Performance Optimization for (NG-RoF) Systems: Mitigating Nonlinear Effects in Long-Distance Transmission

Within the last ten years, several modern technologies were invented, and different types of services were subscribed to and used in daily life. All these are in need of high data rate and wide coverage in respect to mobile communication, and it thus needs an advanced generation to meet these performances as dictated by the end users. This paper is intended to advocate radio-over-fiber technique in 5G systems, improving standards of techniques for ensuring effective wireless communications coverage. But the problem was an issue of nonlinear effect causing some failure in the system performance, especially at a distance of 400km in transmission and data rate impact at fifth generation-the data downloaded is up to 100 GBps. It uses a major concept from signal processing within NG5 RoF for transmission and reception. The defects take place starting off with the use of the transmitted signal at first instance within modulated 16QAM while it reaches receiving through the power account until the filtering to BER, which is taken up to distance transmission, initially starting from the 100 n right up to a distance of 400 km, hence. Worth remarking is that all the models presented in this report were simulated using Optisystem 18.
