Systems, assemblies and methods for deploying an optical fiber through a duct to a customer premises. A blowable section of the optical fiber is blown through the duct. A non-blowable section of the optical fiber is coupled to a trail end of the duct. The non-blowable section can be terminated with a hardened or ruggedized connector. The optical fiber, including both the blowable and non-blowable sections, can be wound around a spool for easy payout of the blowable section.

The present invention discloses a fiber optic connector comprises: a ferrule assembly; a spring seat provided behind the ferrule assembly; and a spring provided between the ferrule assembly and the spring seat. The spring seat has a receiving chamber having an insertion port through which a portion of the ferrule assembly is inserted into the receiving chamber; wherein the ferrule assembly is pre-assembled into the receiving chamber of the spring seat in a way that the ferrule assembly is held to be movably engaged with the spring seat. The spring is fitted and compressed in the receiving chamber. As a result, the ferrule assembly, the spring seat and the spring are pre-assembled into an integral assembly before being inserting into a connector housing. All components of the connector except for the housing may be smoothly pulled through a small long pipe as a whole. After being pulled through the pipe, all components of the connector except for the housing may be easily and quickly inserted into the housing as a whole at one time.

Fiber optic connectors, including SC and MPO connectors that include a strain relief boot operably coupled with a release mechanism for releasing the connector from an adapter or other termination device or receptacle. The strain relief boot can be operably coupled to move axially together with the outer housing of the connector.

In accordance with the following description, an optical communication connector includes a ferrule having retractable alignment pins that are actuable between an extended position and a retracted position. For example, the connector may include an inner housing assembly having optical fibers and an outer housing positioned over the inner housing assembly. The outer housing is shaped to be removable from the inner housing assembly, which has a movable pin clamp mechanically coupled to alignment pins for aligning the connector with another connector. The pin clamp may be slid from a first position (corresponding to a male gender) to a second position (corresponding to a female gender). Separately or in combination with changing gender, the polarity of a communication connector may be changed due to its inclusion of an asymmetric polarity-changing feature that is actuable by an installer to change a polarity of the communication connector. Such a feature may actuated by being moved from a first position to a second position relative to the communication connector.

A fiber optic connector including a connector body and a cable, the cable including optical fibers and a non-circular jacket. The fiber optic connector additionally including a resilient jacket, the resilient jacket is rotatable relative to the non-circular jacket. The resilient jacket is enabled to rotate by an insert which includes an outer profile which engages with an inner profile of the resilient jacket. The insert includes an inner profile which prevents relative rotation between the insert and the non-circular jacket.

An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, ferrule springs for urging the optical ferrules towards a mating connection, and a back body for supporting the ferrule springs. A removable inner front body for polarity change is disclosed. A multi-purpose rotatable boot assembly for polarity change is disclosed. The multi-purpose boot assembly can be pushed and pulled to insert and remove the micro connector from an adapter receptacle.

A fiber optic and electrical connection system includes a fiber optic cable, a ruggedized fiber optic connector, a ruggedized fiber optic adapter, and a fiber optic enclosure. The cable includes one or more electrically conducting strength members. The connector, the adapter, and the enclosure each have one or more electrical conductors. The cable is terminated by the connector with the conductors of the connector in electrical communication with the strength members. The conductors of the connector electrically contact the conductors of the adapter when the connector and the adapter are mechanically connected. And, the conductors of the adapter electrically contact the conductors of the enclosure when the adapter is mounted on the enclosure.

An optical fiber connector sub-assembly for an optical fiber connector includes a ferrule configured to hold an optical fiber therein along an axis of the ferrule and a ferrule holder configured to hold the ferrule. The ferrule has an end face at which the optical fiber is terminated, and the ferrule holder includes a base in which the ferrule is configured to be seated. The sub-assembly includes a ferrule basket including an inner sleeve slidably coupled with an outer sleeve and configured to isolate a front end of the connector from a rear end of the connector such that the ferrule is isolated from movement of the rear end of the connector. The ferrule basket is configured to receive the ferrule holder therein.

The present disclosure relates to a fiber optic connector for use with a fiber optic adapter. The fiber optic connector includes a connector housing having an end defining a plug portion. A ferrule assembly is mounted at least partially within the connector housing. The ferrule assembly includes a ferrule located at the plug portion of the connector housing. A sealing member is mounted about an exterior of the connector housing for providing a seal between the connector housing and the adapter. The fiber optic connector further includes first and second separate retaining mechanism for retaining the fiber optic connector within the fiber optic adapter.

A LC type connector assembly with a push/pull cable boot integrally formed with a protrusion that accepts an adapter release for releasing a fiber optic connector from an adapter port.
