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. Flyin’s Athermal AWG(AAWG) provide 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. We can also offer different product packages, inluding special metal box and 19” 1U rackmount.
The planar DWDM components(Thermal/Athermal AWG) from Flyin Optronics are fully qualified according to Telcordia reliability assurance requirements for fiber optic and opto-electronic components (GR-1221-CORE/UNC, Generic Reliability Assurance Requirements for Fiber Optic Branching Components, and Telcordia TR-NWT-000468, Reliability Assurance Practices for Opto-electronic Devices).
