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.

Product FAQ

Frequently Asked Questions

Answers to common compatibility, installation and troubleshooting questions.

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 my compatible transceiver show low RX optical power?

Low receive power can result from excessive fiber loss, dirty connectors, damaged fiber, excessive link distance, incorrect wavelength pairing, or insufficient transmit power from the remote transceiver. Compare the measured RX power with the module's specified receiver range.

How do I find a compatible transceiver for an OEM part number?

Search using the OEM part number and verify the form factor, data rate, wavelength, transmission distance, connector, fiber type, and host-platform compatibility.

Can compatible transceivers be reprogrammed?

Absolutely! All of our transceivers can be easily reprogrammed using our standalone offline coding kit. To get started, please share the part number, description, and serial number of your current transceivers, as well as the brands you need them to work with. Our team will generate the corresponding .bin file and send it over with clear instructions so you can update your transceivers immediately.

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.
