Abstract: A loop back connector and methods for testing lines in a fiber optic network are disclosed. The loop back connector includes a ferrule having an interface side constructed for optical connection to a multifiber optical cable. The loop back connector also includes first and second optical loop back paths, each having first and second terminal ends positioned at the interface side. The terminal ends of each loop back path are adapted to be aligned to fibers in the multifiber optical cable. The method includes injecting a signal on a first optical path at a first location, looping back the signal at a second location onto a second optical path, and receiving the signal on the second optical path at the first location.

Abstract: The present disclosure relates to a fan-out arrangement. The fan-out arrangement may include a main cable that includes a jacket containing a plurality of optical fibers and a plurality of breakout cables that receive the optical fibers of the main cable. The fan-out arrangement may include a fan-out device for transitioning the optical fibers from the main cable to the breakout cable. The fan-out device may include a fan-out housing that includes oppositely positioned first and second housing ends. The fan-out device may also include a fiber transition insert that mounts within the fan-out housing.

Abstract: A multi-fiber cable assembly includes an optical connector and a cable. The optical connector includes a connector body; an optical ferrule body, and alignment elements. The optical ferrule body has an end face defining a plurality of alignment openings arranged in rows and has a plurality of buckling chambers. Each buckling chamber is aligned with one of the rows of the alignment openings. The optical fibers of the cable have bare portions secured at a first end of the optical ferrule body using rigid epoxy. Each of the optical fibers is routed through one of the buckling chambers to one of the alignment holes.

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: 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: Optical connector arrangements terminate at least seventy-two optical fibers. The optical connector arrangements include multiple optical ferrules that each terminates multiple optical fibers. Some example optical connectors can terminate about 144 optical fibers. Each optical connector includes a fiber take-up arrangement and a flange extending outwardly from a connector housing arrangement. The fiber take-up arrangement manages excess length of the optical fibers. A threadable coupling nut can be disposed on the connector housing arrangement to engage the outwardly extending flange. Certain types of optical connector arrangements include furcation cables spacing the connector housing arrangement form the fiber take-up arrangement.
