Abstract
Managing the users multimedia and long-range based demands, the radio over fiber (RoF) mechanism has been introduced recently. RoF mingles the optical and radio communication frameworks to increase mobility and offer high capacity communication networks (CNs). In this paper, a full-duplex RoF-based CN is investigated for the next-generation passive optical network (PON), utilizing wavelength division multiplexing (WDM) technology. The desolations on account of optical and electronic domains (OEDs) are addressed, using dispersion compensation fiber (DCF) and optical and electrical filters, including modulation scheme. The analytical and simulation models are analyzed in terms of phase error (PE), radio frequency (RF), fiber length and input and received powers. The performance of the proposed model is successfully evaluated for 50 km range, −40 to −18 dBm received power, −20 to 0 dBm input power, where below 10−6 bit error rate (BER) is recorded. Thus, this signifies that the presented model exhibits smooth execution against OEDs impairments.

The traffic on internet services has been increased exponentially in the last few years, and it is expected that the data rate demands will touch the zettabyte digit between 2022 to 2025 [1,2]
In [21], Coelho et al have proposed the OFDM based wavelength division multiplexing (WDM) radio over fiber (RoF) system by applying fiber brag grating (FBG). These previously proposed solutions are limited to addressing nonlinear impairments (NLIs) and peak to average power ratio impairments (PAPRIs) for long range transmission communication networks (CNs)
In this paper, based on passive optical network (PON), a full duplex RoF system is presented, using WDM technology to decrease the factors of NLIs and PAPRIs
Summary
The traffic on internet services has been increased exponentially in the last few years, and it is expected that the data rate demands will touch the zettabyte digit between 2022 to 2025 [1,2]. The wired based PONs contain extra issues like nonlinear impairments (NLIs) while transmitting high bandwidth data over fiber for long range, which badly disturbs the system flexibility [5]. The physical-less based communication network (CN) presents accurate probability within the flexible environment; it fails to accommodate a considerable number of users with the high bandwidth capacity of long range transmission [6]. The wavelength division multiplexing (WDM) technology and advanced modulation schemes have developed the fidelity many times of the RoF system. This advanced methodology of CN minimizes the NLIs, and the system performance increases in terms of transmission range, number of users and capacity.
