A new boot for a fiber optic connector has a ribbed back portion, a center portion, and a forward extending portion that can be used to insert and remove the fiber optic connector to receptacle. The ribbed back portion has grasping elements and is connected to the center portion. The center portion is removably connected to a crimp body that is in turn connected to the connector housing. The front extension is connected to the fiber optic connector and also provides a keying feature depending on the side of the fiber optic connector on which it is installed.

Flexible push-pull boot

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 small form factor dust cap for a fiber-optic connector includes a main body having a front portion, a middle portion, a rear portion, and an internal opening extending within the main body from the rear portion toward the front portion, the main body formed by two long side walls joined by a short top wall and an oppositely placed short bottom wall, a pair of cutouts in each of the respective two long side walls and located nearer to one of the short top wall and the short bottom wall, an extension extending rearwardly from the middle portion and having a free end, and an engagement mechanism at the free end of the extension to engage a housing of the fiber optic connector. The dust cap is also combined with a small form factor fiber optic connector.

A fiber handling tool has a cover to engage optical fibers placed in the fiber handling tool. There may be more than one cover and the covers have at least two elastic elements. There are at least two elastic elements that cooperate to hold the optical fibers and/or cable in place and another elastic element may be used with a door lock that is rotatably attached to the cover. There are also structures for managing the routing of the optical fibers within the tool.

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 and a guide pin clamp allows for changing guide pins in the field. The guide pin clamp has a forward clamp portion, a rearward clamp portion configured to engage the biasing spring and a guide pin retaining plate. The forward clamp portion and the rearward clamp portion move relative to one another to also move guide pin retaining plate from a first position to a second position to allow for the removal or insertion of guide pins.

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 tool is used for inserting and removing an MT-type fiber optic ferrule from an adapter. The tool includes a handle having one or both of an insertion portion and a removal portion. An insertion head is movably coupled to the insertion portion of the handle. A removal head is movably coupled to the removal portion of the handle. The handle has opposing ends for the insertion portion and the removal portion. The handle may have other configurations. A sliding lock may be used to lock the rotatable insertion portion and rotatable removal portion in a fixed position relative to the handle.

Combination tool for fiber optic ferrule insertion and removal

A fiber optic ferrule and a fiber optic connector housing make contact only along two sides of the fiber optic ferrule when in an unmated condition. One of the fiber optic ferrule and the fiber optic connector housing have been modified such that only two of the surfaces engage one another. The shoulders can be shortened, lengthened, or have a projection added to the current surfaces.

An adapter with novel alignment features engages alignment features on a plug, providing general alignment of the ferrule holders and ferrules in the plug. After the plug engages the adapter, the ferrule holders engage a second set of alignment features in the adapter to provide fine alignment for the ferrules.
