Description
● Athermal AWG(AAWG):
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 degrees in access networks. Athermal AWG(AAWG) provides excellent optical performance, high reliability, ease of fiber handling and power saving solution in a compact package. Different input and output fibers, such as SM fibers, MM fibers, and PM fiber can be selected to meet different applications.
