A detailed computer simulation of optical FSK and DPSK transmission systems is carried out with the direct detection receivers using Mach-Zehnder interferometer (MZI). The performance degradation of the systems due to the combined effect of the fiber chromatic dispersion and receiver noise is evaluated. The simulation results show that the DPSK system is less sensitive to fiber chromatic dispersion and for a dispersion penalty of 1 dB, the maximum allowable fiber length is around 80 km for FSK and 250 km for DPSK using a dispersion index of 0.05
