Standard vs High Power PM WDM

Compare standard PM WDM and high-power PM WDM options by power, wavelength pair, package and system application.

Use this page when

the wavelength pair is known but you need to determine whether a standard device has enough power handling.

Quick comparison

Selection pointStandard PM WDMHigh Power PM WDM
Product examplesPM Fused WDM: 3 W; Mini PM WDM: 500 mWHigh Power PM Fused WDM: 5/10/20 W
Package directionCompact / wavelength-pair dependent70 x 12 x 8 mm for high-power fused WDM
Primary useStandard amplifier, sensing, communicationsHigher-power laser/amplifier paths
Critical checkWavelength pair, ER, isolationPower + wavelength pair + fiber + thermal/package
RFQ rule: The fastest inquiry includes the application plus wavelength, power, fiber, connector and quantity. If one parameter is unknown, send the known conditions for engineering review.

Which one should you choose?

Choose Standard PM WDM when...

Choose the standard family when its specified power rating comfortably covers the system and smaller packaging is useful.

Choose High Power PM WDM when...

Choose the high-power family when CW power exceeds the standard device limit or the system explicitly requires a high-power package.

Common questions

Can a standard 3 W WDM be used at 5 W?

Do not assume this. Use the specified high-power series or request engineering confirmation.

Does a larger package automatically mean higher power?

No. Use the specified power rating and package together rather than package size alone.

Still not sure which configuration fits?

Send the application and known parameters. Engineering can confirm the remaining specification.
