Abstract: An adapter assembly with an adapter housing and a cross-bar. The cross-bar when depressed release one or more fiber optic connectors secured with the one or more adapter ports. The cross-bar is replaced with a return spring that secures a release tab with ribs on one side of the release tab body. The number of ribs determines the number of connectors that can be released together when the user pulls on the release tab shaft.

Abstract: An optical connector holding one or more LC-type optical ferrules is provided. The optical connector includes an outer housing, pin keep, and two pins. One pin acts as a push/pull mechanism to release the connector from the adapter. The pin keep has two side clips with one of two side clips having an alignment key on a top surface. The alignment key engages a corresponding surface in the adapter housing to aid in polarity setting of the connector with the adapter. The adapter has a panel mounting clip that contains one or more latches that engage and retain the connector in the adapter housing. The panel clips and surfaces of the connector are constructed to reduce the overall size of the connector and adapter. The adapter has a plural of internal ribs forming one or more channels.

Abstract: Optical fiber connectors configured to allow ease of change of the connector polarity by providing lockable outer housing. In an embodiment, an optical fiber connector comprises an inner housing, at least one key configured to move along the inner housing so as to change a polarity of said optical fiber connector, and an outer housing disposed around at least a portion of the inner housing and configured to slide in a longitudinal direction so as to expose at least a portion of said at least one key, wherein the outer housing includes a flexible portion configured to lock to the inner housing so as to retain the outer housing in a pulled back position relative to the inner housing. A removable alignment key is reattached to the connector to correspond to a first or second polarity.

Abstract: Low profile optical fiber connectors comprising a ferrule, a plug frame configured to receive the ferrule, and an outer housing configured to receive the plug frame. The outer housing may be configured to protrude less than about 2 mm from one end of an adapter when the low profile optical fiber connector is inserted into the adapter. The connector may include a boot sized such that the boot protrudes from the end of the adapter by less than about 15 mm. The low profile connector does not contain a bias spring to urge the ferrule forward out of plug frame housing.

Abstract: 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.

Abstract: Narrow width fiber optic connectors having spring loaded remote release mechanisms to facilitate access and usage of the connectors in high density arrays. A narrow width fiber optic connector comprises a multi-fiber connector, wherein a width of said narrow width fiber optic connector is less than about 5.25 mm, a housing configured to hold the multi-fiber connector and further comprising a connector recess, and a pull tab having a ramp area configured to disengage a latch of one of an adapter and an SFP from said connector recess. The pull tab may include a spring configured to allow the latch of one of the adapter and the SFP to engage with the connector recess.

Abstract: A multiple push-on (MPO) optical connector is provided having a ferrule configured to house multiple optical fibers and a housing having a distal end in a connection direction configured to hold the ferrule. The housing further includes a pair of proximal apertures and at least one proximal groove. A backpost has a distal end that urges the ferrule toward the distal end of the housing and a proximal end configured to receive a crimp ring. The backpost includes a pair of proximally extending latch arms that reverse latch in the proximal apertures of the housing. To strengthen the connector in side-loading environments, the backpost further includes a reinforcing rib that is received in the housing proximal groove. In a further aspect, the proximal end of the backpost may include a neck with an approximately curved side profile that, following crimping with a stepped crimp ring, results in an angled crimp.
