Abstract
Patente de Invenção para "FIBRAS DE NúCLEOS MúLTIPLOS E GEREINCIADAS PARA DISPERSãO DE MULTIMODO". Trajetórias óticas ao longo de fibras, incluindo núcleos múltiplos ou modos múltiplos, são dispostas com características de dispersão positiva e negativa. Mecanismos de acoplamento ou de conexão regulam os comprimentos relativos de deslocamento entre as trajetórias tendo características de dispersão diferentes, de modo que a dispersão total das trajetórias combinadas se aproxima de zero sobre uma faixa de comprimentos de onda de sinal pretendida para transmissão.
