Single Mode Wavelength Division Multiplexers --WDM-1310/1550
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.
