Abstract: A fiber optic connector has a housing including separately formed housing portions configured to be connected to each other to cooperatively define an enclosure. A first of the housing portions has a latch formed integrally with the first housing portion. A fiber optic ferrule is located in the enclosure of the housing. The housing portions each define a back post element which together define a back post of the housing configured for securing a cable to the housing.

Abstract: Reduced-profile connection components are described. The reduced-profile connection components are configured to connect various data transmission elements, including cables, network devices, and computing devices. A non-limiting example of a connection component includes a fiber optic connection component, including connectors, adapters, and assemblies formed therefrom. In some embodiments, the connection components may include mechanical transfer (MT) and multi-fiber push-on/pull-off (MPO) connection components, such as MT ferrules and MPO adapters. The reduced-profile connection components configured according to some embodiments have a smaller profile and/or require less parts to achieve a connection compared to conventional connection components. In some embodiments, the reduced-profile connection components may be used with conventional connection components. For example a reduced-profile connector may use a conventional MT ferrule to establish a connection within a conventional MPO adapter.

Abstract: Lockable connector and adapter assembly with a rear body having a shield to prevent unlocking of the connector from the adapter port unless the connector is unlocked with a key configured for the connector. The lockable connector is a MPO connector with a slidable outer housing configured to receive a key latch arm of specific configuration to unlock the MO connector from the adapter port. The key latch arms or separate keys form the combination unlocking the MPO connector from the adapter port.

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.

Abstract: An optical fiber connector includes an optical fiber ferrule and a single-piece housing in which the ferrule is received. The housing can be installed in an adapter to make an optical connection. A rotational locking mechanism has a rotor mounted on the housing for rotation with respect the housing about a rotational axis. The rotor can be rotated between a locked position and an unlocked position. The rotational locking mechanism is configured to inhibit the housing from being withdrawn from the adapter in the locked position of the rotor and to permit the housing to be withdrawn from the adapter in the unlocked position, and further comprising a guide pin, wherein the housing comprises an integral guide pin retainer configured to hold the guide pin in place on the housing.

Abstract: A fiber optic adapter assembly reduced in size from a SFP footprint to a SC footprint to accommodate a first fiber optic connector on a first side within one or more ports, and a second fiber optic connector on a second side within one or more ports. The first fiber optic connector is a duplex fiber optic connector with an overall length of about 50 mm and the second fiber optic connector is a behind-the-wall connector with an overall length of about 15 mm thereby reducing the overall length of a connector and adapter assembly for increasing optical fiber density.

Abstract: A dust shutter plate biased by a spring plate closed within a port of an adapter assembly with one or more receptacle ports configured to received and secure a fiber optic connector. The dust shutter plate may be coated with a cloth or gel to reduce light transmission losses or both. The angle of the spring plate ensures the plate coated makes contact with the ferrule endface to remove debris and coat the optical fibers at the endface. And if not a coated dust plate, the spring is angled to ensure the ferrule endface does not contact the dust shutter plate surface and damage the optical fiber therein. The dust shutter plate may have a plural of grooves on the connector facing side of the shutter plate.

Abstract: A multi-fiber, fiber optic connector is interchangeable between a male connector and a female connector by including a pin retainer having a releasable retention device configured to lock the pins in place within the retainer. The retention device may be opened, for example, with a release tool, to free the retention pins for removal of the pins. A method for switching a connector between a male connector configuration and a female connector configuration may be possible as a result of the releasable retention configuration.

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.
