Abstract: A passive optical alignment coupling between an optical connector having a first two-dimensional planar array of alignment features and a foundation having a second two-dimensional planar array of alignment features. One of the arrays is a network of orthogonally intersecting longitudinal grooves defining an array of discrete protrusions that are each in a generally pyramidal shape with a truncated top separated from one another by the orthogonally intersecting longitudinal grooves, and the other array is a network of longitudinal cylindrical protrusions. The cylindrical protrusions are received in the grooves, with protrusion surfaces of the cylindrical protrusions in contact with groove surfaces and the top of the discrete protrusions contacting the surface bound by the cylindrical protrusions. The optical connector is removably attachable to the foundation to define a demountable coupling, with the first array of alignment features against the second array of alignment features to define an elastic averaging coupling.

Abstract: An optical connection system for use with a receptacle and an optical cable assembly includes an adapter and connector. The adapter has an adapter latch element, and the connector has a connector latch element. A delatch actuator with a delatch arm is disposed on the connector housing for movement from a locking position to an unlocking position. One of the adapter latch element and connector latch element is a bendable latch hook and the other is a locking channel. When the connector housing is mated with the adapter, the delatch arm allows the bendable latch hook to latch with the locking channel in the locking position and unlatches the bendable latch hook from the locking channel as it moves to the unlocking position. An actuator lock movably supports a blocking member on the connector for selectively blocking the delatch actuator from moving to the unlocking position.

Abstract: A multi-polarity fiber optic connector is configured to provide a plurality of connector polarity options. Two LC connectors are grouped together using a duplex cable boot assembly which is secured over a backpost extending from a plug frame of each LC connector. Each LC connector has a release latch attached to the outer surface of the plug frame. A dual release latch has a hook that secures the dual release latch to the duplex cable boot. The dual latch release is configured to depress each LC connector latch release together. To change the duplex LC connector from a first polarity to a second polarity, a user pulls on one of the two cable boots that makes up the duplex cable boot assembly and then rotates each LC connector housing, or the user pulls on the dual latch release and then rotates each LC connector housing. User rotates each LC connector housing 180 degrees about a longitudinal axis of the LC connector to change the connector polarity from a first polarity to a second polarity where the first polarity is opposite the second polarity.

Abstract: A fiber optic adapter for mating a multi-fiber optic ferrule connector and a multi-fiber optic connector. An engagement device may be integrated or molded as part of adapter receptacle at either end. The engagement device secures the multi-fiber connector. The adapter may be two-piece with a first portion detachable from a second portion, the first portion housing one or more integrated engagement devices and the second portion housing one or more replaceable engagement devices, or a receptacle configured to secure a latch configured on an outer housing of a connector. Receptacle may further contain a plural of engagement devices formed as a unitary engagement device. The receptacle has a gap configured to accept the integrated engagement device. A ferrule flange assembly configured to front load into a connector housing. A connector housing with a top and a bottom stabilizer for the fiber optic connector with an adapter port.

Abstract: In an ingress-protected fiber optic connector assembly, an optical fiber plug mates with a receptacle at a bulkhead adapter and an ingress-protected housing assembly couples to the bulkhead adapter to enclose the optical fiber plug. The ingress-protected housing includes an outer housing and a compressible cable seal. The outer housing is rotatable to advance the outer housing, simultaneously compressing the compressible cable seal and fastening the housing assembly to the bulkhead adapter. The outer housing can have a plurality coupling positions at which the cable seal is compressed with a different amount of compression force. A non-sealing cable clamp can transfer tension on the cable to the bulkhead adapter.

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: An in-line dust shutter formed as part an adapter. A hinged dust shutter assembly is secured to an adapter wall. A shutter plate covers an opening formed at either end of the adapter to prevent debris from entering the adapter and distorting the light signal between opposing fiber optic connectors. The shutter plate extends at angle alpha from a rotational axis. The shutter plate is biased closed by a bias spring place about a pin of the rotational axis.
