Abstract
In this paper, the XPM-induced crosstalk has been evaluated with combined effect of second order Dispersion (2OD) and third order Dispersion (3OD) in SCM–WDM optical transmission link for varied dispersion parameters in different modulation frequencies and transmission lengths. It has been observed that there is significant effect of 2OD and 3OD on the XPM-induced crosstalk in a SCM–WDM transmission link. It has been observed that XPM-induced crosstalk lies between (−54 to −30) to (−42 to −18) dB and (−54 to −28) to (−38 to 16) dB in the presence of combined effect of 2OD and 3OD respectively for dispersion varied from 5ps/nm/km to 20ps/nm/km. Hence it observed that there is exponent increase in XPM-induced crosstalk with the increase in different modulation frequencies and transmission lengths and as dispersion increases, XPM-induced crosstalk also increases.
