Abstract: A method for terminating a fiber optic ferrule included applying a force to a fiber optic ferrule while simultaneously holding the optical fibers. The fiber optic ferrule uses epoxy to hold the optical fibers, the epoxy can be either heat or light cured. The force is applied through a pusher that engages a cap on the front end of the fiber optic ferrule.

Abstract: 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.

The assembly includes a second multi-fiber ferrule exclusively connected to the optical receiver via a second set of at least two optical fibers operable to transport respective optical signals to the optical transmitter. The first set of at least two optical fibers is separate from the second set of at least two optical fibers.

Abstract: A retaining mechanism engages springs in a fiber optic connector to prevent movement of the springs relative to the fiber optic ferrules and the housing during curing of an epoxy inserted into the fiber optic connector. The retaining mechanism may be removably attached to the housing of the fiber optic connector. It may be inserted from a rear end of the fiber optic connector or disposed around an outside portion of the housing. The retaining mechanism may also be integral with an inside surface of the housing.

Abstract: 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.

The fiber optic ferrule push may be paired with a fiber optic ferrule in a fiber optic assembly.

Abstract: 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.

Abstract: A two-piece fiber optic connector and a corresponding two-piece adapter allow for the tripling of the optical fibers that can be used with a standard fiber-optic cassette. The two-piece fiber optic connector has a fold-over latch to engage the adapter. The two-piece adapter has at least one latch to engage the standard fiber-optic cassette to retain the two-piece adapter and the fiber optic connectors in the adapter within the cassette. This allows for the retrofitting and/or continued use of the standard fiber-optic cassette.

Abstract: 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.

Abstract: A fiber optic ferrule receiver includes a main body that has an opening extending between the front end and the rear end and being defined at least by a portion of internal surfaces of the four sides. A first side in the opening has first tapered surface and a second tapered surface, the first tapered surface reducing the opening between the rear end and a first position and the second tapered surface increasing the opening between the first position and the front end. There is also a second side in the opening and across the opening from the first side, the second side has a third tapered surface and a fourth tapered surface, the third tapered surface reducing the opening between the rear end and a second position and the second tapered surface increasing the opening between the second position and the front end.

Abstract: A multi-fiber ferrule has lenses that have different prescriptions to disperse the light emitted from the multi-fiber ferrule. Alternatively, the lens for each individual optical fiber can be moved relative to the optical fiber or the optical fiber opening in the multi-fiber ferrule to cause the laser beam exiting the multi-fiber ferrule to be redirected into a structure that absorbs or blocks the laser.

Abstract: An optical connector assembly (OCA) includes a connector housing to maintain alignment between optical components housed within the OCA and photoelectric converters on an optoelectronic substrate (OES) assembly. The optical components include a ferrule and an optical cable. The ferrule is optically coupled to the optical cable. The OCA includes a ferrule holder to hold the ferrule within the OCA, and a spring located between the connector housing and the ferrule holder. The spring is to apply a separating force between the ferrule holder and the connector housing. The OCA includes a gasket coupled to the connector housing. The coupling of the connector housing to a socket compresses the gasket to provide a seal between the connector housing and the socket.

Abstract: 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.

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.

Abstract: 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.

Abstract: 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.
