Hybrid gigabit-passive optical network (GPON) is one of the hybrid optical networks, it integrates both Wave length Division Multiplexing (WDM) GPON and Time Division Multiplexing (TDM) GPON into a single passive network, which lowers the energy consumption, networking expenditure and boosts the data rate. In this paper, Radio over Fiber Technique of 10 GB/s GPON network architecture is implemented and verified using Quadrature Phase Shift Keying Modulation of 2.4 GHz radio frequency. Single-mode fiber of length 50 km is used to propagate the radio signals. Commercial OptiSystem simulation software is used to simulate the model. In total, 32 and 64 users are supported through this model. Based on the response of the constellation diagram, received power, eye diagram, and optical signal-to-noise ratio, the system is analyzed.
