Couple equations have been used to evaluate the performance of the communication link. When the optical power is increased, a noticeable rise in crosstalk caused by XPM has been observed. Although 3OD, 4OD, and 5OD have less of an influence than 2OD, they nevertheless contribute when considered collectively. The crosstalk caused by XPM rises with the addition of 2OD, 3OD, 4OD, and 5OD parameters. The findings indicate that when optical power changes from 2 to 50 mW, the XPM-induced crosstalk levels are as follows: (-75.01 to − 31.04) dB, (− 140.1 to − 72.1) dB, (− 220.6 to − 147.3) dB, and (− 325 to − 231.7) dB for 2OD, 3OD, 4OD, and 5OD respectively. Additionally, when considering combined dispersion orders such as (2OD + 3OD), (3OD + 4OD), and (4OD + 5OD), the XPM-induced crosstalk values are (-99.89 to -70.7) dB, (-139.6 to -104.2) dB, and (-189.9 to -146.3) dB respectively. The XPM crosstalk for the combinations (2OD + 3OD + 4OD + 5OD) and (3OD + 4OD + 5OD) varies between (-104.9 to -79.8) dB and (-134.3 to -102.6) dB respectively.
