Title: Performance Analysis of a 40 Gbps Dense Wavelength Division Multiplexing (DWDM) System Using Optiwave OptiSystem
Abstract
This paper presents a comprehensive simulation study of a high-speed Dense Wavelength Division Multiplexing (DWDM) optical communication system using Optiwave OptiSystem software. The primary objective is to analyze the performance of a 40 Gbps transmission link over a distance of 100 km, evaluating the impact of chromatic dispersion and non-linear effects on signal quality. Key performance indicators such as Bit Error Rate (BER), Quality Factor (Q-factor), and Eye Diagrams are investigated. The simulation results demonstrate the efficacy of dispersion compensation modules in mitigating signal degradation, ensuring reliable data transmission with a Q-factor greater than 6 at the receiver. optiwave optisystem
Modern optical networks no longer rely on simple on-off keying (OOK). OptiSystem natively supports advanced coherent modulation formats including: Title: Performance Analysis of a 40 Gbps Dense
The receiver section employs a PIN photodetector with a responsivity of 1 A/W and a dark current of 10 nA. The electrical signal is then passed through a low-pass Bessel filter to remove high-frequency noise components. Finally, the signal is analyzed using a BER Analyzer and an Oscilloscope Visualizer to generate eye diagrams and calculate the Q-factor. Modern optical networks no longer rely on simple
