Evaluación del rendimiento del sistema de multiplexación por división de longitud de onda utilizado en redes ópticas pasivas.

Abstract

In this master thesis, the performance evaluation of wavelength division multiplexing (WDM) system used in passive optical networks (PON) is carried out. The purpose of this work was to describe the standard PON technologies and next generation PON technologies in terms of capacity to provide 2.5 Gbps downstream and 1.25 Gbps upstream transmission rate. The selected optical splitter ratios for the different technologies are shown as the only feasible solution to satisfy the required minimum service level agreements. In this GPON topology, WDM technology is considered for residential subscribers with a ratio of 1∶32. The results show that although time division multiplexing (WDM) is the most economical solution when the number of subscribers is not dominant. WDM technology is the most convenient alternative for high subscriber ratios in the PON.
