Abstract

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. 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. 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. 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. 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. In addition, the maximum acceptable wireless reach for the proposed system is 110 and 120 km for downstream and upstream transmission respectively along with 50 km fiber range serving 2048 users for future based internet of things (IoT) applications. Additionally, the comparative performance of the proposed bidirectional 5G FiWi access network based hybrid TWDM/DWDM Super PON with 2048 split shows its superiority relative to existing models.
