The loss and dispersion of optical fiber are essential characteristics that should be identified in fiber optics design as optical transmission lines. To obtain acceptable Dispersion compensated fiber DCF, one way to achieve high negative dispersion is to modify the refractive index definition of DCF. In this paper, using the optifiber software, the zero dispersion wave length (ZDW) conversion is a transformer by changing the standard single-mode fiber S-SMF standard refractive index profile for single-mode fibers, and then promoting a profile designed to reduce dispersion, bending loss and splice loss. Performance analysis is done using two design of fiber profiles using finite difference method analysis. The achieved results, by compared the characteristics of the step-index with two ring profiles in two different designs analysis, it has been found that better results for dispersion and loss done by decreasing the width of the core and cladding region inside the fiber.
