| Abstract | Wireless system operating at millimeter-wave frequencies has attracted much interest as a means of providing broadband access for future multimedia applications. Optical fiber backbone can effectively support the usage at high data rate with high capacity. The linear and nonlinear restriction of optical fiber is important to consider. It becomes a significant factor that limits the system performance. In WDM millimeter-wave fiber-radio network, the multichannel usage will cause the high power density in fiber and make the nonlinearities condition become important. Hence, to get the most effective system, Split-Step Fourier method has been used in order to analyze the linear and nonlinear problem of the optical communications. It is required to solve the nonlinear Schrodinger equation to understand various impairments occurring during signal transmission. However, it is not possible to solve it analytically when both the nonlinearity and the dispersion effect. Therefore, numerous numerical algorithms have been developed. The split-step Fourier method is one of these, which provides the accurate and relatively results and requires less computation time and resources than other numerical algorithms. Moreover, it is flexible in term of using the step-size value to get the required result. Hence, this method is the most appropriate for this study. It has been applied to a wide variety of optical problems and provides the most accurate with short computing lead time. The results from simulation shows receive optical power and pulse propagation of single-mode fiber. It can also simulate the case to study the propagation properties in various conditions of single-mode fiber. Moreover, it can be used as a system simulation model which is compatible with other models as well. The study will benefit to the various effective single-mode optical fiber system designs. |
