Mini 48CH Athermal AWG Module can transmit photosynthetic waves of up to 48 wavelengths or decompose the combined light waves into independent light waves. It is widely used in dense wavelength division multiplexing system.
Athermal AWG (AAWG) has comparable performance to standard thermal AWG (TAWG), but does not require a power supply to stabilize. They can directly replace thin film filters (filter-type DWDM modules) in the absence of power, and are also suitable for outdoor applications exceeding -30 to +70 degrees in access networks. Different input and output fibers, such as SM fiber, MM fiber, and PM fiber, can be selected to meet different applications.
