Abstract
An optoelectronic module is disclosed, which can be connected optically and electrically in a simply way. The optoeletronic module consists of a SMD-housing (1) for the electrical connection and a connector (5), on which a MT-plug is fitted, for the optical connection. The SMD-housing is assigned to the MT-plug. It includes a plug connector (5), which contains the optical/electrical interface and is positively fixed in the housing.
