    Abstract: Armored fiber optic assemblies and methods are disclosed that include a dielectric armor and at least one bend-resistant multimode optical fiber. 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. The use of at least one bend-resistant multimode optical fiber allows for improved bend performance for the armored fiber optic assemblies, allowing for tighter cable routing as compared to armored fiber optic assemblies having conventional multimode optical fiber.

  • 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: 8412012
    Abstract: An optical fiber cable includes an unbuffered optical fiber, a tensile reinforcement member surrounding the unbuffered optical fiber, and a jacket surrounding the tensile reinforcement member. The jacket is suitable for outside plant environment. A water blocking material is placed between the unbuffered fiber and the jacket. The unbuffered optical fiber comprises an ultra bend-insensitive fiber that meets the requirements of ITU-T G.657.B3 and exhibits an additional loss of less than approximately 0.2 dB/turn when the fiber is wrapped around a 5 mm bend radius mandrel. The optical fiber cable also exhibits an additional loss of less than approximately 0.4 dB/km at 1550 nm when the cable is subjected to ?20° C. outside plant environment.

  • Patent number: 8412011
    Abstract: It is an object of the present invention to provide an optical fiber cable which can reliably prevent increased transmission loss due to damage of the optical fiber as a result of the egg-laying behavior of cicadas. The cable includes at least an optical fiber 1, tension members 6 and a sheath 3. The sheath 3 has a shore D hardness of 55 or more and a minimum distance L from a surface of the optical fiber 1 to an outer surface of the sheath 3 of greater than 0.3 mm. Further, in the cable, the surface of sheath 3 has a coefficient of friction of 0.45 or less and the sheath 3 has a shore D hardness of 57 or more. In addition, the cable is made by using a specific flame retardant composition (P) as the sheath material.

  • Patent number: 8406591
    Abstract: A low cost, high performance, low profile flexible reinforcement member that can be used for both optical and copper communications cable. The reinforcement members made according to the preferred process are more rigid than known reinforcement members, but are less rigid than glass pultruded rods. Communications cables utilizing these members are lightweight and exhibit an improved combination of strength and flexibility compared to traditional communications cables. Further, these communication cables may then be installed into underground ducts using more economical and faster installation techniques.
