Abstract
Patente de Invenção: <B>"MéTODO PARA A FABRICAçãO DE UMA FIBRA óTICA PLáSTICA, E UMA FIBRA óTICA PLáSTICA''<D>. A invenção refere-se a um método para a fabricação de uma fibra ótica plástica, em cujo método os materiais plásticos com propriedades óticas adequadas são alimentados para dentro de um aparelho de extrusão de modo a formar uma estrutura de múltiplas camadas onde o índice refrativo diminui gradualmente em uma maneira controlada do interior para fora. A invenção também refere-se a uma fibra ótica plástica. De modo a propiciar a fabricação flexível e contínua de uma fibra de banda larga, o aparelho de extrusão consiste em pelo menos uma unidade extrusora cónica de múltiplas camadas (1) que produz um produto onde as camadas são formadas sem linhas de solda, são simétricas e aderem bem umas nas outras. O número das camadas também pode ser alto.Invention Patent: <B> "METHOD FOR THE MANUFACTURE OF A PLASTIC OPTICAL FIBER, AND A PLASTIC OPTICAL FIBER '' <D>. The invention relates to a method for the manufacture of a plastic optical fiber, in whose method the plastic materials with suitable optical properties are fed into an extrusion apparatus to form a multilayered structure where the refractive index gradually decreases in a controlled manner from the inside out. The invention also relates to a plastic optical fiber In order to provide flexible and continuous manufacturing of a broadband fiber, the extrusion apparatus consists of at least one multi-layer conical extruder unit (1) that produces a product where the layers are formed without welding lines, symmetrical and adhere well to each other. The number of layers can also be high.
