In this research, the effect of polarization dependent loss of signals entering fiber optic communication systems on the efficiency of the signals output through the model of wave carriers passing through single mode optical fibers was studied, taking into account the dispersion in the waves passing through the optical fiber caused by chromatic dispersion and the polarization pattern of the waves passing through the optical fiber according to the physical laws of fiber optic physics that work to show the signal coming out of the fiber optic communication system with a certain efficiency. This is done through our study of the effect of polarization loss (PDL) on the pulse error rate (BER) in fiber optic systems. In addition, the effect of polarization loss on the calculation of the pulse error rate (BER) of the outgoing signals was studied .It was found that with increasing polarization loss (PDL) and increasing polarization pattern dispersion (PMD), the pulse error rate (BER) increases, and the best value (BER) is when it is (PDL=0dB and PMD=2ps), and the effect of polarization loss on the quality factor (Factor-Q) was studied, and we found that with increasing polarization loss (PDL) and increasing polarization pattern dispersion (PMD), the quality factor (QFactor) decreases. In addition, the effect of polarization loss on the signal-to-noise ratio received in receivers (OSNR) was studied, and the study showed that with increasing polarization loss (PDL) and increasing polarization pattern dispersion (PMD), the optical signal to noise ratio (OSNR) decreased. The study showed that the best value (Q-Factor) and the pulse error rate as well as the optical signal ratio for noise when (PDL=0dB and (PMD=2ps). All calculations in this research were performed using MATLAB.
