An optical fiber structure according to the present application includes a cylindrical resin body, and a plurality of circumferential arrays of optical fiber bare wires disposed within the resin body and extending along a longitudinal direction of the resin body. The resin body includes a linear slit provided at a location intermediate the length of the resin body. The linear slit extends from an outer surface to an inner bore of the resin body and extending substantially parallel to the bare wires.

The present disclosure relates to a cable sleeving tool for applying a split-sleeve over a cable structure. The cable sleeving tool includes an inner guide member defining an inner passage for receiving a cable structure desired to be sleeved. The inner passage extends along a passage axis between an upstream end of the inner guide member and a downstream end of the inner guide member. The inner guide member also includes an inner surface defining the inner passage and an outer sleeve expansion surface for expanding the split sleeve. The cable sleeving tool also includes an outer guide member that surrounds at least a portion of the inner guide member. The outer guide member includes a sleeve containment surface that opposes the outer sleeve expansion surface. The outer sleeve expansion surface and the sleeve containment surface cooperate to define a sleeve passage having a transverse cross-sectional shape that curves generally about the passage axis.

A method organizes fibers. A plurality of fibers is received into a first assembly. An initial sequence of the plurality of fibers in the first assembly is obtained. A set of key combinations is identified from the initial sequence and a predetermined sequence. A second assembly is slid across the first assembly. The set of key combinations is actuated to move the plurality of fibers from the first assembly to the second assembly and order the plurality of fibers in the second assembly in the predetermined sequence.

Fiber optic cable demarcations inhibiting movements of optical fibers relative to strength members, and related cable assemblies and methods, are disclosed. By bonding optical fibers to strength members with a bonding agent received into at least one cavity, a demarcation may be formed inside the cable jacket at a cable jacket interface. The at least one cavity may be disposed within a cable jacket of a fiber optic cable and at the cable jacket interface. The demarcation may bond at least one optical fiber and at least one strength member together to inhibit longitudinal movement of the at least one optical fiber relative to the at least one strength member. In this manner, the demarcation may inhibit optical fiber movement within the fiber optic connector, which may cause tensile forces and/or buckling of the optical fiber resulting in optical fiber damage and/or optical attenuation.

A telecommunication enclosure includes an environmentally sealed housing having an interior volume. The sealed enclosure includes a housing wall defining an opening that extends from the interior to an exterior of the enclosure, the housing wall defining interior threads within the opening. A port-defining element mounts within the opening, the port-defining element defining exterior threads that are threadingly mated with respect to the interior threads to retain the port-defining element within the opening. The port-defining element defines a connector port for receiving a hardened fiber optic connector.

An optical fiber cable includes: an optical fiber; a sheath that accommodates the optical fiber; a tension member that extends from an end portion of the sheath; a housing disposed at an end portion of the tension member; and an anchor portion disposed on the tension member. The anchor portion increases a projected area of the tension member when viewed from a longitudinal direction of the optical fiber cable, the anchor portion is inside the housing, and the housing is filled with a filler that fixes the anchor potion to the housing.

An intermittent tape core wire (140) of an optical fiber cable is assembled into a cable core so that in a k core wire, an l core wire, and an m core wire composed of a multi-core optical fibers continuously adjacent in the width direction of the intermittent tape core wire (140), a difference θ between a core wire twisting direction D2.sub.km of the k core wire at a bonding portion (142) connecting the k core wire and the l core wire and a core wire twisting direction D2.sub.kl of the k core wire at a bonding portion (142) connecting the k core wire and the m core wire is different from when manufactured.

A fiber optic cable assembly comprises: a cable jacket; distinct groups of optical fibers carried within the cable jacket and extending beyond a first end of the cable jacket; a furcation body positioned on the first end of the cable jacket such that the distinct groups of optical fibers have respective fiber end sections extending beyond the furcation body; and a pulling grip assembly protecting the fiber end sections. The pulling grip assembly includes a pulling band releasably secured to the cable jacket by a clamp, and is configured to withstand significant tensile loads despite being easily removable.

Devices such as multiports comprising connection ports with associated securing features and methods for making the same are disclosed. In one embodiment, the device comprises a shell, at least one connection port, at least one securing feature passageway, and at least one securing feature. The at least one connection port is disposed on the multiport with the at least one connection port comprising an optical connector opening extending from an outer surface of the multiport to a cavity of the multiport and defining a connection port passageway. The at least one securing feature is associated with the connection port passageway, and the at least one securing feature is disposed within a portion of the at least one securing feature passageway.

Certain types of fiber termination enclosures include an enclosure and at least one of a plurality of plate module mounting assemblies. Example plate module mounting assemblies include a termination panel plate assembly; a splice tray plate assembly; a cable spool plate assembly; and a drop-in plate assembly. Example cable spool plate assemblies include a cable spool arrangement rotationally coupled to a mounting plate, which fixedly mounts within the enclosure housing. A stand-off mount element may be disposed on the front of the cable spool arrangement to rotate in unison with the cable spool arrangement. The stand-off mount element may include one or more termination adapters.
