Apparatus for handling data conductors

Apparatus for handling data conductors, in particular optical waveguides, and junction points between data conductors, in particular between optical waveguides, having a housing (11) and having assemblies, which are accommodated in the housing (11), for connecting and/or laying data conductors, it being possible to insert data conductors in an interior space, which is defined by the housing, and to guide data conductors out of the said interior space by means of at least one side wall (14) of the housing, specifically by means of openings (15) made in the side wall, whereby at least one opening (15), by means of which data conductors can be inserted into the interior space and guided out of the said interior space, is defined on at least one side wall (14) of the housing (11) by a section (18) of the side wall which can be broken out of the side wall (14), specifically in such a way that, in order to provide a relatively small opening, a first, inner subsection (19) with a relatively small outer contour can be broken out of the side wall (14), and in that, in order to provide a relatively large opening, a second, outer subsection (20) with a relatively large outer contour can additionally be broken out of the side wall (14).
