Abstract: A field installable fiber optic connector for use with polymer optical fibers includes a housing that releasably connects to another optical device. A mechanical termination assembly is located in the housing to mechanically terminate a plurality of individual fibers of the polymer optical fibers. Ferrules are supported by the housing. Each ferrule is positioned to receive one of the individual fibers from the mechanical termination assembly.

Abstract: Fiber optic network systems are implemented, at least in part, using very small form factor (VSFF) interconnect components such as VSFF duplex connector; VSFF mechanical transfer ferrule (MT) connector; VSFF duplex uniboot connector; VSFF MT uniboot connector; VSFF duplex adapter; VSFF MT adapter; VSFF duplex pluggable transceiver; VSFF MT pluggable transceiver; VSFF patch cable assembly; VSFF trunk cable; and/or VSFF breakout cable. The VSFF fiber optic network systems can define fiber breakout cabling that connects large trunk cables to many peripheral network locations. The network systems can define branches and sub-branches from a trunk cable. The network systems can define cross-connect sub-networks between sets of transceivers or adapters. The network systems can define a trunk-to-transceiver cabling assembly for connecting a trunk cable to at least 32 transceiver ports.

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 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: A micro connector kit includes first and second ferrules and first and second micro connector ferrule housings. Each first and second micro connector ferrule housing defines a cavity sized and shaped to receive a respective one of the first and second ferrules with the first and second ferrules being disposed in closely spaced relation with the respective first or second micro connector ferrule housing when in each cavity. The first and second micro connector ferrule housings can be releasably coupled together such that the first and second ferrules form an optical connection when the first and second micro connector ferrule housings are coupled together. The first and second micro connector ferrule housings have first and second connection structure for releasably coupling the first and second micro connector housings together.

Abstract: A fiber optic ferrule adapter for mating a multi-fiber optic ferrule and a multi-fiber optic connector includes a holder having a cavity where a multi-fiber optic ferrule is held therein, and a receptacle housing with an opening that allows the insertion of a fiber optic connector. The holder has a top opening for receiving the ferrule into its cavity; and two protrusions, which are respectively protruded from each interior side walls of the holder, for latching the ferrule in place inside the cavity. The holder includes a groove recessed on the interior walls of the cavity for catching a ridge on the ferrule so as to prevent any longitudinal movement of the ferrule inside the cavity. The cavity may include a slope next to an interface between the cavity and receptacle housing for allowing the sliding in-and-out of the ferrule at an angle to the top of the holder opening.

Abstract: An optical connector assembly having a connector housing with a first and second end. First end accepts a ferrule assembly, and second end accepts a retention assembly. There is a longitudinal bore from a distal to proximal end of connector. Bore accepts a POF optical fiber therein at distal end and fiber is inserted proximally until fiber bottoms-out at proximal end of ferrule. Retention body accepts one or more retention caps, or retention body contains at least one retention wing set to secure fiber to connector.

Abstract: Communication device connection assemblies are described. The sealable connection assemblies are configured to provide water-tight connections for various data transmission elements, including cables, network devices, and computing devices. The connection assemblies may be used for various data transmission protocols, such as fiber optic connections. A compression element of the connection assembly may be configured to engage and compress a sealing element against a communication cable extending through the sealable connection assembly when a tension element is coupled to the inner body, thereby forming a seal between the sealable element and the communication cable. The connection assemblies may include a retainer body configured to form a grip or retention force with a communication cable sufficient to reduce and/or eliminate any forces on the communication cable (i.e., bending and/or straight pull forces) from being transferred to and/or otherwise effecting other components of the connection assembly, such as sealing elements thereof.
