With tolerable 6 µrad transmitter and 3 µrad receiver pointing error for both downstream and upstream direction, the designed FiWi link transmit the information successfully. The results show that the system can offer faithful −22 dBm received power and aggregate symmetric transmission rate of 16 × 25 Gbps over 50 km fiber reach with 10 km wireless range in the presence of losses and pointing errors of wired/wireless channel. Enhanced performances of quality factor, bit error rate (BER) and received power are observed for varying wireless range, data rate, additional losses, transmitter/receiver pointing errors and different weather conditions in the FiWi based hybrid TWDM/DWDM Super PON system. To extend the reach, transmission rate and number of subscribers passively, the fifth generation fiber-wireless (5G FiWi) access network based bidirectional hybrid 16 × 10 Gbps time and wavelength division multiplexing/ dense wavelength division multiplexing (TWDM/DWDM) Super PON with 2048 split ratio is designed and investigated. Super-passive optical network (Super-PON) is considered as choice for the operators to scale the transmission speed, reach, to build new infrastructure and customer aggregation of optical access networks. The scalability of the optical backhaul based on maximum split ratio of 1/32 for each wavelength channel and a fiber length of 24 km from the central office (CO) to the access point (AP) is analyzed with bit error rate (BER) of 10−9. The performance of the optical backhaul and the wireless front-end, in the proposed FiWi access network, has been evaluated in terms of bit error rate (BER), error vector magnitude (EVM), and signal-to-noise ratio (SNR) of the physical (PHY) layer. In this paper, the FiWi access network is designed based on a wavelengths division multiplexing/time division multiplexing passive optical network (WDM/TDM PON) at the optical backhaul with data rate of 2.5 Gb/s and wireless fidelity-worldwide interoperability for microwave access (WiFi–WiMAX) technologies at the wireless front-end along a 50 m–5 km wireless links with data rate of 54–30 Mb/s, respectively. NG access networks are proposed to provide high data rate, broadband multiple services, scalable bandwidth, and flexible communication for manifold wireless end-users (WEUs). The fiber-wireless (FiWi) access network is a prestigious architecture for next generation (NG) access network.
