  • Patent number: 8909014
    Abstract: A fiber optic cable includes a cable jacket and a core. The cable jacket is tubular, having exterior and interior surfaces, and is formed mostly from a first polymeric material. The jacket includes access features formed from a second polymeric material at least partially embedded in the first polymeric material and extending lengthwise along the jacket. Two of the access features are spaced apart from one another with a section of the jacket formed from the first polymeric material extending laterally therebetween, such that the section may be peeled apart from the rest of the cable lengthwise along the jacket by separation of the jacket about the access features. The core has an outermost surface and includes optical fibers and a strength member. The outermost surface of the core is at least partially bonded to the interior surface of the jacket, which enhances coupling between the jacket and core.

  • Patent number: 8649644
    Abstract: The bond between an armor and a cable covering jacket is controlled by introducing intervening material at the interface of the layers along selected bond regions. The intervening material can comprise particulate matter or a strip of material introduced at selected locations of the armor perimeter to allow ease of access at the selected regions.

  • Publication number: 20130259434
    Abstract: A fiber optic cable assembly includes a fiber optic cable, a tether, and an overmold. The fiber optic cable includes an optical fiber, a strength member, and a jacket, where the jacket includes an interior portion contacting the strength member and an exterior portion adjoining the interior portion. The interior and exterior portions of the jacket both include polyethylene, and the exterior portion further includes an additive that is not in the interior portion. The tether is coupled to the fiber optic cable at an attachment point. The optical fiber or another optical fiber spliced to the optical fiber, diverges from the fiber optic cable via the tether. The overmold encloses the attachment point and is attached directly to a discrete section of the exterior portion of the jacket proximate to the attachment point. The additive facilitates bonding of the overmold to the discrete section.

  • Patent number: 8463095
    Abstract: Cables have dielectric armor with an armor profile that resembles conventional metal armored cable. The dielectric armor provides additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein. The armored cables recover substantially from deformation caused by crush loads. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space.

  • Patent number: 8428406
    Abstract: Armor, configured for use with a fiber optic assembly, includes a dielectric tube having an armor profile and a length, where the dielectric tube has at least one layer formed from a rigid material. The armor profile is undulating along the length, and the armor profile has a band thickness and a web thickness. The band thickness is between about 0.5 millimeters and about five millimeters. The web thickness is less than the band thickness, and the web thickness is greater than or equal to 0.1 times the band thickness.

  • Patent number: 8218925
    Abstract: Armored fiber optic assemblies are disclosed that include a dielectric armor along with methods for manufacturing the same. The dielectric armor has an armor profile, thereby resembling conventional metal armored cable to the craft. The dielectric armor provides additional crush and impact resistance and the like for the optical fibers and/or fiber optic assembly therein. The dielectric armor is advantageous to the craft since it provides the desired mechanical performance without requiring the time and expense of grounding like conventional metal armored cables. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space.

  • Publication number: 20100278492
    Abstract: Cables have dielectric armor with an armor profile that resembles conventional metal armored cable. The armor can be formed as a single layer, without requiring an outer jacket layer. The dielectric armor provides additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein. The armored cables recover substantially from deformation caused by crush loads. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space. The assemblies can additionally be lightweight and relatively inexpensive to manufacture.
