Abstract

Patente de Invenção para <B>"ESTOQUE DE ALIMENTAçãO DE CLORETO DE GERMANIO E SILOXANO PARA FORMAçãO DE VIDRO DE SìLICA E PROCESSO"<D>. é revelado um processo de fabricação de uma pré-forma de guia de onda ótica e guias de onda óticas que podem ser estiradas em uma fibra. Um estoque de alimentação que inclui uma mistura de siloxano e cloreto de germânio e um aparelho de manufaturamento de pré-forma de guia de onda ótica é também revelado. A revelação inclui adicionalmente a mistura antes de deposiçào e uso de silixano de alta pureza com cloreto de germânio de alta pureza para produzir sílica dopada com germânio. As linhas de distribuição para o estoque de alimentação no lado de deposição podem ser aquecidas a 175°C a 200°C.Invention patent for <B> "STOCK OF GERMANIUM AND SILOXAN CHLORIDE FEED FOR GLASS FORMING OF SILICA AND PROCESS" <D>. a process is disclosed for manufacturing an optical waveguide preform and optical waveguides that can be stretched on a fiber. A feed stock that includes a mixture of siloxane and germanium chloride and an optical waveguide preform manufacturing apparatus is also revealed. The development further includes mixing before deposition and using high purity silixane with high purity germanium chloride to produce germanium doped silica. The distribution lines for the supply stock on the deposition side can be heated to 175 ° C to 200 ° C.
