Simulador de código aberto para redes ópticas considerando multiplexação por divisão espacial e o impacto de penalidades físicas.

Abstract

The growing demand for data traffic is requiring more efforts from communication systems, in searching for alleviating or eliminating limiting factors of capacity and bit rate throughput through new technologies. In the field of optical communications, elastic optical networks (EON) are advantageous compared to conventional optical networks, which use wavelength division multiplexing (WDM), as they enable a more efficient use of the spectrum frequency. Spatial Division Multiplexing (SDM) optical networks have also been analyzed as an alternative to provide communications systems with greater capacity, since they make use of the spatial diversity of fiber — whether it has multiple modes, cores or even a packet of fibers. In this context, this work presents an extension of an open source simulator for WDM/EON optical networks, considering now its application in SDM-WDM and SDM-EON networks and the impact of physical penalties associated with them: interference between cores and between modes . For the purpose of validating it, simulations of specific scenarios were performed in order to compare the results with those found in the literature and those obtained in other computational tools.
