We got the simple and high accurate eigenvalue equations and cutoff frequency formulae of all propagation modes. Second, to the optical fiber with homogeneous cladding, we defined the "permittivity ratio", and we got the simple and high accurate connection of cutoff frequency to the ratio. Third, to the fiber with inhomogeneous cladding, we analyzed the dispersive and power-frequency characteristics.
