A receptacle connector includes a housing and first and second sets of conductive terminals attached to a respective first and second main surfaces of the housing. Each conductive terminal has a first end, a second end and a contact portion therebetween. The first end is offset from the contact portion along a direction perpendicular to the contact portion. The contact portion is attached to one of the first and second main surfaces by insert-molding. The first end extends through an end surface of the housing. The first ends are aligned in one row parallel to the first and second main surfaces such that the molding process is simplified. In a one type of example receptacle connector, the conductive terminals are strongly and precisely attached to the housing, hence the physical dimension can be ensured, and the mateability with counterpart plug connector as well as manufacturability can be improved.

An optical cable assembly is provided, an optical cable provided with one or more optical fibers, a strain-relieve device mounted on the optical cable and configured to provide a strain relieve when the optical cable is fed into an optical module through an opening in a housing of the optical module, wherein the strain-relieve device is provided with an adjustment mechanism configured to adjust a distance between an end portion of the one or more optical fibers and the strain-relieve device. Furthermore, an optical module and a method for assembling an optical cable assembly are provided.
