A new kind of zero order dispersion with Hexagonal structure and triangular lattice photonic crystal fiber of different air-hole diameters in cladding region is projected and the dispersion is investigated employing a compact 3-D finite distinction frequency domain method with the anisotropic perfectly matched layers (PML) absorbing boundary conditions. The proposed result is through numerical simulation and optimizing the geometrical parameters like by changing the diameter of holes (d) for photonic crystal fibers in triangular lattice structure. After analyzing all the result, it has been demonstrated that it is possible to obtain zero dispersion at 1.55µm wavelength which lies in the wavelength range of 1.53 to 1.65 μm with low confinement losses from a six ring into which ring are designed as elliptic and circular. The best choice of material for the designing purpose is silica material, which has refractive index 1.458.
