Enabling internal methods in passive optical network architecture for next generation OFDM-PON supporting radio-over-fiber

摘要

In this study, it is focused on designing a novel architecture for Next Generation OrthogonalFrequency DivisionMultiplexing (NG-OFDM), for Passive Optical Networks (PON). This is calledas NGOF-ROFPON (Next generation Optical Fiber – Radio over Fiber PON). In order to improvethe efficiency in providing a seamless data transmission and to extend it to all terrains, theRadio-Over-Fiber (ROF) transmissions is applied among base stations and remote antennas. For abetter decision making on the NGOF-ROFPON, a simulation-based experiment is carried out onboth OFDM (Orthogonal Frequency Division Multiplexing) and its RF (Radio Frequency) outputsignals quality performance at receiver side is compared. By analyzing the system parametersin the simulation results collaboratively in optical broadband OFDM and RF OFDM over PONthe best performance for a PON architecture is decided as a optimum method to the PON fornext generation and referred as NGOF-ROFPON. Moreover, from the simulation results, byselecting the best modulation technique, the spreading of the signal due to the downstream andupstreamprocess is controlled and such signals are used in various frequency-based RF signalsover various distances in single mode fiber PON.
