A method for modulating fiber optic transmissions with a low sensitivity to fiber non-linearity utilizes short pulses (typically shorter than 20 ps), and bit rates of 10 Gb/s and higher, to improve performance relative to heretofore known nonlinear transmission with Return-to-Zero (RZ) format implementations. At a base bit rate of 40 Gb/s, a distance determination for achieving 100% cumulative dispersion compensation is made, and a predetermined amount of pre-dispersion compensation is applied based on a determined distance using lower duty cycles for transmission. Higher bit rates (i.e., higher than 40 Gb/s) broaden the spectral bandwidth of the transmission and can result in no pre-dispersion compensation or negative distance pre-dispersion compensation of the same sign as the transmission fiber.
