Ferrule assemblies having a lens array are disclosed. In one embodiment, a ferrule assembly includes a ferrule body and a fiber array ferrule. The ferrule body includes a first end face and a second end face, at least one cavity for receiving one or more optical fibers disposed between the first end face and the second end face, and at least one body alignment feature at an outer surface of the body. The fiber array ferrule includes a first end face and a second end face, an array of alignment holes extending between the first end face and the second end face, and at least one ferrule alignment feature at an outer perimeter of the fiber array ferrule. The second end face of the fiber array ferrule is coupled to the first end face of the body.

A connector includes a connector array of magnets having a first magnetic polarity pattern. A port includes a port array of magnets having a second magnetic polarity pattern that is complementary to the first magnetic polarity pattern. The connector is guided and aligned toward a mounted position in which the connector is retained on the port. The guiding and the aligning is through both (i) attraction when the connector is properly aligned to the port and (ii) repulsion when the connector is improperly aligned to the port. The port further includes a securing magnet configured to be activated when the connector reaches the mounted position, to magnetically secure the connector to the port.

A ferrule-based fiber optic connectors having a connector assembly with a ferrule having an integral ferrule insertion stop for limiting the insertion of the ferrule into a ferrule sleeve are disclosed. In one embodiment, the fiber optic connector comprising a connector assembly, a connector sleeve assembly and a female coupling housing. The connector assembly comprises a ferrule and a resilient member for biasing the ferrule forward and the connector sleeve assembly comprises a housing and a ferrule sleeve, where the ferrule of the connector assembly is at least partially disposed in the ferrule sleeve when assembled. The ferrule has an integral ferrule insertion stop that limits the depth that the ferrule may be inserted into the ferrule sleeve.

An optical fiber connection mechanism includes a pair of connectors and a split sleeve that are used in an endoscope. The connectors include respective ferrules, an end of a single-mode optical fiber and a collimator lens is mounted in each ferrule, and the collimator lens is disposed at the tip of the single-mode optical fiber. The optical fiber connection mechanism is configured so that when the ferrules are inserted into ends of the split sleeve, the collimator lenses face each other with a gap therebetween and the single-mode optical fibers are optically connected to each other. The ferrules are loosely fit in the corresponding connectors to be displaceable within a predetermined range in the direction along the optical axis of the single-mode optical fibers.

In accordance with an example embodiment, an apparatus is disclosed. The apparatus includes an adapter, a coupler, and a sleeve. The coupler is configured to be connected to the adapter. The coupler includes a lever. The sleeve is connected to the coupler. The lever is configured to deflect when the coupler is rotated relative to the sleeve.

Devices such as terminals comprising connection ports with associated securing features and methods for making the same are disclosed. In one embodiment, the device comprises a shell, at least one connection port, and at least one securing feature. The at least one connection port is disposed on the terminal with the at least one connection port comprising an optical connector opening extending from an outer surface of the terminal to a cavity of the terminal and defining a connection port passageway. The securing feature is associated with the connection port passageway and is biased by a resilient member having a predetermined pre-load restoring force to the retain position.

A fiber optic adapter includes a shell body defining an inner space, a dividing wall dividing the inner space into two receptacles, an installation seat, and a securing seat. The installation seat and the securing seat are respectively located in the receptacles. The securing seat includes a plurality of base walls connected in pairs, a plurality of pairs of clamping walls, and a plurality of clenching walls. Each base wall cooperates with a respective pair of the clamping walls and a respective clenching wall to form a ring-shaped structure, with each adjacent two of the base wall, the pair of clamping walls and the clenching wall defining a gap therebetween.

An optical fiber connector includes an outer housing, a rear member sleeved on a rear end of the outer housing, a polarity key, and a release pull lever. The polarity key includes a body part extending from the rear member and located on one side of the outer housing, a latching part formed with a cutout and having a first sloping surface, and a locking protrusion extending from the latching part. The release pull lever is disposed on the outer housing and has a driving portion protruding into the cutout and being in sliding contact with the first sloping surface, such that rearward movement of the release pull lever drives the locking protrusion to move close to the outer housing.

A multi-fiber, fiber optic connector may include a reversible keying arrangement for determining the orientation for plugging the connector into an adapter to thereby allow for a change in polarity of the connection to be made on site. The connector housing may be configured to engage with a removable key that may be engaged with the housing in at least two different locations to provide the plug-in orientation, or the housing may have slidably displaceable keys movable between multiple positions on the housing.

A dust cap includes a cap body and a pair of opposing latches. The cap body is adapted to cover a connectorized end of a fiber optic connector and cable assembly when the connectorized end is inserted through an opening of an interior of the cap body. The cap body further includes an opposing pair of resilient walls. The pair of opposing latches each include latching features that extend outside of the interior of the cap body. The pair of opposing latches each further include a mounting portion mounted to a respective one of the opposing pair of resilient walls. The dust cap may further include a pulling interface. The pulling interface may be adapted to attach to a pulling member and may be positioned at a tapered nose of the cap body. The dust cap may thereby be a cable pulling cap and may pull a fiber optic connector and cable assembly through conduits and other narrow passages. A pair of opposing pulling halves may enclose the cable pulling cap or the dust cap without a pulling interface and at least a portion of the connectorized end of the fiber optic connector and cable assembly.
