Abstract
Patente de Invenção: <B>"FIBRA óTICA DE PEQUENA INCLINAçãO DE DISPERSãO CROMáTICA"<D>. A invenção refere-se a uma fibra ótica monomodal de dispersão deslocada, que apresenta, em uma faixa de comprimento de ondas de 1400 a 1650 nm, um máximo da dispersão cromática e uma inclinação de dispersão cromática em valor absoluto inferior a 0,05 ps/nm².km. O máximo é vantajosamente único na faixa de comprimentos de onde de 1400 a 1650 nm. A fibra apresenta por outro lado uma inclinação de dispersão inferior em valor absoluto a 0,03 ps/nm².km em uma faixa de comprimento de onde de 1530 a 1580 nm. A fibra da invenção é especialmente adaptada a sistemas de transmissão de multiplexação em comprimentos de ondas.
