Wavelength Division Multiplexing (WDM)

Neptec’s high-power Wavelength Division Multiplexing (WDM) products are designed for a variety of high power applications. WDM combines and transmits multiple signals simultaneously using multiple wavelengths through the same fiber. In addition, Neptec’s high-power WDM’s offer laser systems the flexibility to operate at a variety of specific wavelengths.

As with all of Neptec’s products, Neptec’s high-power WDM’s can be custom designed and manufactured for any specific application. If the standard high-power WDM below does not fit your application, we would be glad to review your specifications and quote a custom WDM for you.
