DWDM transmission
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. Seacent Photonics's Athermal AWG(AAWG) provide excellent optical performance, high reliability, ease of fiber handling and power saving solution in a compact package
