AbstrcatThe transmission of optical signal under the effect of dispersion and nonlinearity is investigated by small signal analysis.Frequency domain transfer function (FDTF) is given which include loss,dispersion,self phase modulation (SPM) and cross phase modulation (XPM) and reflects XPM process.The analytical method to determine the time domain shape of probe wave when arbitrary pump wave is inputted is confirmed in intensity modulation direct detection system.We find that the SPM in pump channel increases FDTF to some extent and the increased extent is enhanced with the increase of modulation frequency,average power of input signal and transmission distance.The analytical result agrees well with numerical simulation.
