Abstract

Patente de Invenção para "FIBRA DE GUIA DE ONDA DE MODO SIMPLES DE DISPERSãO NEGATIVA". é revelada uma fibra de guia de onda de dispersão total negativa, tendo uma atenuação baixa e resistência suficientemente boa à perda de encurvamento, cuja atenuação não é impactada pelo cabeamento ou, de outro modo, amortecimento da guia de onda. A inclinação de dispersão total da fibra de guia de, onda é positiva de modo que o comprimento de onda de dispersão zero é maior do que 1600 nm. A fibra de guia de onda pode vantajosamente ser usada em uma ligação tendo laser de retorno distribuído como uma fonte de sinal. A dispersão negativa da guia de onda de acordo com a invenção comprime o pulso de sinal lançado quando o laser é positivamente estridulado. O laser e operado em inclinações ótimas, que resulta em estrídulos positivos, mas nenhuma penalidade de dispersão é incorrida na ligação. A fibra de guia de onda de acordo com a invenção pode também ser vantajosamente usada como uma fibra de compensação de dispersão em uma ligação de telecomunicações multiplexada de alta performance.
