Athermal AWG(AAWG) have equivalent performance to standard Thermal AWG(TAWG) but require no electrical power for stabilization. They can be used as direct replacements for Thin Film Filters(Filter type DWDM module) for cases where no power is available, also suitable for outdoor applications over -30 to +70 degree in access networks
Features
High isolation
Excellent wavelength stability
High durability
DWDM wavelengths up to 48
5V power driving
Application
DWDM
Metro networks
