This article proposes the design and simulation of a radio frequency module based on an Orthogonal Frequency Division Multiplexing (OFDM) system with Quadrature Amplitude Modulation (16-QAM) at a data transmission rate of 10 Gbps and a frequency of 10 GHz using the simulation tool OptSim. For that purpose, a Fiber To The Home (FTTH)-Gigabit Passive Optical Network (GPON) Triple Play system (voice/data service at 2,5 Gbps and digital CATV video service with 16-QAM at 0,8 Gbps) was designed in order to integrate a Radio over Fiber (RoF) module and offer Quad Play services (Triple Play plus mobile Internet). Subsequently, the physical performance of the downlink of the FTTH-GPON system was evaluated after the RoF module was incorporated, based on Optical Performance Monitoring (OPM) parameters such as: Optical Receiver Power, Error Vector Magnitude (EVM), Constellation Diagram, Signal to Noise Ratio (SNR), Bit Error Rate (BER), Quality (Q) Factor, and Eye Diagram. The results show that it may be possible for FTTH-GPON users to have, in addition to Triple Play services, a fourth one (mobile Internet) because the quality of the mobile service is guaranteed within the “last kilometer” for access networks using the current deployment of standard optical fiber, demonstrating the feasibility of the proposed system.
