Selection / comparison
How to Select a PM WDM
Choose a PM WDM by wavelength pair, fiber, optical power and polarization requirements.
Use this page when the application is known but the component specification still needs to be narrowed before RFQ.
Selection logic
Wavelength pair
Start with the two wavelengths you need to combine or separate, for example 980/1064 or 980/1550.
Architecture
Decide whether a fused WDM or filter-based WDM better matches the available standard specification and application.
Power and fiber
Confirm CW power, PM Panda fiber or custom fiber, connector and package before quotation.
Quick comparison
| Question | What to confirm |
|---|---|
| Which wavelengths? | Pump / signal wavelength pair |
| PM required? | Extinction ratio and key alignment |
| Power level? | CW power + connector requirement |
