Simulation model of next-generation networks

Abstract

Next-generation networks have proven to be a key solution to meet the growing demand for high speeds and reliability with secure communication.This thesis focuses on the development of a simula- tion model of a new-generation optical network using OptiWave software applications. The primary objective is to explore different deployment scenarios of an optical amplifier to optimise network reach. The paper begins by examining the challenges associated with next-generation networks, including increasing bandwidth requirements and limitations of existing network architectures. The computer model of the new generation NGPON2 (TWDM-PON) network is then created in the Optiwave Optisystem environment. with respect to key components such as transmitters, receivers, and optical amplifiers. The model contains components that are able to evaluate parameters such as signal power levels, modulation schemes, and fibre characteristics. The built simulation model is adjusted to test different scenarios of amplifier deployment. The simulation studied different locations of optical amplifiers and their effect on the power level and the effect on the signal quality, i.e., the power and attenuation balance of the network reach. Through these simulations, knowledge is obtained for optimisation to get better network reach and performance. The achieved simulated outputs for various simulation settings are thorough evaluated and analyzed. Key performance met- rics, including signal quality, bit error rate, and network reach, are evaluated to compare and discuss the effectiveness of different deployment strategies.This work contributes to the understanding and optimisation of new generation networks, the development of simulation model in the Optiwave Optisystem environment.The findings provide valuable insights for designers and engineers. The networks that enable efficient and reliable design of high-speed communication infrastructure.
