A multi-fiber fiber optic connector is provided having features that allow for changeability with respect to gender. A pin retention structure is configured to retain a pair of alignment pins and includes a pin-holder body with a pair of pin openings and a U-shaped spring clip. The spring clip including a base portion and two opposing legs, and is movable between a pin retaining position and a pin release position. When the spring clip is in the pin retaining position, the two opposing legs engage with outer sides of each of the alignment pins, and when the spring clip is in the pin release position, the base portion flexes inwardly and the two opposing legs disengage with the outer sides of each of the alignment pins.

The disclosure provides an optic fiber connector, including a ferrule, a holder, a connector body having a plurality of first locking slots, a spring sleeved onto the holder, and a retainer having a plurality of locking hooks. The ferrule is assembled to the holder. The spring, the holder, and the ferrule are received in a space formed between the retainer and the connector body by locking the locking hooks with the locking slots respectively, wherein the spring is compressed by locking such that the retainer, the holder, the spring, and the connector body are abutted with each other.

A multi-fiber, fiber optic connector is provided having a housing having a first end for receiving a multi-fiber fiber optic cable and a second end having openings for the fibers from the cable. First and second keys for setting the polarity of the fibers within the connector located on opposing sides of the connector. The connector has either one of guide pins or guide pin receiving holes for guiding the connection with a second connector. The keys are movable between a first active position and a second retracted position, such that when one of the keys is in the first active position, the fibers are presented within the connector in a first polarity and when the second key is in the first active position, the fibers are presented within the connector in a second polarity reversed from the first polarity.

A fiber optic connector along with a tool allows for the changing of the polarity of the fiber optic connector. Keys may be installed in both the top and the bottom of the fiber optic connector, one in a first position and the other in a second position. Using the tool in one back-and-forth motion, the polarity of the fiber optic connector can be changed. The keys have a configuration that resist an incorrect insertion and provide better retention of the keys in the correct configuration due to a better retention force.

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.

Fiber optic terminals having one or more connector ports configured for receiving fiber optic connector having a latching trigger used as a connector securing/release mechanism connectors are disclosed. The fiber optic terminals comprise an actuator along with a flexible tab that are associated with the respective connector port of the shell of the fiber optic terminal. The actuator may translate to engage the flexible tab for engaging with the latching trigger of the fiber optic connector for allowing the release of the fiber optic connector from the connector port. An example of a fiber optic connector having a latching trigger used as a connector securing/release mechanism are LC connectors, but the terminal concepts may be used with other suitable connectors such as SC connectors having a latching trigger.

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and, a part of the rear portion of the housing comprises a round cross-section and a part of the front portion of the housing comprises a non-round cross-section with a transition region disposed between the rear portion and the front portion.

The present disclosure relates to ruggedized push-pull fiber optic connection system. The fiber optic connection system includes a push-pull connector that is adapted to be latched within and sealed with respect to a connector port.

An optical fiber connector sub-assembly for an optical fiber connector including a ferrule configured to hold an optical fiber therein along an axis of the connector, a ferrule holder configured to hold the ferrule at a front portion of the connector, a ferrule housing including a front portion configured to slidingly receive the ferrule holder and a rear portion terminating a fiber optic cable that includes the optical fiber, and an inner housing configured to fixed coupled with the ferrule housing. The ferrule is configured to terminate the optical fiber. The ferrule holder, the ferrule housing, and the inner housing are configured to be rotatably fixed to one another. The ferrule holder is configured to slide axially relative to the inner housing.

A ferrule can be assembled in the field. A ferrule collar has a non-circular, in particular polygonal outer contour. A corresponding coding region of a ferrule housing is arranged in a portion of a contact chamber on a cable-connection side and has a non-circular, in particular polygonal cross section, in which the ferrule collar is held with a form fit over the entire spring displacement path. The ferrule spring acts on the ferrule collar over the entire displacement path. As a result, the ferrule is secured against rotation about its axis by a high holding force, which makes it easier for a fibre-optic cable to be screwed on. The structural form is particularly well-suited for use in a plug-in connector module.
