  • Publication number: 20210063649
    Abstract: A fiber optic connector includes a housing having an internal cavity and a front opening. A back post has an internal cavity, a front opening and a rear opening. The back post is operatively connected to the housing so that the internal cavity of the back post communicates with the internal cavity of the housing. At least two ferrules are disposed at least partially within the internal cavity of the housing and are exposed through the front opening of the housing. Each ferrule has a cylindrical shape and includes a flange. Each ferrule couples to an optical fiber. A fiber guide is coupled to each ferrule. Each fiber guide receives one of the optical fibers. Each fiber guide extends rearward from the ferrule. Each fiber guide extends in the internal cavity of the housing and the internal cavity of the back post. Each fiber guide is bent as the fiber guide extends rearward from the internal cavity of the housing to the internal cavity of the back post.
