Abstract
Patente de Invenção: <B>''PROCESSO DE FABRICAçãO DE UMA MULTITIRA DE FIBRAS óTICAS SEPARáVEL EM PELO MENOS DUAS TIRAS DE FIBRAS óPTICAS"<D>. Processo de fabricação de uma multitira (10) de fibras ópticas (1), separável em pelo menos duas tiras, que compreende: uma primeira etapa de realização de uma multitira (10) que contém as ditas fibras lado a lado, paralelas, sensivelmente em um mesmo plano que define as faces (19a, 19b) da dita multitira, embutidas no interior de uma matriz comum (15, 16), por revestimento com pelo menos uma camada de revestimento que realiza a multitira e depois por termoendurecimento da dita camada, e uma segunda etapa de realização de pelo menos uma linha de ruptura preferencial entre duas fibras ópticas vizinhas, que compreende pelo menos um entalhe (11a, 11b) na camada de revestimento, paralelamente ao eixo X das fibras ópticas da multitira, em um plano (P~ o~) perpendicular às faces da tira, sensivelmente mediano em relação às ditas fibras ópticas vizinhas, por um dispositivo de entalhamento que compreende um meio de entalhamento (17a, 17b) de pelo menos uma das faces da multitira.
