Abstract

Patente de Invenção: "FIBRA óTICA E LINHA DE TRANSMISSãO óTICA USANDO A FIBRA óTICA". Uma fibra ótica para a formação de uma linha de transmissão ótica adequada para a transmissão de multiplexação de divisão de comprimento de onda pela conexão a uma fibra ótica de dispersão positiva é provida. Fora, uma primeira camada de vidro (1), uma segunda camada de vidro (2), uma terceira camada de vidro (3) e uma quarta camada de vidro (4) são seq³encialmente dispostas. A quarta camada de vidro (4) deve ser uma camada de referência para um padrão de um índice de refração. Uma diferença relativa de índice de refração <30>1 da primeira camada de vidro para a camada de referência é regulada de 1,6% a 2,6%, inclusive, uma diferença relativa de índice de refração <30>2 da segunda camada de vidro é regulada de -0,65% a -0,4%, inclusive, e uma diferença relativa de índice de refração <30>3 da terceira camada de vidro é regulada de 0,15% a 0,5%, inclusive. Uma relação dentre um diâmetro externo d1 da primeira camada de vidro, um diâmetro externo d2 da segunda camada de vidro e um diâmetro externo d3 da terceira camada de vidro é regulado para 2,5 <243> (d2/d1) <243> 3,0, e 1,5% <243> (d3/d2) <243> 3,0.
