The present disclosure relates to a ruggedized female fiber optic connector designed to reduce cost. In one example, features of a fiber optic connector and a fiber optic adapter are integrated into one assembly. In another example, a female ruggedized optic connector is provided with a simple structure having a pre-assembled ferrule alignment sleeve including a ferrule.

An expanded beam (EB) optical connector. In some embodiments, the EB optical connector includes: a rigid, hollow, straight contact tube having a centerline axis; and a collimator assembly having an optical axis and comprising an optical fiber and a collimating lens, wherein the centerline axis of the contact tube is at least substantially aligned with the optical axis such that collimated light produced by the lens from light exiting the fiber travels though the contact tube and the loss of light caused by misalignment of the axes is not more than 2 dB.

A fiber-optic connector housing (50) and cable (20, 20) are attached together by an anchor (100, 200). The anchor includes a one-piece main body, a passage (110, 210), and an injection port (130, 230). The passage extends between first (102, 202) and second ends (104, 204) of the anchor. Strength members (40, 40) of the cable are secured within the passage by a bonding material (90) and are thereby anchored to the connector housing. A proximal end (54) of the connector housing includes first (60) and second housing components (70) which capture the anchor. The passage passes through an optical fiber (30) of the cable. The passage includes first (120, 220), second (170, 270), and third portions (180, 280). The first portion radially positions the optical fiber. The second portion receives the bonding material and the strength members. The third portion receives a jacket (26, 26) of the fiber optic cable. The injection port delivers the bonding material to the passage. The anchor may further include retention tabs (150) that fit within corresponding receivers (62, 72) within the connector.

A fiber optic adapter assembly is provided with a floating adapter module. The adapter assembly includes a housing, an adapter module, and a single biasing member disposed in the housing and concentrically aligned with the adapter module. The single biasing member can bias the adapter module in a direction toward an end of the housing and be compressible in the opposite direction toward the other end of the housing.

This optical connector includes a ferrule, a plug frame, and an elastic member. The ferrule holds a glass fiber of an optical fiber. The plug frame receives the ferrule. The elastic member holds, with a first length, the ferrule in a first position in the plug frame, or holds, with a second length shorter than the first length, the ferrule in a second position in the plug frame. When the ferrule is in the first position, the ferrule and the plug frame are in contact with each other via the tapered surface, and the pivotal movement of the ferrule to the plug frame is restricted. When the ferrule is in the second position, the ferrule is not in contact with the plug frame and is pivotable to the plug frame, and the ferrule is in a floating state.

This application provides a pre-connector and a communications device. The pre-connector includes a connector component and an outdoor component. The connector component includes a ferrule base and a ferrule that is slidable relative to the ferrule base. The ferrule base is configured to fasten the optical cable, and the ferrule is connected to an optical fiber that is of the optical cable and that is inserted into the ferrule base. In this way, the optical fiber can be connected to the communications device by using the ferrule. The outdoor component includes: a spindle that is sleeved on the ferrule base and that is fastened to the ferrule base; and a handle sleeve sleeved on the spindle. The outdoor component is used as a connecting piece to be detachably fastened and connected to the communications device, so as to provide a locking force used when the communications device is connected.
