Abstract: In order to simplify mounting and cabling of optoelectronic plug connectors (3, 3?) and—equipped therewith—subdistribution units (6) and subdistribution systems, the use of special module housings (100) is proposed. The latter can accommodate a plurality of, in particular eight, identical and/or different optoelectronic transducers (2, 2?) and are installed in the plug connectors (3, 3?) between the electrical plug contacts (311) and the multi-core optical cables (58), i.e. the cores (51) thereof. Susceptibility to errors is considerably improved as a result and mounting is significantly simplified as a result of the improved clarity.
