Selection Guides

Choose The Right Component Faster.

Use these guides when the application is clear but the exact component, power class, wavelength, fiber type or architecture still needs to be narrowed down.

Where this fitsApplications show where components are used. Products show what is available. Selection Guides help compare the choices between them before you open the datasheet or send an RFQ.
01 · Start hereYou know the applicationUse Applications first to identify the likely component family.
02 · Use a guideYou are comparing optionsCompare wavelength, power, fiber, topology or package choices.
03 · ConfirmYou have a target specificationOpen the datasheet, then use Engineering or RFQ for final confirmation.

How to use

Selection Guides do not replace the datasheet.

Their job is to narrow the choice. Final wavelength, power, fiber, connector and package should still be confirmed from the product data or engineering review.

01

Compare

Use the guide when two or more component families or specifications appear possible.

02

Check the product

Open the linked product page and datasheet to confirm the listed technical parameters.

03

Confirm the gaps

If one parameter remains unclear, send the known conditions for engineering review before quotation.

Already know the target specification?

You do not need to read every guide. Search the datasheets or send wavelength, power, fiber, connector, quantity and application directly for review.
