmission distance.

Why does my switch detect the transceiver but not establish a link?

Possible causes include incorrect fiber type, wavelength mismatch, polarity, dirty connectors, excessive optical loss, incompatible link partners, FEC settings, port configuration, or compatibility issues.
