IM/DD optical system performance in the presence of dispersion, timing jitter and Gaussian noise

The intensity modulation and direct detection (IM/DD) optical system is considered by treating the optical fiber as a linear medium. First, the conditions under which the dispersion effects dominate over the nonlinear effects are defined. The case of Gaussian pulse propagation is assumed. The error probability is calculated for unchirped and chirped incident pulses in the presence of dispersion, timing jitter and Gaussian noise. Also the detailed analysis of obtained results is performed.
