Dearfriend！ Huawei's DWDM system uses the frequency spacing is 100 GHz(0.8nm) both on the C-band system and extended C-band system. 40/48 wavelengths for odd and even wavelengths. If both odd and even wavelengths are used, the wavelength spacing is 50 GHz. As shown in the following figure:
When planning, you need to consider the single-fiber capacity, construction cost, and future scalability. Thanks! |
