  • Publication number: 20110198035
    Abstract: An adhering jig for an adhesive connecting member is provided, in which the adhesive connecting member can be adhered without being broken even if it is twisted during connection of an optical fiber. The adhesive connecting member of the present invention has a tabular member having insertion holes fitting a shape of the optical connector, and an adhesive connecting member having a certain size. The adhesive connecting member has a strongly adhesive layer and non-adhesive layer, and the adhesive connecting member was arranged at a bottom of the insertion hole via the weakly adhesive layer, so that the non-adhesive layer is lower.
