16~48CH DWDM Thermal Arrayed Waveguide Grating Module

DK Photonics Thermal AWG DWDM (Arrayed Waveguide Grating Dense Wavelength Division Mux/Demultiplexer) Modules are designed for use within the C- or L-band release of DWDM system.

DK Photonics Thermal AWG DWDM (Arrayed Waveguide Grating Dense Wavelength Division Mux/Demultiplexer) Modules are designed for use within the C- or L-band release of DWDM system. To decrease the power dissipation of the devices in different environmental conditions, the AWG package is special designed with selection of reliable thermal plastic with low thermal conduction, and the AWG operating temperature is controlled by using foil resist heater or Peltier TEC with thermistor temperature sensor.

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.

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. Custom frequency grids, fiber types and connectorisation options are also available.
