Annotation: The aim of the study is to analyze the approaches to signal separation and restoration in telecommunication systems on the example of fiber-optic information transmission systems and to justify the most optimal methods that will increase the capacity of communication lines. In the process of research the methods of separation and restoration of signals, which are used in the construction of multi-channel telecommunications systems are considered and their capabilities and features of use are highlighted. Particular attention is paid to the temporal separation of signals and separation of signals by wavelength. Also features and specificity of Rake-receivers are highlighted. In order to increase the capacity of existing and projected communication lines, it is advisable to combine the principles of temporal separation of signals and wavelength separation, which can be achieved based on a passive optical network. The article reveals the features and capabilities of the passive optical network in the context of increasing the speed of information transfer and elimination of the phenomena of polarization and chromatic dispersion. The capabilities of Rake receivers in terms of minimizing the effect of inter-character interference are also formulated.
