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 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.

Will DOM values appear correctly on third-party transceivers?

With a properly compatible module and supported host platform, DOM/DDM values should normally be accessible through the network equipment's management interface.

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.

Can third-party transceivers damage a switch?

A properly designed transceiver that meets the required electrical, mechanical, thermal, and interface specifications should operate within the host platform's intended transceiver interface requirements.

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.
