Understanding WDM(Wavelength Division Multiplexing) Technologies
TFF(Thin-film filter) and AWG(Arrayed Waveguide Grating) are two main WDM technologies. How do they work? What''s the principle?
The AWG (arrayed-waveguide grating) multiplexer/demultiplexer combines and splits many channels (up to 88) of optical signals with different wavelengths useful in DWDM systems. The products feature both Gaussian and flat-top types that offer narrow channel spacing (100GHz or 50GHz). We produce fiber-coupled Wavelength-Division Multiplexing (WDM) devices that combine (Mux) or separate (DeMux) multiple wavelength channels into or from a single optical fiber. Close collaboration with our customers and our proven expertise across fiber, cable, and connectivity ensure you'll get solutions that are smarter, denser, faster, and easier. Wavelength division multiplexers are fundamental to the functio...

Dense wavelength-division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of EDFAs, which are effective for wavelengths between approximately 1525–1565 nm (C band), or 1570–1610 nm (L band). EDFAs were originally developed to replace SONET/SDH optical-electrical-optical (OEO) regenerators, which they have made pra
