Product selectionHow can I identify the correct form factor?

Check the device manual and the marking on the existing module or cable. SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP-DD and OSFP are not interchangeable merely because their connectors look similar.

Compatibility & codingWill DOM or DDM readings be available on the host?

They are available only when the module, interface and host software support the diagnostic functions and expose them correctly. Confirm the required readings as part of the device review.

Optical link designCan temperature influence optical margin?

Optical output, receiver performance and fibre or connector conditions can vary with environment. Use the specified operating range and retain reasonable link margin for the deployment.

Use the selection guide
High-speed deploymentHow do I choose between parallel and duplex high-speed optics?

Compare the host-supported standards, installed fibre, connector, reach and migration plan. Parallel optics often use MPO/MTP; duplex solutions use LC but may have different optical and FEC requirements.

Plan a technical review
Documents & procurementHow do I make sure a document applies to my exact model?

Compare the model reference, interface, reach and variant with your product shortlist. If the document is not published or the revision is unclear, send the model and required document type through the document request form before using it for approval.
