摘要： A receptacle connector comprises a receptacle ferrule, and a receptacle housing including a cavity housing the receptacle ferrule and a cavity housing a plug connector. The receptacle ferrule includes an optical coupling surface (front surface). An opening area of the cavity on a cross section vertical to an inserting direction of the plug connector to the receptacle housing is smaller than an opening area of the cavity on the cross section vertical to the inserting direction. In a second state after being optically coupled, the optical coupling surface (front surface) is positioned inside the cavity.

摘要： A ferrule 10 includes holding holes 16, a light incidence/emission plane 21 to pass light entering or emitted from optical fibers F2 respectively held at the holding holes 16, lenses 31 disposed on an optical axes between the respective holding holes 16 and the light incidence/emission plane 21, and two or more guide portions. A second optical axis L2 between the light incidence/emission plane 21 and the ferrule 10 on the other side is inclined relative to a Z direction. A positional relation between the guide portions is 180-degree rotationally symmetric around a reference axial line extending in the Z direction. The lenses 31 is disposed disproportionately in a direction opposite to an inclination direction of the second optical axis L2 from a position line-symmetric relative to a straight line crossing with the reference axial line and parallel to an X direction.
