Otimização técnica do enlace óptico entre os diversos campi da UNIPAMPA

Abstract

The optical fiber has characteristics which favor the propagation of electromagnetic signals from one point to another, when compared to other waveguides. The maximum performance of optical fiber as a waveguide depends on the appropriate choice of the network topology, both in its physical and logical aspects. The development of more efficient network topologies allows the possibility for improvements of already installed links. After a careful study and technical assessment of network traffic characteristics, it is possible to verify if the physical topology used is the most appropriate and to propose changes that will lead to improved communication performance. In this context, this work presents important technical advances for the interconnection of the various campuses of the Federal University of Pampa (UNIPAMPA). These advances can be achieved through the adoption of the most appropriate physical topology to link the ten campuses of the institution located along the west border of Rio Grande do Sul, as well as the rectory, distributed in two addresses in the Bagé city. The proposed topology is of mesh type and is evaluated in terms of power budget (signal range), time budget (dispersion sensitivity) and cost budget. The proposed network has advantages such as greater robustness to failures due to disruptions or network congestion, and a greater quality of service due to the reduction of the latency in the network, i.e., the reduction of the time needed to establish the communication. This work can be used as a theoretical background, to help in decisions for future expansions in the optical infrastructure of UNIPAMPA.
