A New Hybrid Architecture of Radio over Fiber/Wavelength Division Multiplexing in Optical Network

Abstract

Now days, there has been a growing and continuous demand for (high data rates) beyond existing wired and wireless networks. Radio-over-Fiber technology is considered as an efficient and practical solution for providing (broadband wireless access). in this paper, many techniques are used to implement a system that has the facility to offer a (high bit rate), (broadband bandwidth), (more coverage), and (lower cost). So, (RoF) technology was used to transmission signals. Wavelength-Division-Multiplexing (WDM) technique was used to send many signals through the same link, and (DFSK) with Non-Return-to-Zero (NRZ) as modulation format. 80Gpbs separate on two channels was transmitted on (Single-Mode-fiber). The average results obtained from our experience were as follows Max Q- factor = 5.775719, Minimum BER = 3.64*10-6, Total Output Power (dBm) = −27.524, OSNR (dB) = 33.58116 for channel_1, for channel_2 Max Q- factor = 6.098659, Minimum BER = 8.70*10-10, Total Output Power (dBm) = −27.592, OSNR (dB) = 33.88505. All the average result that has from our simulation was very good and acceptable. The simulation and performance test of our experience was done using Optisystem.
