Abstract

Patente de Invenção para <B>"GUIA DE ONDA DE MODO SIMPLES DE LONGO ARRASTE"<D>. é revelada uma fibra de guia de onda ótica de modo simples tendo um núcleo segmentado. Os índices relativos, os perfis de índice de refração e os raios dos segmentos, são escolhidos para proporcionarem propriedades de fibra de guia de onda vantajosamente usadas em ambientes severos, tais como cabos submarinos. A fibra de guia de onda de núcleo segmentado apresenta uma dispersão total negativa sobre a janela de operação de cerca de 1530 nm a 1570 nm, que serve para eliminar formação de soliton. As propriedades chaves de dispersão zero, comprimento de onda de corte, atenuação, e resistência à encurvamento, falham dentro de faixas desejadas. A guia de onda também caracteriza uma dispersão de modo de polarização baixa.Invention Patent for <B> "SIMPLE LONG DRAGON WAVE GUIDE" <D>. a simple waveguide optical fiber having a segmented core is disclosed. Relative indices, refractive index profiles and segment radii are chosen to provide waveguide fiber properties advantageously used in harsh environments, such as submarine cables. The segmented core waveguide fiber has a total negative dispersion over the operating window of about 1530 nm to 1570 nm, which serves to eliminate the formation of soliton. The key properties of zero dispersion, cutting wavelength, attenuation, and resistance to bending, fail within the desired ranges. The waveguide also features a low polarization mode dispersion.
