I would like to share the following information with all of you. I think it's interesting:

C-band 80-wavelength systems consist of even and odd wavelengths. Information about even and odd wavelengths is provided below:

C_EVEN: indicates even-numbered wavelengths. In total there are 40 even wavelengths. The center frequency of the even wavelengths is within the range of 192.100 THz to 196.000 THz (the center wavelength is within the range of 1529.55 nm to 1560.61 nm) and the frequency spacing is 100 GHz.
C_ODD: indicates odd-numbered wavelengths. In total there are 40 odd wavelengths. The center frequency of the odd wavelengths is within the range of 192.150 THz to 196.050 THz (the center wavelength is within the range of 1529.16 nm to 1560.20 nm) and the frequency spacing is 100 GHz.

Extended C-band 96-wavelength systems consist of even and odd wavelengths. The information about even and odd wavelengths is provided below:

Extended C_EVEN: indicates even-numbered wavelengths. In total there are 48 even wavelengths. The center frequency of the even wavelengths is within the range of 191.300 THz to 196.000 THz (center wavelength is within the range of 1529.55 nm to 1567.13 nm) and the frequency spacing is 100 GHz.
Extended C_ODD: indicates odd-numbered wavelengths. In total there are 48 odd wavelengths. The center frequency of the odd wavelengths is within the range of 191.350 THz to 196.050 THz (center wavelength is within the range of 1529.16 nm to 1566.72 nm) and the frequency spacing is 100 GHz.

Super C-band 120-wavelength systems consist of even and odd wavelengths. The information about even and odd wavelengths is provided below:

Extended C_EVEN: indicates even-numbered wavelengths. In total there are 60 even wavelengths. The center frequency of the even wavelengths is within the range of 190.750 THz to 196.650 THz (center wavelength is within the range of 1524.50 nm to 1571.65 nm) and the frequency spacing is 100 GHz.
Extended C_ODD: indicates odd-numbered wavelengths. In total there are 60 odd wavelengths. The center frequency of the odd wavelengths is within the range of 190.700 THz to 196.600 THz (center wavelength is within the range of 1524.89 nm to 1572.06 nm) and the frequency spacing is 100 GHz.
