Abstract: A break-out assembly includes an enclosure defining a first port at the first end to receive an optical cable and a second port at the second end to receive a plurality of break-out cables. Each port leads to the interior of the enclosure. A cable retention region defined within the enclosure at the second end is configured to enable the break-out cables to each secure to the enclosure at one of a plurality of axial locations. Certain types of break-out assemblies include other cable retention regions to axially and/or rotationally secure the optical cable to the enclosure. A splice retention region is disposed within the enclosure between the first port and the second cable retention region. The splice retention region receives optical splices at which optical fibers of the optical cable are spliced to optical fibers of the break-out cables.

Abstract: The present disclosure relates to a telecommunications connection device. The device including a housing, a plurality of single-fiber connectorized pigtails that extend outwardly from the housing and a multi-fiber connectorized pigtail that extends outwardly from the housing. The multi-fiber connectorized pigtail can be optically coupled with the single fiber connectorized pigtails. The device can include optical fibers routed from the multi-fiber connectorized pigtail through the housing to the single-fiber connectorized pigtails. The single-fiber connectorized pigtails can be more flexible than the multi-fiber connectorized pigtail.

Abstract: A fiber optic connector and cable assembly includes a cable with one or more strength members secured to a connector that is connectable to both a hardened and a non-hardened fiber optic adapter. The cable can include multiple cable types with various shapes and strength member configurations. The connector includes a connector housing having a one-piece main body and a cover piece mounted thereon. The one-piece main body defines a plug portion compatible with the adapters. A ferrule assembly is mounted in the plug portion and biased outwardly by a spring. An insert within the connector housing includes a spring stop for holding the spring and a cable retention portion for securing the strength members of the cable. The spring stop and the cable retention portion can be included on a one-piece insert or they can separately be included on separate inserts. The cable retention portion of the insert and the cover piece can take various forms suited for a particular cable of a given fiber optic connector and cable assembly.

Abstract: A fiber optic cable assembly includes a fiber optic cable and a fiber optic connector. The cable includes a jacket having an elongated transverse cross-sectional profile that defines a major axis and a minor axis. Strength components of the cable are anchored to the connector. The fiber optic connector includes a multi-fiber ferrule defining a major axis that is generally perpendicular to the major axis of the jacket and a minor axis that is generally perpendicular to the minor axis of the jacket. Certain types of connectors include a connector body defining a side opening that extends along a length of the connector body; a multi-fiber ferrule configured for lateral insertion into the connector body through the side opening; and a cover that mounts over the side opening after the multi-fiber ferrule has been inserted into the connector body through the side opening.

Abstract: 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.
