Optical fiber connector and adapter capable of preventing dust

Abstract

An optical fiber connector configured to be inserted into an optical fiber adapter according to the present invention is provided. The optical fiber connector includes a housing and an elastic body. The housing has a front end with an opening formed thereon. The elastic body is positioned on the housing and around the opening. When the optical fiber connector is inserted into an axial cavity of the optical fiber adapter, a hollow cylinder of the optical fiber adapter will be inserted into the optical fiber connector through the opening on the front end of the housing and the elastic body on the housing will be in contact with inner walls of the axial cavity of the optical fiber adapter.
