    Abstract: The study describes the quality indicators (Ping and BER) of RS-485 and Ethernet traditional
interfaces, as well as advanced technology of xPON-networks used in the construction of the collection and
transmission systems in power industry. The technical and economic aspects of passive optical networks use
in power industry on the example of GPON networks are analyzed in this study. The study proposes the use
of well-known GPON technology for the systems of information collection and transmission, when solving the
problems of construction of centralized systems of relay protection, automation and signaling as well as the
organization of technological information collection from microprocessor units of relay protection,
mechanization and automation in electrical installations of different voltage classes.
