Abstract
A simple approximate analytical expression is derived for the intensity-modulation index in a phase-shift-keying coherent optical transmission system, accounting for both group-velocity dispersion and higher-order dispersion. This provides an analytical generalization of previously presented numerical results obtained in the limits of pure group-velocity dispersion and higher-order dispersion, respectively. The subsequently derived maximum transmission distance for 50% intensity modulation is found to be long at the zero-dispersion wavelength. However, for high modulation frequencies, the maximum transmission distance decreases rapidly when the wavelength deviates from the zero-dispersion wavelength. Comparisons with previously obtained numerical solutions show good agreement.
