Product FAQ

Frequently Asked Questions

Answers to common compatibility, installation and troubleshooting questions.

Why does my compatible transceiver keep losing and restoring the link?

Intermittent links can be caused by marginal optical power, dirty connectors, unstable fiber connections, FEC mismatches, port configuration, temperature, or compatibility issues. Check both the optical link and host-side configuration.

How can I tell whether the problem is compatibility-related or an optical-link problem?

Check whether the host correctly identifies the transceiver first. If the module is rejected, incorrectly identified, or generates vendor-related warnings, investigate compatibility. If it is correctly recognized but the link remains down, investigate fiber, optical power, wavelength, FEC, polarity, and the remote endpoint.

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.

Can OEM and compatible transceivers be used in the same switch?

In many networks, OEM and compatible transceivers are deployed in different ports of the same device. Each module should meet the requirements of its individual interface.

How can I verify compatibility before ordering?

Check the network-device manufacturer and model, port type, required data rate, OEM transceiver reference if available, wavelength, reach, connector, fiber type, and software or firmware version when relevant.
