Product Compatibility Mapping

Cross-reference the original manufacturer part number with the corresponding Fiberland part number before confirming the target device and firmware.

A part-number cross-reference is a model-selection starting point, not a blanket device guarantee. Final fit depends on the exact device, firmware or OS, target port and requested coding profile.

Frequently Asked Questions

Answers to common compatibility, installation and troubleshooting questions.

Why does the link work at one end but show an error at the other end?

Each transceiver must be compatible with its own host device. In a mixed-vendor link, one end may be correctly coded while the transceiver at the opposite end is not fully compatible with its switch or router.

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.

Is the optical power of a compatible transceiver different from the OEM version?

A compatible replacement should meet the applicable transmit-power and receiver-sensitivity specifications for the interface it is designed to support.

Why does my switch show an “unsupported transceiver” warning?

Some network devices validate vendor information stored in the transceiver EEPROM. If the module's coding is not recognized by the host platform, the switch may display an unsupported or non-certified transceiver warning.

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.
