Housing for a coupling configuration for injecting and/or extracting optical signals

A housing for a coupling configuration for one of injecting and extracting optical signals of at least one optical data channel into or from, respectively, an optical conductor, the coupling configuration having at least one mounting tubelet with at least two optical conductor sections positioned axially one behind another, an injection of light into or extraction of the light from the optical conductor being performed for the optical data channel by reflecting light of the optical data channel at an end face, running obliquely to an optical axis of the optical conductor of one of the optical conductor sections, and reflected light exiting or entering the mounting tubelet at a side thereof having a longitudinal slit formed therein, the housing comprising:

• a housing body having a base with a surface, said housing body further having at least one groove formed therein for holding the mounting tubelet and at least partially defined by said surface of said base, said housing body additionally having at least one recess formed therein at least partially formed in said base defining said groove such that the light exiting or entering the mounting tubelet laid in said groove can transilluminate said base of said groove.
