Abstract

Patente de Invenção: <B>"FIBRA óPTICA DE COMPENSAçãO DE DISPERSãO E LINHA DE TRANSMISSãO USANDO A FIBRA óPTICA"<D>. Proporciona-se uma fibra óptica de compensação de dispersão que reduz a dispersão nas faixas de comprimento de onda de 1,5 Ám e 1,3 Ám, e uma linha de transmissão óptica usando a fibra óptica. Um primeiro núcleo lateral (2), um segundo núcleo lateral (3) e uma blindagem (5) são dispostos nessa ordem sobre o lado externo de um núcleo central (1). A relação entre uma diferença de índices de refração <30>1 do núcleo central (1) para a blindagem (5), uma diferença de índices de refração <30>2 do primeiro núcleo lateral (2) para a blindagem (5), e uma diferença de índices de refração <30>3 do segundo núcleo lateral (3) para a blindagem (5) é ajustada para ser <30>1 > <30>3 > <30>2, em que 0,8% <243> <30>1 <243> 1,3%, -0,5 <243> <30>2/<30>1 <243> -0,35 e 0,2% <243> <30>3 <243> 0,3%, e a relação de diâmetros entre o núcleo central (1), o primeiro núcleo lateral (2), e o segundo núcleo lateral (3) é ajustada para ser 1:2 a 2,5:2,5 a 3,5. A fibra óptica de compensação de dispersão é conectada a uma fibra óptica de modo simples, e o valor de dispersão na faixa de comprimento de onda de 1,5 Ám da fibra óptica conectada é ajustado para ser -1 ps/nm/km a 1 ps/nm/km, e o valor de dispersão na faixa de comprimento de onda de 1,3 Ám da fibra óptica conectada é ajustado para ser -5 ps/nm/km a 5 ps/nm/km.
