Five answers for this product path.
Product selectionHow do I choose between a transceiver, DAC and AOC?
Start with the host port, data rate and distance. A transceiver with a separate fibre lead gives the most flexibility; DAC suits the shortest in-rack copper links; AOC suits longer inter-rack links where a light integrated cable is useful.
Browse productsCompatibility & 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.
Start a model reviewOptical 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 guideHigh-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 reviewDocuments & 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.
