In telecommunications a constant need for improved user experience is present. In response technologies are constantly being developed and upgraded. The development of optical access networks has represented a turning point, providing virtually unlimited possibilities for data transfer. The implementation of this technology is taking place gradually, mainly on economic grounds, through intermediate hybrid fiber/copper solutions. G.fast technology has emerged as a compromise solution which allows the continuation of the high transmission speed even when the signal from the optical fiber network passes to the copper. G.fast represents a digital subscriber line (DSL) standard for copper loop of less than 250 m on a transfer target of 150 Mbit/s and 1 Gbit/s. Currently the G.fast technology in the phase of first pilot implementations after standards approval and preliminary tests which confirmed the great potential and practical value of the technology. The thesis describes the main features and key technological features of G.fast underlining both the advantages as well as the technological challenges of the technology. It is followed by a discussion of the importance of G.fast in the telecommunications sector in Slovenia as well as aspects of implementation.
