This article proposes a method for improving energy efficiency by reducing the peak power of the emitted signal in systems with DFT-s-OFDM for fiber-optic segments of future mobile networks of the 5G and 6G generation, based on the use of an improved "raised cosine" shaping filter, as well as ZT-DFT-s-OFDM technology for improved energy efficiency. Various new waveforms and modulation schemes are presented that would be both energetically and spectrally efficient. The analysis of the ratio of the peak signal power level to the average level for signals with DFT-s-OFDM in its various modifications in radio-optic networks is presented, various technologies for the formation of DFT-s-OFDM are analyzed depending on the method of access to the subscriber, such as DFDMA, LFDMA and IFDMA, considering the bandwidth extension factor.
