“…The effect of XPM is given by the ratio of power bound to the optical fiber P and the effective surface of the optical fiber core A eff . Let's consider the N-channel DWDM system [5][6][7]. The phase shift of the i-th channel through the XPM effect is then as follows:…”

“…The first part of the equation 6represents the contribution of the SPM and the second part the contribution of the XPM. The second part of equation 6also expresses the nonlinear sensitivity, and indicates that XPM is two times more efficient at the same energy than the SPM [6][7][8][9].…”

The exponential increase in transmission capacity triggered the era of fast and reliable data transfer techniques through fiber optic networks. This has led to the exploration of new options in the field of spectrally efficient systems suitable for extremely high data rates. Consequently, there is a gradual transition from existing systems with a 10 Gbps transmission rate to 40 Gbps optical systems and even up to 100 Gbps. However, with the increase in network transmission capacity, the optical signal performance requirement is also increased to ensure acceptable bit error rate (BER) in the receiver. However, increasing transmission power leads to a distortion of the transmitted signal due to the nonlinear Kerr effects or interference between adjacent channels. These are the main limitations that set the upper limit of the maximum effective SNR (Signal-to-Noise Ratio) of the optical link and limit the performance of the whole system. On the other hand, linear effects such as chromatic dispersion (CD), optical SNR (OSNR), spontaneous photon emission, optical fiber loss, or channel overlapping through long stretches of optical fibers are also important factors that need to be considered when designing DWDM (Dense Wavelength Division Multiplexing) system.
