DK Photonics Athermal AWG DWDM (Arrayed Waveguide Grating Dense Wavelength Division Mux/Demultiplexer) Modules are part of a series of high performance products based on silica-on-silicon planar technology and a unique athermal packaging design requiring no electrical power, software or temperature control for a completely passive DWDM solution.
The arrayed waveguide grating (AWG) wavelength multi/demultiplexer combines and splits optical signals of different wavelengths for use in WDM systems. The heart of the device, the AWG, consists of a number of arrayed channel waveguides that act together like a diffraction grating in a spectrometer. The grating offers high wavelength resolution, thus attaining narrow wavelength channel spacings such as 0.8nm in ITU channel allocation. Moreover, the multiplexer’s extreme stability eliminates the negative effects caused by mechanical vibration; in addition, it delivers long-term reliability because it is composed of silica-based planar lightwave circuits. Athermal AWG DWDM offers a combination of very low loss and high channel isolation along with long term reliability.
We can offer different package for different products, inluding compact box package and 19″ 1U rackmount.Different input and output fibers, such as SM fibers, MM fibers and PM fiber can be selected to meet different applications.
