Abstract: A cleaning stick guide for an optical housing having ferrules therein. The cleaning stick guide includes a guide housing having a proximal end and a distal end. The guide housing includes an insert portion sized and shaped to be inserted into the optical housing. The insert portion defines the distal end of the guide housing. The guide housing includes guide passageways. Each guide passageway extends from the proximal end to the distal end. Each guide passageway is arranged in the guide housing to align with one of the ferrules in the optical housing when the guide housing is inserted into the optical housing. Each guide passageway is sized and shaped to receive a cleaning stick and to guide the cleaning stick to said one ferrule for cleaning the ferrule.

Abstract: An integral fan-out connector assembly for fiber optic cables includes a connector housing that provides an integrated fan-out housing and connection adapter. The fan-out connector housing may be configured with a variety of cable adapters, and may be installed as a ‘plug and play’ type solution where it will be ready to accept a feed cable for use when needed. A bracket may support the fan-out system on a support structure as a pole. The bracket can facilitate plug-and-play use of the fan-out system.

Abstract: Connector assemblies are described herein. For example, a connector assembly including: a housing configured to accept a first ferrule and a second ferrule. The connector assembly may also have a push/pull clip that is configured to depress a protrusion that rotates down a connector device to remove the connector assembly from an adapter. The push/pull clip is integrated with a cable boot assembly that allows a user to apply a distal force to remove or insert the connector assembly into the adapter housing. The push/pull clip is configured for use to release a MPO and LC connector type from an adapter.

Abstract: An optical connector holding one or more optical ferrule assembly is provided. The optical connector includes an outer body, an inner front body accommodating the one or more optical ferrule assembly, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four optical ferrule assembly are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight optical ferrule assembly are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A receptacle can hold one or more connector inner bodies forming a single boot for all the optical fibers of the inner bodies.

Abstract: A fiber optic connector includes a housing having an internal cavity and a front opening. A back post has an internal cavity, a front opening and a rear opening. The back post is operatively connected to the housing so that the internal cavity of the back post communicates with the internal cavity of the housing. At least two ferrules are disposed at least partially within the internal cavity of the housing and are exposed through the front opening of the housing. Each ferrule has a cylindrical shape and includes a flange. Each ferrule couples to an optical fiber. A fiber guide is coupled to each ferrule. Each fiber guide receives one of the optical fibers. Each fiber guide extends rearward from the ferrule. Each fiber guide extends in the internal cavity of the housing and the internal cavity of the back post. Each fiber guide is bent as the fiber guide extends rearward from the internal cavity of the housing to the internal cavity of the back post.

Abstract: A fiber optic connector deploys a latch lever release with an elastic rib. When the latch lever release is depressed down or toward the optical axis of the connector, a hook seated within a recess of the connector outer housing, the hook is lifted out of the recess thereby allowing the connector to be removed from the adapter port. A pivot point is formed between the main body of the latch lever release and the connector outer housing. Depressing the latch lever release distal of the pivot point at the trigger portion displaces the hook from the connector thereby allowing the user to remove the connector from a receptacle port, such as an adapter port.

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.
