48CH Aawg, 100g DWDM Athermal AWG Module for DWDM Networks

48CH 100GHz AAWG DWDM Module Standard Metal Box Description: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.Features:MUX/DEMUX FunctionalityCompact PackageMulti-channel NumberAthermal Design, Electrical Power is Not RequiredLow Insertion Loss,Low PDL,High Channel IsolationApplications:PON NetworksDWDM TransmissionMetro Area NetworksLong-haul NetworksBuilding Blocks for ROADMBuilding Blocks for VMUX Specifications:ParametersAAWG DWDM MUX/DEMUXChannel Space (GHz)50GHz100GHzPass Band TypeFlat-topGaussianFlat-topCentral WavelengthITU-T GridGradeTypMinTypMinTypMinChannel Number80/9632/40/48Wavelength Accuracy (nm)±0.04±0.05Pass Band @1dB (nm)>0.2>0.2>0.4Pass Band @3dB (nm)>0.4>0.4>0.6Insertion Loss (dB)21Return Loss (dB)>40Ripple (dB)
