In this article, coupled equations are being used to evaluate XPM induced crosstalk in SCM–WDM–HAN communication link using millimeter waves. Millimeter waves are having very high frequency (of the order of THz) and short wavelength (of the order of millimeter). Information carrying capacity of a carrier wave is directly proportional to its frequency, therefore using millimeter waves as a carrier can meet the relentless demand of customers for higher and higher data speed but these millimeter waves are drastically attenuated by atmosphere therefore optical fibers as a transmission medium are being explored. These millimeter waves are being extensively explored for use in 5 G telecommunication network as carrier waves therefore an attempt has been made to deal with high frequency waves and it is concluded that XPM induced crosstalk increases with increase both in transmission length and modulation frequencies. We have achieved transmission length of 3.5 km with V band (40−75 GHz) and 2.5 km with W band (75−110 GHz) in SCM–WDM–HAN link using coupled equations. It is found that XPM crosstalk is -28.04, -22.48, -16.57, -12.51 and -9.51 dB at the transmission length of 1.5, 2, 2.5, 3 and 3.5 km at 75 GHz and XPM crosstalk is -20.2, -14.21, -9.56, -6.55 and -3.02 dB at the transmission length of .5, 1, 1.5, 2 and 2.5 km at 110 GHz.

在本文中，耦合方程式被用于评估毫米波在SCM–WDM–HAN通信链路中XPM引起的串扰。毫米波具有非常高的频率（大约为THz）和短波长（大约为毫米）。载波的信息承载能力与其频率成正比，因此使用毫米波作为载波可以满足客户对越来越高的数据速度的不懈需求，但是这些毫米波会被大气层极大地衰减，因此光纤作为传输介质正在探索中。这些毫米波正在被广泛地探索作为5 G电信网络中的载波使用，因此已经尝试处理高频波，并且得出的结论是XPM引起的串扰会随着传输长度和调制频率的增加而增加。使用耦合方程，在SCM–WDM–HAN链路中，V波段（40−75 GHz）的传输长度为3.5 km，W波段（75−110 GHz）的传输长度为2.5 km。发现在75 GHz的传输长度为1.5、2、2.5、3和3.5 km时，XPM串扰为-28.04，-22.48，-16.57，-12.51和-9.51 dB，XPM串扰为-20.2，-14.21，在110 GHz的0.5、1、1.5、2和2.5 km的传输长度上为-9.56，-6.55和-3.02 dB。使用耦合方程，在SCM–WDM–HAN链路中，V波段（40−75 GHz）5 km，W波段（75−110 GHz）2.5 km。发现在75 GHz的传输长度为1.5、2、2.5、3和3.5 km时，XPM串扰为-28.04，-22.48，-16.57，-12.51和-9.51 dB，XPM串扰为-20.2，-14.21，在110 GHz的0.5、1、1.5、2和2.5 km的传输长度上为-9.56，-6.55和-3.02 dB。使用耦合方程，在SCM–WDM–HAN链路中，V波段（40−75 GHz）5 km，W波段（75−110 GHz）2.5 km。发现在75 GHz的传输长度为1.5、2、2.5、3和3.5 km时，XPM串扰为-28.04，-22.48，-16.57，-12.51和-9.51 dB，XPM串扰为-20.2，-14.21，在110 GHz的0.5、1、1.5、2和2.5 km的传输长度上为-9.56，-6.55和-3.02 dB。
