| dc.description.abstract | The current internet demand requires high spectral efficiency. The integration of CO-OFDM with a WDM system has high spectral efficiency by dividing subcarriers orthogonally. To transmit within a single optical fiber, multiple data streams come together into one by a WDM system. This paper aims to investigate the effect of parametric value difference on the performance of the WDM system as well as CO-OFDM integrated with WDM. The power of the CW laser, the power of the EDFA, the length of DCF, and the EDF are the parameters used. The performance of the system is measured by BER, Q-factor, Eye Opening Height, and OSNR. The system is designed and analyzed using the ”Opti-System” simulation tool. The initial focus is to design WDM without a CO-OFDM system to study the parameters that influence the system’s performance. CW laser power is accomplished better at 0 dBm instead of at 10 dBm because when the intensity of light increases, the nonlinearity effects are high. At 100mW, EDFA power dispatches better than if it were at 200mW. When the EDFA amplifies the signal power simultaneously, the noise power is amplified thus, the system’s performance is minimized. DCF length is proportional to the length of single-mode fiber, resulting in improved performance. If the above parameter values are not within the normal range, the performance of the system becomes highly distracted. The subsequent task involves understanding and analyzing which factors limit the transmission capacity and the reachability of CO-OFDM with WDM. The effect of the transmitted data and length on the system’s performance is observed. | |
