C Band ITU EDFA DWDM DCM WDM Solution OADM Module Long Haul Transfer Design
The DWDM passive OADM modules are protocol-transparent and invisible to both the network and the users, each DWDM passive OADM uses wavelengths that fall within the ITU-T G.694.2 DWDM grid standard from C17 to C61(1563.86~1528.77nm) with 0.8 nm spacing.
