Performance assessment of IoT traffic transmission in WDM optical communication systems with parametric optimization

Data traffic on the internet is increasing exponentially due to IoT-based applications. To accommodate large-scale transmission, an optical communication system integrating WDM can provide an efficient solution. In the proposed work, an 8-channel WDM-based IoT-enabled optical system is investigated for three varying loads: 5 Gbps, 10 Gbps, and 15 Gbps. A single-mode fiber of 50 Kms length is analyzed with an EDFA amplifier. The performance is evaluated in terms of BER, Q-factor, eye diagram, and optical spectrum. Additionally, the system parameters like launch power, fiber length, EDFA gain, and dispersion compensating fiber length are also adjusted to improve the system performance. The results indicate improved system performance above threshold, even at higher data rates where dispersion and ISI have more effect. The study demonstrates that dispersion management and spectral optimization are critical for enabling high-data-rate IoT traffic transmission in WDM optical networks, and provides valuable insights for the design of next-generation optical communication systems.
