Abstract

—This paper focuses on the challenges of nonlinearities (NLs) and linear distortions (LDs) in radioover-fiber (RoF) transmission systems that limit the achievement of high data rates and multi-user propagation. The aim is to develop a wavelength division multiplexing (WDM)-RoF-based system that reduces NL and LD problems while achieving an optimized structure. The study investigates various system factors such as path cover, transmitted power, output power, and the effectiveness of the suggested model. In addition, the impact of LDs and NL dispersions is explored on RoF systems, and a digital signal processing (DSP) block is proposed to mitigate these issues. To analyze the performance of the proposed RoF system in different scenarios, experiments are conducted using modern modulation formats, fiber lengths, types of filters, and different channel spacings. The experimental analysis shows how the proposed RoF system minimizes LD and NL losses for long-distance and high-capacity data transmission with multi-users. To evaluate the performance of the suggested RoF system, key elements such as transmission range, output power, RF range, channel spacing, and the number of users are used against the bit error rate (BER). The study shows that the proposed system achieves a low BER even in the presence of LD and NL distortions and demonstrates the potential of DSP blocks in mitigating these issues.
