DWDM AAWG (Athermal Array Waveguide Grating) module is based on PLC (Planar Waveguide) technology and does not require additional power supply or temperature control. It is a pure passive module; compared to traditional TFF (Thin Film Filter) products, AAWG has the advantages of high integration, good uniformity, low PMD, low insertion loss, etc.
