Abstract

"FIBRA óTICA, COMPENSADOR DE DISPERSãO QUE FAZ USO DA MESMA, E SISTEMA DE TRANSMISSãO óTICA". A presente invenção refere-se a uma fibra ótica que apresenta uma função de compensação da característica de dispersão de uma linha de transmissão ótica na banda S e que preferivelmente apresenta uma função de filtro para interrromper os comprimentos de onda que excedem a banda S. A fibra ótica da presente invenção apresenta camadas de vidro de três camadas que apresentam diferentes composições entre as camadas vizinhas. Quando a relativa diferença de índice refrativo máxima de uma primeira camada de vidro (1) formada na parte mais interna da fibra ótica com relação à uma terceira camada de vidro (3) (camada padrão) for representada por <30>1, e a relativa diferença de índice refrativo mínima de uma segunda camada de vidro (2) como uma segunda camada originária da parte mais interna da fibra ótica com relação à camada padrão for by <30>2, as seguintes desigualdades serão satisfeitas: 1,0% <243> <30>1 <243> 0,3%, e -1,0% <243> <30>2 <30> - 0,4%. O valor de dispersão no comprimento de onda ajusta da banda S será ajustado em -8ps/nm/km. Por exemplo, o valor alcançado com a divisão da dispersão pelo declive de dispersão é igual a um valor positivo menor do que 300, e a perda na transmissão no comprimento de onda de 1520 nm é ajustada como sendo maior do que a perda na transmissão no comprimento de onda de 1500 nm em 1 dB ou mais.
