DWDM CWDM oadm 4ch fbt fiber optical coupler
1.Wavelength Division Multiplexers --WDM-1310/1550 (FBT):
The fused fiber single mode wavelength division multiplexers combine or separate light at two different wavelengths with high isolation and low insertion loss. These bi-directional WDM products have low polarization dependence. As the deferent isolation, there is three types, WDM(≥20dB), HWDM(≥38dB), SWDM(≥45dB). For the details please refer to them..
