Abstract: A preconnectorized outdoor cable streamlines the deployment of optical waveguides into the last mile of an optical network. The preconnectorized outdoor cable includes a cable and at least one plug connector. The plug connector is attached to a first end of the cable, thereby connectorizing at least one optical waveguide. The cable has at least one optical waveguide, at least one tensile element, and a cable jacket. Various cable designs such as figure-eight or flat cables may be used with the plug connector. In preferred embodiments, the plug connector includes a crimp assembly having a crimp housing and a crimp band. The crimp housing has two half-shells being held together by the crimp band for securing the at least one tensile element. When fully assembled, the crimp housing fits into a shroud of the preconnectorized cable. The shroud aides in mating the preconnectorized cable with a complimentary receptacle.

Abstract: An optical ferrule assembly is disclosed. The optical ferrule assembly comprises a ferrule body, a notch part, a retainer and an annular member. The ferrule body includes an optical fiber loading hole extending therethough in a longitudinal direction. The notch part is formed in the ferrule body and has a flat surface which receives the optical fiber loading hole. The retainer is arranged in the notch part and has a lower abutting surface opposing to the flat surface and an inclined abutting surface formed on one end side of the lower abutting surface. The annular member fits on an outer periphery of the ferrule body. When the annular member is brought into contact with a portion of an outer peripheral surface of the retainer on one end side thereof, the inclined abutting surface is opposed to the flat surface, and the lower abutting surface is inclined to the flat surface and separated from the flat surface. When the annular member is brought into contact with the whole of the outer peripheral surface of the retainer, the inclined abutting surface is inclined to the flat surface and separated from the flat surface, and the lower abutting surface is opposed to the flat surface.

Abstract: A fiber optic connector including a ferrule surrounding an optical fiber and a hub engaging the ferrule. The hub includes a front portion having first and second opposing surfaces and first and second tapered regions extending from the first and second opposing surfaces to a front face. A housing includes an anti-rotation seat configured to engage the first and second opposing surfaces, the anti-rotation seat including parallel first and second contact lines positioned at a front of the anti-rotation seat. A spring within a chamber of the housing biases the ferrule through a bore in the front of the housing. The first tapered region of the hub engages the first contact line and the second tapered region engages the second contact line when the hub and ferrule are in a first rotational position so that the optical fiber is maintained at a known orientation with respect to the connector.
