Five answers for this product path.
Product selectionShould I select an optic by its maximum reach?
Use the designed link length and loss budget, not maximum reach alone. Fibre type, connectors, patch panels, wavelength and receiver limits all affect whether a particular reach class is appropriate.
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 designDo both ends need the same wavelength?
Duplex links normally use matching interface wavelengths at both ends. BiDi and wavelength-division links use planned complementary or channel-specific wavelengths, so the exact link architecture matters.
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.
