Performance evaluation of SCM-WDM-HAN communication link using millimeter waves in the presence of XPM

摘要

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.
