We offer a full range of AWG products, including 50GHz, 100GHz and 200GHz AWG. Here we present the generic specification for the 40-channel 100GHz AWG MUX/DEMUX component supplied for use in DWDM system.

 

This component is 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. Different input and output fibers, such as SM fibers, MM fibers and PM fiber can be selected to meet different applications. We can also offer different package for different products, inluding ABS box and 19” 1U rackmount.
