Performance Analysis of RoF PON System based on Orthogonal Frequency Division Multiplexing Technique

Abstract

The requirement of high bandwidth, high flexibility, high mobility and high data rate at lower cost can be met with a real convergence of radio over fiber (RoF) and orthogonal frequency division multiplexing (OFDM) techniques. This paper compares the results of OFDM as a modulation for radio over fiber in passive optical network (PON) for 288km single mode fiber with that of dispersion compensator fiber. The four optical network units (ONUs) are connected by using 1:4 ratio passive optical splitter. A laser source of 1550 nm, bit rate of 10 Gbits/sec is used to simulate the system.

Radio over fiber system based on a hybrid link for next generation of optical fiber communication

“…Talli and Townsend [7] proposed Hybrid DWDM-TDM long-reach PON for next-generation optical access. Pehraj et al [8] have shown that the requirement of high bandwidth, high flexibility, high mobility and high data rate at lower cost can be met with a real convergence of radio over fiber (RoF) and orthogonal frequency division multiplexing (OFDM) techniques. To increase the bandwidth Alateeq et al [9] present a Design of Broadband RoF PON for the Last Mile, Zhang et al [10] proposed a novel architecture for nextgeneration passive optical network (PON) based on electrical code division multiplexing orthogonal frequency division multiplexing (ECDM-OFDM) access.…”
