An adapter to mate fiber optic ferrules to respective fiber optic ferrules in a fiber optic connector housing includes a main body having ferrule-side openings and connector-side openings to receive the fiber optic connectors. The adapter includes columns that extend between a top side and a bottom side of the main body, a plurality of triggers attached to the adapter, each of the plurality of triggers having a pair of trigger legs, the trigger legs positioned inside respective columns on opposing sides. There is also a holder extension groove oriented longitudinally in each column and configured to receive a holder extension of a fiber optic ferrule holder and a pair of ferrule stop pedestals on each column on opposite sides of each holder extension groove configured to seat the fiber optic ferrule when the fiber optic ferrule holder is fully inserted into the adapter.

A pin claim has a forward pin clamp portion having two flexible members extending rearwardly therefrom on opposite lateral sides of an opening of the forward pin clamp portion, and a rearward pin clamp portion movably engaged to the forward pin clamp portion and configured to engage the spring when assembled in the fiber optic connector. The rearward pin clamp portion has two recesses to respectively receive the two flexible members from the forward pin clamp portion, wherein each of the two flexible members is movable between a first position and a second position within each of the two recesses, and wherein the forward pin clamp portion and the rearward pin clamp portion are inseparable from one another.

A combination of a carrier and a dust cap for at least two fiber optic connectors includes a carrier, a dust cap, and a pulling structure adjacent the closed end of the dust cap and extending away from the open end, at least one attachment mechanism to couple the dust cap to the carrier, wherein the at least one attachment mechanism is in a stressed position when the carrier and the dust cap are secured to one another.

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 flexible push-pull boot extends between a front end and a rear end, a rear portion has a spine and a plurality of ribs extending from the rear end toward the front end. There is also a middle portion from which a plurality of front extensions extend. At least one of the front extensions has an inwardly extending projection on an inside portion of the front extensions to retain a housing therebehind.

A fiber optic ferrule push includes a main body extending between a front end and a rear end, the main body having a central opening extending between the front end and the rear end to receive a plurality of optical fibers therethrough, a front facing surface configured to engage a rear surface of a fiber optic ferrule, and at least one projection extending outward from the main body to engage a housing configured to receive the fiber optic ferrule, the fiber optic ferrule push may also include a key extending outward from a surface of the main body. The fiber optic ferrule push may be paired with a fiber optic ferrule in a fiber optic assembly.

A fiber optic connector has a crimp body that allows for a heat shrink tube to be abutted to the crimp band used with the crimp body or dispose underneath the crimp band to allow for the use with a VSFF fiber-optic connector.

A fiber optic ferrule has a main body with a top surface and a bottom surface and extends between a front end and a back end. The front face includes a recessed portion with a plurality of optical lenses. The front face is configured to allow for the plurality of lenses to be on an angle relative to the front face and the fiber optic ferrule will have not any undercuts and allow the fiber optic ferrule to be ejected from a mold without engaging any portions of the mold.

A fiber optic connector assembly is mated with a bracket on a printed circuit board at one end and inserted into a backplane adapter that is adjacent a backplane. In particular a spring push in slidingly attached to the bracket and also to the housing of the fiber optic connector assembly. The housing of the fiber optic connector assembly insertable into the backplane adapter using passive alignment features. A fiber optic ferrule in the fiber optic connector assembly is biased in a forward direction by a spring in the spring push. At the same time the spring allows for movement of the spring push within the housing to allow for movement of the printed circuit board relative to the backplane adapter.
