1. Transmission of a 20 Gb/s NRZ OOK signal throughout a 390 km fiber link and a cascade of 11 x 50 GHz filters and 9 x EDFAs
This paper presents a qualitative analysis of the impact caused by fiber propagation effects and by a cascade of optical filters, designed for 10 Gb/s NRZ OOK transmission, and optical amplifiers on a 20 Gb/s NRZ OOK optical signal traveling a 390 km fiber link. The choice for such bit rate and modulation format has been driven by the 50 GHz bandwidth of the

3. SMART WAVELENGTH ROUTING ASSIGNMENT ON WDM NETWORKS BY FUNCTIONALITY ON PHYSICAL LAYER / ROTEAMENTO INTELIGENTE EM REDES WDM POR FUNCIONALIDADE NA CAMADA FÍSICA / RUTEAMIENTO INTELIGENTE EN REDES WDM POR FUNCIONALIDAD EN LA CAPA FÍSICA
In conventional optical networks, optoelectronic conversions are needed in each node for the sake of a proper packet routing. Simultaneously, intensive managing resources should be allocated to accomplish the routing task. The correct introduction of intelligence and functionality within the network physical layer may lead to some advantages over conventiona
