Connector assemblies having an adjustable polarity are described. A connector assembly having an adjustable polarity comprises a housing and a locking component configured to couple to the housing, the locking component including a compression element. The connector assembly further comprises a latch component configured to rotate around the locking component when the compression element is compressed to change the polarity of the connector assembly from a first polarity when the latch component is located at a first polarity position to a second polarity when the latch component is located at a second polarity position.

A fiber optic cable connector configured to be securely coupled with a cable jacket without crimping includes a connector body including a rear sleeve portion configured to receive a jacket of a fiber optic cable, a ferrule holder configured to be slidingly seated in a forward end of the connector body, a ferrule configured to be seated in the ferrule holder and to terminate an optical fiber, and a retention member having an inner diameter sized to fit into an annular groove in the jacket of the fiber optic cable and an outer diameter sized to extend radially outward of an outer surface of the jacket such that the retention member is configured to engage a surface of the rear sleeve portion of the connector body when the retention member is seated in the annular groove in the jacket so as to increase connection strength between the connector body and the jacket and to resist pull force on the fiber optic cable without crimping the connector body to the jacket.

A new fiber optic connector provides a smaller form factor by including two ferrule assemblies in a housing. The housing accepts a push-pull mechanism that allows for insertion and removal from a carrier as well as an adapter. The push-pull mechanism may also include a flexure member to return the push-pull mechanism. Polarity of the fiber optic connector may also be selected by use of the push-pull mechanism.

A multi-fiber ferrule has a main body with a top portion and a bottom portion, the top portion includes a top cut-out therein to form a first forward facing surface to engage a housing of a fiber optic connector. The top cut-out extends rearwardly from the front end. The bottom portion also has a bottom cut-out portion forming a second forward facing surface to engage the housing of the fiber optic connector, the bottom cut-out also extending rearwardly from the front end. The multi-fiber ferrule also includes an end face at a front end of the main body, and a rear face at a rear end of the main body. There is a rear central opening that extends into the main body from the rear end face and configured to receive at least three optical fibers.

A fiber optic ferrule sub-assembly for insertion into an outer housing of a fiber optic connector includes a ferrule assembly having a ferrule that forms an optical communication connection with another fiber optic device. A back housing includes a back post to be attached to a fiber optic cable. A spring is operatively disposed between the ferrule assembly and the back housing. A linkage connects the ferrule assembly to the back housing such that the spring is compressed and biases the ferrule away from the back housing prior to insertion of the fiber optic ferrule sub-assembly into the outer housing.

A crimping method includes covering an outer periphery of the back post is with reinforced fibers. The reinforced fibers are crimped to a front section of a back post. The reinforced fibers are twisted in a circumferential direction of the back post, such that the reinforced fibers extend on the outer periphery of the back post in a non-axial direction. The twisted reinforced fibers are crimped to a rear section of the back post. A crimping device includes a connector including a back post having at least one guiding rib with at least one notch. At least one crimp sleeve is used to crimp reinforced fibers of an optical fiber cable to the back post, and a portion of the reinforced fibers is gathered in the at least one notch.

A housing for a fiber optic connector includes an opening extending between a front end and a rear end, and having an integral spring stop surface between the front end and the rear end. A front section receives an elastic member into the opening from the front end and the elastic member is engageable with the integral spring stop of the housing. There is a middle section of the main body to transition optical fibers between a fiber optic ferrule and a fiber optic cable. A rear section of the main body has an outer surface to engage a crimp ring.

A fiber optic connector has a plug region at a first axial end and an anchor region at a second axial end. The anchor region includes first interlock members which protrude outwardly from a support portion. A crimp sleeve can be disposed over the anchor region of the plug connector so that a surrounding portion (e.g., a jacket and/or strength members) of the cable extends between the crimp sleeve and the first interlock members. When the plug connector is assembled, second interlock members can be formed in the crimp sleeve to extend radially into gaps between the first interlock members to enhance retention of the surrounding portion of the cable therebetween.

Fiber optic connectors having improved cable termination for attaching the strength members of a fiber optic cable to a crimp body along with cable assemblies and methods of making the same are disclosed. The fiber optic connectors and cable assemblies provide a robust cable termination so that the fiber optic jacket of the fiber optic cable is inhibited from slipping relative to the fiber optic connector when tensile force are applied to the terminated cable. The fiber optic connector allows a mechanical attachment of the strength members of the cable to a crimp body having first and second shells with respective through windows at a rear portion. One or more strength members of the cable are routed from an interior passage of the crimp body through the respective through windows so that the strength members may be secured between an outer barrel of the crimp body and a crimp band for transferring tensile forces to the strength members, rather than the cable jacket.
