DWDM full name Dense Wavelength Division Multiplexer,general wavelength is C band 100G DWDM Channel 14-Channel 61,there’re O band DWDM too but few.O band DWDM is for 5G or other special network.DWDM have two manufacturing teachnology,one is TFF(Thin Film Filter),another is arrayed waveguide grating(i.e. AWG).
1)Low insertion loss
2)Broadband transmission
3)High isolation
4)High stability and reliability
1)Metro network
2)WDM system
3)Fiber optical amplifier
4)5G backbone and fronthual

Notes:Above insertion loss is for Double Fiber w/o Mon(16Ch with skip filter),Single Fiber 2Ch≤1.5dB,4Ch≤2.5dB,8Ch≤3.0dB(8Ch with skip filter),with 1% Mon add 0.3dB,with 1310 port(bandwidth 1260~1360nm) add 0.3dB,with 1% Mon and 1310 port add 0.6dB.Double Fiber more than 16Ch and Single Fiber more than 8Ch suggest to use AWG.
