PON-FTTX Architecture and Bandwidth Analysis for Future Broadband Communications

Huge traffic and high bandwidth requirement of 5G and beyond networks call for holistic planning to establish seamless and cost-efficient transmission. Current and future passive optical networks (PON) will undoubtedly play an active role in actualizing a high-speed and cost-efficient networks through integration with 5G radio access networks (RAN) architecture. In doing this, fast speed modulation at each connection in the 5G xhaul architectures is required to cope with the strict latency and bandwidth requirements at each section. In this chapter, PON evolution up to the current and future PONs is reviewed to study different modulation approaches, their limitations, and complexities. We further reviewed different PON architectures and proposed usage possibilities for 5G and beyond networks.
