Fiber optic enclosure assembly
A telecommunications enclosure includes first and second generally aligned cable ports at opposing ends of the enclosure. A cable anchor at each of the first and second cable ports is for anchoring a fiber optic drop cable to the enclosure and to limit axial movement of the cable relative to the enclosure. A blade guide structure is positioned between the first and second cable ports, the blade guide structure configured to abut a portion of the cable extending between the first and second cable ports and defining at least a blade guide surface adapted to guide a cutting blade used for removing a portion of a cable jacket without damaging optical fibers of the cable.
BINDER FILM SYSTEM
A fiber optic cable includes core elements wound in a pattern of stranding, the core elements comprising tubes surrounding optical fibers. The fiber optic cable further includes an binder film surrounding the stranded core elements. The binder film is continuous peripherally around the core elements, forming a continuous closed loop when viewed in cross-section, and continuous lengthwise along a length of the cable that is at least a meter. Further, the binder film is in radial tension and opposes outwardly transverse deflection of the core elements.
Cable assembly with a removable installation device
A cable assembly is described that includes a preterminated optical fiber drop cable having a connector body mounted on a terminal end thereof, and a removable installation device attached to a jacket of the preterminated optical fiber drop cable by an attachment portion, wherein the attachment portion includes a pair of tear tabs that provides tool-less removal of the installation device from the preterminated optical fiber drop cable.
FIBER OPTIC CABLE ASSEMBLY
A cable assembly includes a distribution cable, a tether cable, and a network access point (NAP) assembly having a cavity defined therein. The distribution cable includes optical fibers and the tether cable includes an optical fiber. The optical fiber of the tether cable is tightly constrained within the tether cable and portion thereof extends from the tether cable into the cavity of the NAP assembly and is spliced to a portion of one of the optical fibers of the distribution cable extending into the cavity of the NAP assembly from a side of the distribution cable. The splice is positioned in the cavity. Tight constraint of the optical fiber of the tether cable within the tether cable limits transmission of fiber movement to the portion of the optical fiber of the tether cable extending into the cavity of the NAP assembly, thereby protecting the splice.
SHEATH SPLITTER AND CUTTER
A fiber cable may be neatly and efficiently cut if the razor edge is held in a fixed position while the cable is pulled along a cutting channel. The cable may be first cut to remove the outer layer prior to cutting further layers. One example may have a double cable splitting device with two sets of channels that include razors in each of the channels which locks in to position to secure the cable and razor against the cable during a cutting procedure.
HANDHELD TOOL FOR REMOVING A WIRE FROM WITHIN AN OPTICAL CABLE
Handheld tools are provided for removing a wire from within an optical cable. For example, the handheld tool may be used to remove a copper wire from a fiber optic drop cable in an efficient manner without damaging other components of the fiber optic drop cable. Advantageously, the optical cable may be used immediately after the wire is removed without further steps by the technician, such as re-applying an outer protective sleeve, as is commonly required with known tools.
CABLE SHAVING TOOL
A cable-shaving tool for midspan shaving of a cable jacket includes a housing bottom having a first hinge member along an upper edge, a cavity, and a cable groove extending through a length of the housing bottom. The cable-shaving tool includes a second housing shell having an interior portion having a recess with an upper control surface, an exterior portion, and a second hinge member along a second housing shell edge engageable with the first hinge member. The second housing shell is rotatable about the first hinge member. The cable-shaving tool includes a blade removably securable between a blade holder and a blade support surface on the housing lid, the blade extending within a portion of the recess and a movable cable ramp disposed in the cavity of the bottom housing for urging the cable toward the blade when the second housing shell is in a closed position.

Tight constraint of the optical fiber of the tether cable within the tether cable limits transmission of fiber movement to the portion of the optical fiber of the tether cable extending into the cavity of the NAP assembly, thereby protecting the splice.
OPTICAL CABLE
[Problem] The thickness on a ripcord in a circular optical cable is reduced, to improve workability.
[Solution] An optical cable of the present invention includes: an optical fiber unit including optical fibers; a sheath, having a circular external form, configured to house the optical fiber unit in a housing portion; and two strength members embedded in the sheath; and two rip cords, wherein when a direction of connecting the two strength members sandwiching the housing portion is a first direction and a direction intersecting the first direction is a second direction, in a cross section of the optical cable, a cross-sectional shape of the housing portion has a dimension in the second direction greater than that in the first direction, and the two rip cords is disposed to sandwich the optical fiber unit such that a direction of connecting the two rip cords is in the second direction, in the cross section of the optical cable.
Fiber optic cables with access features and methods of making fiber optic cables
Cables are constructed with extruded discontinuities in the cable jacket that allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of material in the cable jacket.
