Abstract:
The study outlines the simulation of two pulse generators for the enhancement of optical fiber access transmission networks with flow rates of 5 and 10 Gbps and transmission ranges of 50 km, 100 km, and 150 km. Gaussian and hyperbolic secant pulse generators are used. For effective transmission, the proposed pulse generators are combined with both an electro-absorption modulator (EAM) and a Mach-Zehnder modulator (MZM). For various bit sequences, we compared the maximum quality factor with length. In the best situations for different bit sequences, the signal power amplitude is measured for both optical fiber and PIN photodetector using optical time-domain visualizer and RF spectrum analyzer. It is observed that for various bit sequences, the Gaussian pulse generator/EAM has shown an efficient rise in Q factor value as compared to proposed pulse generators/MZM.
