A fiber optic connector includes a ferrule, a ferrule adapter configured to be coupled with the ferrule, and a retention body configured to be coupled with a multi-fiber cable. The ferrule is configured to terminate a plurality of fibers of a multi-fiber cable and is configured with a cross-sectional profile smaller than a ferrule of a multi-fiber push on (MPO) connector such that the ferrule is configured to be pushed through a duct having an inside diameter smaller than a cross-sectional profile of the ferrule of the MPO connector. The ferrule adapter and the ferrule cooperate to define a ferrule interface configured to mate with ferrule of the MPO connector. The ferrule is configured to include external channels at opposing laterals sides of the ferrule. The ferrule adapter is configured to include channels that oppose the external channels of the ferrule. The channels of the ferrule adapter and the external channels of the ferrule are configured to cooperate to define a pair of bores configured to receive a pair of external pins. The bores are configured to receive a pair of pins from the mating MPO connector.

Fiber optic cable assemblies and methods of fabrication are disclosed. In one embodiment, a fiber optic cable assembly includes a fiber optic cable and a connector assembly. The connector assembly includes a connector body having a body passageway and a body aperture. The connector assembly further includes a crimp ring, a crimp body and a locking element. The crimp ring includes a first end, a second end, a crimp ring passageway, and a crimp ring aperture. The crimp body includes a crimp body passageway and one or more crimp features.

The second end of the crimp ring is crimped to the crimp body. The locking element is disposed within the body aperture and the crimp ring aperture.

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 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.

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.
