DWDM Thermal AWG Module
Description
DWDM Thermal Arrayed Waveguide Grating Module
F-tone’s Dense Wavelength Division Mux/Demultiplexer Thermal Arrayed Waveguide Grating 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. 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 connector options are also available.
Key Features
- High stability and reliability
- Low Insertion Loss
- Low PDL
- High Channel Isolation
- Multi-channel number
Applications
- WDM transmission
- WDM based ADM
- Metro and long haul net works
- Wavelength selective routing
