Abstract

<B>SISTEMA DE MULTIPLEXAçãO POR DIVISãO DE COMPRIMENTO DE ONDA<D> Uma rede de fibra óptica de alta capacidade {100, 200} inclui multiplexação por divisão de comprimento de onda (WDM) dentro da região de comprimento de onda de 1,4 mícron (<109>m) (isto é, 1.335-1.435 nm). Tal sistema inclui a fibra óptica [130], cuja perda máxima na região de 1,4 <109>m é menor do que a sua perda a 1.310 nm. A fibra óptica tem um comprimento de onda para dispersão zero (sym~ o~) a aproximadamente 1.310 nm e uma dispersão linear entre aproximadamente 1,5 e 8,0 ps/nm-km dentro da região de 1,4 <109>m. Pelo menos três canais de WDM operam a 10 Gb/s na região de comprimento de onda de 1,4 <109>m e têm uma separação entre canais de 100 GHz. Em uma modalidade ilustrativa da invenção, um canal de difusão de televisão, que tem modulação de faixa lateral; residual de amplitude modulada, opera simultaneamente na região de 1,3 <109>m (isto é, 1.285-1.335 nm) e/ou na região de 1,55 <109>m (isto é, 1.500-1.600 nm). Em outra modalidade da invenção, 16 canais de dados digitais são multiplexados em conjunto na região de 1,55 <109>m, cada canal operando a aproximadamente 2,5 Gb/s. Os amplificadores Raman [103, 113] são usados para amplificação nas regiões de comprimento de onda de 1,3 <109>m e 1,4 <109>m, enquanto um amplificador Erbium [123] é usado para amplificação na região de comprimento de onda de 1,55 <109>m.
