Optimization of High Performance Generation Method Based RoF System by Employing Optic Amplifier Link

The demands of Academia, Industries, data-hungry applications and user-defined services conceptualizing the next generation networks such as fifth Generation (5G) or sixth Generation (6G) Wireless Networks. The major challenges for next generation networks are energy efficient communication and green environment with potential health issues. The important substitute for green radio communication is Radio over Fiber System (RoF) System. The high quality, high security, large capacity, optimized energy consumption, low latency, economic solution for long distance etc., are assured by RoF system. The 120° phase shift based high performance RoF system is utilized against intermodulation (IM3) terms. In this paper, the performance of 120° phase shift based RoF system with erbium doped fiber amplifier (EDFA) is analysed, modelled and simulated. The impact of noise and distortion environment w.r.t. input RF signal power are investigated. Further, the spurious free dynamic range (SFDR) of proposed system with EDFA is also evaluated while considering fundamental and IM3 power variations. The SFDR is found as 149.5 and 122.22 dB/Hz^2/3 for proposed system with and without EDFA, respectively. This dynamic range calculation of proposed system defines the need of dispersion compensation fiber (DCF) for proposed system with EDFA for nonlinearities and challenging applications.
