The article reviews existing approaches to network analysis, taking into account the topological properties of networks. A sequential analysis from a network link to the properties of a set of network links is carried out. The network link is analysed as a set of optical channels, and an analytical description of the transmission quality in such a channel is carried out. A model for calculating crosstalk in the paths of information and communication optical networks is proposed. As can be seen from the results, for an optical fibre of a given length, there is a number of steps for selecting the input polarisation ellipse for which the efficiency of the method is maximised. Also, with an increase in the number of steps, we observe a decrease in the efficiency of this compensation method. So, for an optical fibre of a given length at constant dynamics, there is a number of input signal polarisation ellipses for which the polarisation-mode dispersion will be minimal. For a particular fibre, this parameter (the number of input signals) must be selected, because this value is different for different fibres (within the range of 15-30 points).Downloads
