Path-averaged peak power considering dispersion effect

We derive the path-averaged peak power considering dispersion effect of optical fiber for the first time in our knowledge, in order to attain the results of the theoretical analysis of optical fiber transmission more accurately than the conventional path-averaged power which considers only the fiber attenuation. The ultimate accuracy of the newly developed path-averaged peak power is verified by computer simulations based on the transmission of differential phase-shift keying signal with data rates of 5 Gbps and 40 Gbps, in both transmission systems using the dispersion management and the optical phase conjugation. The numerical simulation results are in better agreement with the frequency response analysis of the phase error using the path-averaged peak power considering dispersion effect comparing to the phase error analysis obtained by using the conventional path-averaged peak power that considers only the fiber attenuation.
