Effectiveness of optical fiber networks in fifth and next generations of mobile systems

摘要

The paper presents methods for combining single and multi-channel fiber-optic links. On this basis, the architecture ofthe current and next generations of mobile communication systems, which should be strongly supported by all-opticalnetworks, is presented. An example of a mobile system based on the EON/OTN/TSON backbone and edge opticalnetworks operating in active and passive modes is presented. The current and future needs of mobile systems andnetworks were analyzed in terms of the quality of service parameters. Requirements for optical links used in separatenetworks of mobile systems such as NGC, BH, FH, and MH are presented. Calculations of the optical spectral efficiencyof single-channel optical links used in the mobile systems were made. The calculations include the coherent modulationsof single-carrier and multi-carrier OFDM formats, as well as D-RoF and A-RoF formats used in optical FH and MH. Theresults of the calculations are presented in diagrams. Application scenarios of the proposed network architecture andspectral effective modulation formats were discussed.
