An optical fiber connector with a housing configured to hold a plurality of optical fiber ferrules is selectively reconfigurable between a first configuration and a second configuration different from the first configuration. The housing can have different widths in the first and second configurations. The ferrules can have different ferrule arrangements in the first and second configurations. The optical fiber connector can be mateable with different types of receptacles in the first and second configurations. Reconfiguration can be achieved by disconnecting a rear housing from a plurality of front housings at first set of attachment points, rotating the rear housing 180° in relation to the front housings, and attaching the rear housing to the front housings at the second set of attachment points.

A multifiber ferrule has a generally forward-facing angled ferrule contact surface that is skewed with respect to the widthwise axis of the ferrule such that the angled ferrule contact surface defines a widthwise skew angle with respect to the widthwise axis. A multifiber optical connector has a connector housing assembly that holds at least one of this type of ferrule. The connector housing assembly can hold two such ferrules so that the ferrule contact surfaces are angled in opposite widthwise directions and so that a broad side of the first ferrule opposes a broad side of the second ferrule in parallel, spaced apart relationship therewith. A polarity-changeable multifiber optical connector is also provided that includes a multifiber ferrule with a generally forward-facing ferrule contact surface at an oblique angle to the longitudinal axis.

A new fiber optic connector provides a very small form factor with reduced size. The fiber optic connector may comprise a single-body housing having a front end and rear end in a longitudinal direction, two ferrules accommodated in the housing and protruding from the front end of the housing, a back housing positioned adjacent to the rear end of the housing, two springs positioned between the two ferrules and the back housing to urge the two ferrules to move forward, and a boot assembly connected to the rear end of the housing. The housing comprises a latch arm extending obliquely upwards, and the latch arm is in a depressed state when the fiber optic connector is mating with an adapter.

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.

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.

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.

The fiber optic adapter according to the present disclosure may include an adapter housing defining a channel to receive a fiber optic connector having one or more ferrules, and a first shutter and a second shutter attached to opposing sidewalls of the adapter housing. Each of the first and second shutters have a first member and a second member. The first member is configured to extend into the channel. the first members of the first and second shutters are sized and shaped to cooperatively close the channel. At least one of the first member is resiliently movable upon insertion of the fiber optic connector into the channel to open the channel. The fiber optic adapter may prevent the entry of the dust and other debris.

Fiber optic adapter

A connection system may include fiber optic connectors and an optical receptacle into which the connectors are plugged. The fiber optic connectors are constructed so that the width of the connectors is small. Eight fiber optic connectors can be received in an opening of a QSFP style transceiver.

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.

A fiber optic adapter for mating with a fiber optic connector includes an adapter housing. The adapter housing includes a wall and an opening that accepts the fiber optic connector. An optical alignment axis extends through the adapter housing and passes through the opening of the adapter housing. A guide is disposed on the wall of the outer housing. The guide comprises a cam surface located inward of the opening, facing toward the opening, and extending along an axis that is transverse to the optical alignment axis. The cam surface is arranged for engaging the fiber optic connector inserted into the opening along an insertion axis that is divergent from the optical alignment axis to drive the fiber optic connector substantially into alignment with the optical alignment axis as the fiber optic connector traverses the cam surface upon being pushed farther into the adapter housing.

A micro connector kit including a ferrule assembly, an optical sub-assembly ('OSA') and a micro connector. The ferrule assembly is coupled to an optical fiber and includes a ferrule. The OSA can receive an electric signal and transmit an optical signal or receive an optical signal and transmit an electric signal. The OSA includes a receptacle sized and shaped to receive the ferrule of the ferrule assembly to form an optical connection between the ferrule assembly and the OSA. The micro connector secures the optical connection between the ferrule assembly and the OSA. The micro connector includes a micro connector housing that forms a direct, mating connection with the OSA to secure the optical connection between the ferrule assembly and the OSA. The connection is made using only a very small space, allowing more ferrule assembly and OSA connections to be made in a smaller area.

Fiber optic micro connector

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.
