Product Compatibility Mapping

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

Send the target device brand, model, firmware or OS and port details for an exact compatibility review.

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.

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.

Why does the switch detect the transceiver but report an incorrect module type?

This can occur when the EEPROM compatibility profile does not match the intended interface or when the host interprets the programmed identification differently. Verify the module coding and corresponding OEM reference.

Why does the switch report a vendor or part number different from the physical transceiver label?

Compatible transceivers may contain programmed identification information required by the host platform. The vendor or part number reported by the switch can therefore differ from the manufacturer's physical product label.

Why are the DDM/DOM readings incorrect or abnormal?

Abnormal temperature, voltage, TX power, RX power, or bias-current readings may indicate an optical or hardware issue, but they can also result from incorrect calibration or communication between the compatible module and host device.
