In this article, the tensile force impact on mode field diameter (MFD) of a 125µm modern multilayer WII type single mode optical fiber is investigated. The simulation results admit the growth of MFD while the applied tensile force increases. Among the structural parameters of the fiber, the MFD variation due to tensile force shows the most sensitiveness to changes in Δ and the least to R1. Moreover, in the design procedure for the maximum sensitivity of MFD to force, the management and determination of the optical and geometrical parameters of the fiber, for the optimum function, is accomplished by the means of genetic algorithm (GA). The outcome achieved through GA is almost 10 times better than the best result attained without optimization tool.
