Abstract
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.
