WebUnderstanding DWDM ITU Channel. The standard ITU-T G.694.1 restricts DWDM (Dense Wavelength Division Multiplexing) operation wavelengths between 1528.77 nm to 1560.61 nm, which mainly corresponds to the C band. The CWDM ITU channel spacing is 100 GHz (0.8nm) for 40 channels. O-Band: 1270nm to 1370nm E-Band: 1371nm to 1470nm S … WebDWDM signals within the 1550nm band which are wavelengths between approximately 1530–1565nm (C band) and/or 1570–1625nm (L band) adhering to the DWDM ITU-T G.694.1 frequency grid.
