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.

Abstract: A fiber optic adapter assembly includes an adapter body, a spring clip and a retention cap attached to the adapter body enclosing each of the spring clip and two shutters. The adapter body has a main opening and a plurality of pivot arms extending away from the main opening and two latch arms, each of the latch arms disposed between a pair of the pivot arms causing gaps between the latch arms and the pivot arms, which are sealed by the retention cap. The spring clip has a plurality of fingers moveably contacting each of shutters, which pivot between a first and second position.

Abstract: An adapter holds a multi-fiber ferrule in position to mate with a multi-fiber ferrule in a fiber optic connector. The adapter includes an adapter body that has a first opening in a first side of the adapter body that receives the multi-fiber ferrule and a second opening in the second side of the adapter body to removably receive the fiber optic connector. The adapter also includes a pair of latches connected to the adapter and disposed adjacent the first opening to engage and hold the multi-fiber ferrule in the adapter. The pair of latches are connected to the adapter body along longer edges of the first opening and extend in a direction away from the first and the second openings, the pair of latches having a terminal end and a non-uniform thickness between the adapter body and terminal ends.

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.

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: An assembly of two fiber optic ferrules allows for the mating of a CWDM fiber optic ferrule with a non-CWDM fiber optic ferrule. The CWDM fiber optic ferrule has optical fibers that carry optical beams with at least two different wavelengths, which the non-CWDM ferrule has optical fibers that carry only one wavelength. The CWDM fiber optic ferrule and the non-CWDM fiber optic ferrule have optical fibers that are inserted along parallel axes. The non-CWDM fiber optic ferrule has a lens pitch that matches the CWDM ferrule.

Abstract: A dust plug for use in a pre-populated adapters has a main body having a top wall, a bottom wall, and two opposing side walls extending between the top wall and bottom wall. The dust plug also includes at least one pair of latches in a front portion of the main body and each of the at least one pair of latches may have an increased thickness at a forward end thereof. The area of increased thickness is sized to engage a receptacle in an inner surface of the housing when the dust plug is attached to the housing. Other versions contemplate not having the increased thickness. The dust plug preferably includes a grip at the back end.

Abstract: A new fiber optic ferrule has an alignment structure on a surface through which light passes. The alignment structure is preferably in the shape of a dog bone, allowing the alignment structure to align the fiber optic ferrule in a receptacle while reducing the influence of temperature on the alignment.

Abstract: A modified housing and adapter prevent unwanted contact during the mating of fiber-optic connectors by using positive features and negative features in the housing, while the modified adapter presents negative features and positive features in mating of the two structures.

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 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: An adapter receives a multi-fiber ferrule in opposing ends, the multi-fiber ferrules have different formats, end-face configurations and areas. The ferrules may be disposed in a fiber optic connector or a sleeve. In at least one embodiment, a MT ferrule is optically mated to a TMT ferrule, the MT ferrule being disposed in an MPO connector while the TMT ferrule is disposed in a VSFF connector.

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 combination of a fiber optic ferrule and a fiber optic ferrule holder includes a fiber optic ferrule with a pair of guide pins movable between a non-mating position and a mating position via a spring mechanism. The fiber optic ferrule includes at least one cut-out with a ferrule stop surface associated therewith. The ferrule holder has a central opening in the body and two holder extensions extending longitudinally and forward of the fiber optic ferrule holder, each of the holder extensions include a rear stop surface configured to engage a respective ferrule stop surface on the fiber optic ferrule.

Abstract: 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.

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.
