This research models an 80-channel WDM Radio over Fiber (RoF) system for dense channel deployment using Optisystem simulation software and analyzes its performance. The analysis focuses on the system's Quality Factor (QF) performance for 100–300 km transmission distances and power levels. Comparisons of NRZ and RZ modulation systems focused on power variation's effect on system performance. For shorter and medium distances, RZ modulation surpasses NRZ, with notably better QF values at 100 and 150 km. Over 200 km, RZ modulation improved signal quality and deterioration resistance. Beyond 250 km, both modulation systems performed poorly, although RZ had a minor edge. System performance depended on power fluctuation, with lower power levels (− 5 dBm) leading to lower QF values. Power increased the QF at all lengths, however, signal degradation reduced the advantage at long transmission distances. Advanced modulation formats and adaptive power management algorithms will be investigated to enhance long-distance deployment performance. Dense WDM RoF systems will need better dispersion correction and power optimization to be more efficient and scalable. Next-generation communication networks need great performance and an energy economy; thus, these concerns are essential.

摘要

This research models an 80-channel WDM Radio over Fiber (RoF) system for dense channel deployment using Optisystem simulation software and analyzes its performance. The analysis focuses on the system's Quality Factor (QF) performance for 100–300 km transmission distances and power levels. Comparisons of NRZ and RZ modulation systems focused on power variation's effect on system performance. For shorter and medium distances, RZ modulation surpasses NRZ, with notably better QF values at 100 and 150 km. Over 200 km, RZ modulation improved signal quality and deterioration resistance. Beyond 250 km, both modulation systems performed poorly, although RZ had a minor edge. System performance depended on power fluctuation, with lower power levels (− 5 dBm) leading to lower QF values. Power increased the QF at all lengths, however, signal degradation reduced the advantage at long transmission distances. Advanced modulation formats and adaptive power management algorithms will be investigated to enhance long-distance deployment performance. Dense WDM RoF systems will need better dispersion correction and power optimization to be more efficient and scalable. Next-generation communication networks need great performance and an energy economy; thus, these concerns are essential.
