Abstract
In this article combined effects of PDL and PMD are taken into consideration. These may be divided into two main groups: PDL affecting DGD probability density function and loss of orthogonality of principal polarization modes causing destructive interferences. The above mentioned problems are investigated through numerical simulations based on a cascade model of a fiber. It is shown that PDL may affect the system with PMD when it is spread around the fiber as well as if it is placed between fiber's sections in PDL only elements. Based on these two cases, plots describing evolution of DGD probability density function are shown. The problem of principal polarization modes orthogonality loss is investigated with the help of numerical simulations, too. The probability density function of orthogonality of two principal polarization modes is shown for different PDL. To summarize the problem, the plot of system malfunction time during a one-year period due to average PDL is provided.
