Abstract: A fiber optic telecommunications device includes a rack for mounting a plurality of chassis, each chassis including a plurality of trays slidably mounted thereon and arranged in a vertically stacked arrangement. Each tray includes fiber optic connection locations and a cable manager coupled to the tray and also coupled to the chassis, the cable manager for routing cables to and from the fiber optic connection locations and defining a plurality of link arms pivotally connected such that the manager retracts and extends with a corresponding movement of the tray, wherein the link arms pivot relative to each other to prevent cables managed therein from being bent in an arc having a radius of curvature less than a predetermined value, each link arm defining a top wall, a bottom wall, and two oppositely positioned sidewalls, each link arm defining an open portion along at least one of the sidewalls and an open portion along the top wall for receiving cables therein, the open portions along the top wall and the at least one of the sidewalls communicating with each other.

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: 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.

Abstract: A cable guide device operates as a cable bend limiting device that is removed once a cable is routed. The device includes a body portion and a guide surface. The body portion is configured to hold the device at a work area. The guide surface provides a surface along which the cable is routed. The guide surface may have a radius of curvature not less than the minimum bend radius of the cable.

Abstract: The present disclosure relates to fiber optic connection systems including fiber optic connector having retractable noses for protecting bare fiber ends of ferrule-less connectors. In certain examples, the retractable noses are used in combination with protective shutters. In other examples, the retractable noses can accommodate multiple optical fibers.

Abstract: Aspects and techniques of the present disclosure relate to fiber optic connectors with features that help eliminate the potential of a capillary effect or epoxy wicking. The fiber optic connector may include an epoxy tube with segments that define a pocket in an area that helps to prevent capillary action between components that are otherwise closely positioned.

Abstract: A fiber optic connector with a hub extension positioned on the hub of the connector. Prior to assembly of the connector with the rear boot, the hub and ferrule assembly can be pushed backward within the front and rear housings to clear an anti-rotation portion of the front housing and turned for tuning. After complete assembly of the rear boot, the hub extension bottoms out against the boot prior to the hub and ferrule assembly disengaging the anti-rotation portion of the front housing, thereby maintaining the tuned position.

Abstract: Fiber optic connectors, connector assemblies, and associated methods having tuning features and aspects. The tuning features/aspects allow for a tuning mechanism of a rear housing to be moved axially between an anti-rotation region and a tuning chamber defined by a front housing. The rear housing is rotationally coupled to a ferrule assembly for tuning an optical fiber terminated at the ferrule assembly.
