## 4 Experimental Analysis and Discussion  
This proposed model is analyzed analytically in Section 3, which describes that NLIs and PAPRIs create discontinuity in the transmission signals. Furthermore, current CNs face high capacity demands, the number of channels, data rates, and long transmission path. The full-duplex RoF-based CN is analyzed in this model to minimize the order of NLIs and PAPRIs. The simulation results are investigated in this section based on block description and analytical models. The performance analysis of received power and BER, 1 to 10 km of transmission length, and 4 to 6 GHz RF range are presented in Figure 3. At \(-35\) dBm received power, the outcomes are achieved above the threshold range. The order of NLIs and PAPRIs are enhanced with transmission range and the frequency of RF waves. Below \(10^{-4}\) and \(10^{-5}\) BERs are achieved at \(-20\) dBm received Power 10 km length for 6 GHz and 4 GHz RF waves, respectively. Thus, there is a 0.1 BER difference between 6 and 4 GHz RF transmission. The phase errors (PEs) are induced in the transmission pulses by reason of NLIs and PAPRIs, which impact is declared in for different 0, 2.5, 5, and 8 deg PEs in terms of normalized signal to noise ratio and BER, with increasing PEs, the WDM-RoF presents the worst results. The simulation results in Figure 4 are investigated for RF 4 GHz, and length 5 km, the maximum 8 deg PE attains the threshold early than 0, 2, and 2.5 deg PEs. The analysis of the normalized signal to noise ratio as a function of BER at 5 km and 6 GHz RF waves is shown in Figure 5. This describes that with increasing the frequency of RF waves, the outcomes become worse as compared to Figure 4 which presents the outcomes of the presented model at 5 km and 4 GHz RF range. Similarly, Figures 6 and 7 contain the results of the presented model of 4 GHz and 6 GHz RF range at 10 km transmission length. It is depicted from the results that the PEs factors disturb system fidelity. It is recorded that till six normalized signals to noise ratio, the outcomes of the full-duplex system are above the threshold BER. With increasing the PE till 8 deg, then the proposed model presents bad outcomes as shown in Figures 6 and 7. Greater than seven normalized signals to noise ratio, the factors of NLIs, and PAPRIs are compensated successfully as declared in Figures 6 and 7. The main mechanisms to evaluate the PAPRIs and NLIs are full-duplex RoF linked with WDM and the DCF with \(-20\), \(-30\), \(-35\), and \(-40\) ps/nm/km dispersion magnitudes. These mentioned DCF dispersion are studied and analyzed using 4 and 6 GHz RF waves and 5 to 10 km transmission range. Figure 8 explains the information among the transmission range and BER, for \(-20\), \(-30\), \(-35\), and \(-40\) ps/nm/km DCF dispersion values, operating at 4 GHz RF range, which clarify that the above 8 km of fiber length the influences of NLIs and PAPRIs produce BER in the limited range. Moreover, the achievements of the full-duplex WDM based RoF model at \(-40\) ps/nm/km DCF dispersion are efficient compared to \(-35\), \(-30\), and \(20\) ps/nm/km dispersion of DCF. Keeping DCF dispersion at \(-40\) ps/nm/km for 5 km fiber length and RF 4 GHz, \(2.2\times 10^{-7}\) BER is attained. On the other hand, the outcomes touch the threshold range by employing DCF with \(-35\), \(-30\), and \(-20\) dispersion with the above-covered path and RF values. Figure 9 defines the same results as discussedin Figure 8 with transmission range and BER parameters, however here, the capacity of RF signals increased to 6 GHz. This concludes that the capacity of transmitted data has valuable contributions towards NLIs and PAPRIs. Figure 10 depicts the behavior of NLIs and PAPRIs and the proposed full-duplex RoF model and the outcomes while compensating these factors. The simulation results on account of launch power and BER are shown in Figure 10 RoF model, which covers 5 km transmission length and 4 GHz RF capacity. The destructive analysis is presented when NLIs and PAPRIs are not balanced.
