With a typical supernova rate $R_{\\mathrm{SN}}(z)$ and supernova neutrino spectrum $\\mathrm{d} N(E_\\nu)/\\mathrm{d} E_\\nu$, the DSNB flux spectrum $n(E_\\nu)$ in three categories of CG models, the generalized CG (GCG), modified CG (MCG) and extended CG (ECG) models, are studied. It is found that generally the flux spectra take a form similar to a Fermi-Dirac distribution with a peak centered around 3.80-3.97 MeV.
