According to certain embodiments, a method comprises disposing a first nanofiber portion of a nanofiber and a first assisting fiber portion of an assisting fiber into a ferrule of a connector. A second assisting fiber portion is heated. The nanofiber and assisting fiber are moved such that a portion of the heated assisting fiber portion is disposed within the ferrule. According to other embodiments, a method comprises placing a fiber within a ferrule of a connector having a fixed point such that a fiber center is a fiber distance away from a receptacle center. The fiber distance between the fiber center and receptacle center is measured. An angular offset between the fixed point and fiber center is measured about the receptacle center. A rotation angle for the fiber distance and angular offset is determined. The ferrule is rotated relative to the connector according to the rotation angle.
