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

Abstract

Summary In this study, it is focused on designing a novel architecture for Next Generation Orthogonal Frequency Division Multiplexing (NG‐OFDM), for Passive Optical Networks (PON). This is called as NGOF‐ROFPON (Next generation Optical Fiber – Radio over Fiber PON). In order to improve the efficiency in providing a seamless data transmission and to extend it to all terrains, the Radio‐Over‐Fiber (ROF) transmissions is applied among base stations and remote antennas. For a better decision making on the NGOF‐ROFPON, a simulation‐based experiment is carried out on both OFDM (Orthogonal Frequency Division Multiplexing) and its RF (Radio Frequency) output signals quality performance at receiver side is compared. By analyzing the system parameters in the simulation results collaboratively in optical broadband OFDM and RF OFDM over PON the best performance for a PON architecture is decided as a optimum method to the PON for next generation and referred as NGOF‐ROFPON. Moreover, from the simulation results, by selecting the best modulation technique, the spreading of the signal due to the downstream and upstream process is controlled and such signals are used in various frequency‐based RF signals over various distances in single mode fiber PON.

“…[18][19][20] OFDM technique is an effective approach to minimize system cost. 21 Therefore, there are some systems on integrated OFDM-PON and RoF systems. 22,23 Nevertheless, with the signal bandwidth and frequency raising, some spectrum resources are wasted and system costs are increased.…”
