FWDM,i.e. Filter Wavelength Division Multiplexing,widely used for triple-play integration network,FTTH etc.FWDM have three wavelengths 1310/1490/1550nm,three end ports-COM,Pass(pass one or two wavelengths of 1310/1490/1550nm),Reflect(reflect other wavelengths except for the pass wavelengths)
1)Low insertion loss
2)Broadband transmission
3)High isolation
4)High stability and reliability
1)Line monitoring
2)WDM system
3)Fiber optical amplifier
4)Triple-Play FTTH
