AAWG
Athermal Arrayed Waveguide Grating
■Product Description
AAWG：Athermal Arrayed-Waveguide Grating mainly is used in DWDM system. It transmits signal by making different ITU-T DWDM wavelength signals multiplex to single fiber in receiving terminal. It decomposes composite signal into different ITU-T DWDM wavelength signal. The product has a low insertion loss, high channel insertion loss consistency, nothing external power supply and so on.
■Product features
♦ Low insertion loss
♦ High consistency channelinsertion loss
♦ Low polarization dependent loss
♦ High channel isolation
♦ Without power supply
♦ Excellent environmentalreliability
♦ High level of integration by plug-in design
