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 of the current and next generations of mobile communication systems, which should be strongly supported by all-optical networks, is presented. An example of a mobile system based on the EON/OTN/TSON backbone and edge optical networks operating in active and passive modes is presented. The current and future needs of mobile systems and networks were analyzed in terms of the quality of service parameters. Requirements for optical links used in separate networks of mobile systems such as NGC, BH, FH, and MH are presented. Calculations of the optical spectral efficiency of single-channel optical links used in the mobile systems were made. The calculations include the coherent modulations of single-carrier and multi-carrier OFDM formats, as well as D-RoF and A-RoF formats used in optical FH and MH. The results of the calculations are presented in diagrams. Application scenarios of the proposed network architecture and spectral effective modulation formats were discussed.
