In this paper a genetic algorithm is used as a tool for topology searching and splitter placement in Passive Optical Networks. In order to apply such approach, a graph representation scheme, associated to a street map, is proposed. The formulation has been applied to minimize the amount of optical cabling, number of splitters and power budget, based on standards for the ITU-T GPON parameters.
This paper investigates a novel microstructured optical fiber (MOF) geometry for broadband dispersion compensation. This geometry, defined as D-shaped MOF, or simply D-MOF, is shown to present wideband dispersion characteristics, covering two entire telecommunication bands, namely C- and L-bands. The dispersion value obtained for 1550 nm is around -550 ps/(nm.km). In addition, the high birefringence...
We present a cost-effective EDFA configuration for CWDM applications, using a combination of parallel and series circuits. The developed CWDM EDFA was characterized for gain and noise figure from 1490 to 1610 nm (S, C and L bands) and its performance was evaluated in terms of BER for power and line applications. The obtained results are compared to those arising from the use of a CWDM SOA under the...
