GEZHI AWG DWDM is by silica-on-silicon planar technology. The 40CH AWG Rackmount chips GEZHI Photonics used for DWDM Mux/Demux are targeted for Long-Haul, Metro and access applications, where outstanding optical performance and low cost are paramount.
Athermal Arrayed Waveguide Grating (AAWG) DWDM Modules features of athermal packaging design require no
electrical power, software or temperature control.
Thermal Arrayed Waveguide Grating (TAWG) DWDM Modules are designed for use within the C-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 channel spacing for DWDM is 1.6/0.8/0.4 nm (200GHz/100 GHz/50
GHz grid). This small channel spacing allows to transmit
simultaneously much more information
