“…(6)(7)(8) have demonstrated that as optical signal wavelength increases, this leads to decrease in transmitted signal power, transmitted signal bandwidth, and transmission bit rate capacity at different fiber cable lengths. As well as fiber cable length increases, this results in decreasing of transmitted signal power, transmitted signal bandwidth, and transmission bit rate capacity at constant operating optical signal wavelength.…”

“…In such an ADM with two control pulses, for example with a 4x40 Gbit/sec OTDM signal, the incoming data signal would be split and one control signal at 40 GHz for wavelength conversion of the dropped channel would be applied to the first part of the OTDM signal, and one control signal at 3x40 GHz to convert the wavelength of the through channels would be applied to the second part of the OTDM signal [6]. The increase in traffic demand associate with new applications is triggering a dramatic growth in capacity requirements for medium and long haul transport networks.…”

“…For most PIN receivers, the noise is generally thermally limited, which is independent of signal current. The BER is related to the SNR as follows :

BER \approx (\frac{2}{π italicSNR}) exp (\frac{- italicSNR}{8})

Power link budgets are prepared for wireless optical communication systems to illustrate the optical losses that happen during transmission. This paper has presented optical wireless links, which offer ultra multi gigabit per second data rates and low system complexity. For ground space and/or terrestrial communication systems, these links suffer from atmospheric loss mainly due to fog, and scintillation. Optical wireless links provide high bandwidth solution to the last mile access bottleneck. However, an appreciable availability of the link is always a concern. Wireless optical links are highly weather dependent, and fog is the major attenuating factor reducing the link availability. Link margin, received signal power, transmission bit rate, bit rate distance product, signal-to-noise ratio, and BER are the major interesting design parameters in the current study.

Resumo    Nós investigamos numericamente a confiabilidade da utilização de um anel de recirculação óptico (RCL) em prever o desempenho de um sistema e os efeitos causados pelo cascateamento de elementos ópticos em um sistema de transmissão. Para validar esta ferramenta, nós conduzimos simulações numéricas do anel de recirculação baseadas em duas demonstrações experimentais: (i) dez voltas no anel com um único canal, modulado a 10 Gb/s, em um enlace de 25 km por volta e (ii) um sistema de transmissão WDM usando um optical add-drop multiplexer (OADM), baseado na tecnologia de fibra com grade de Bragg. Os resultados experimentais e de simulação apresentaram-se de acordo. 1 Palavras -chaves     Anel de Recirculação, Optical Add-Drop Multiplexer (OADM),
