US Patent:

6859592, Feb 22, 2005

Filed:

Dec 26, 2001

Appl. No.:

10/035769

Inventors:

David A. Seddon - Hickory NC, US
Michael S. Fedoroff - Saskatoon, SK
William S. Jackman - Hickory NC, US

Assignee:

Corning Cable Systems LLC - Hickory NC

International Classification:

G02B006/44

US Classification:

385111, 385109

Abstract:

A fiber optic cable having optical fibers disposed in buffer tubes, the buffer tubes defining at least two layers generally stranded about a center area of the cable. The buffer tube layers define a relatively inner layer of buffer tubes being closer to the center area, and an outer layer of buffer tubes being relatively further from the center area. The inner and outer buffer tube layers each having a respective helix value, the respective helix values being substantially the same. Alternatively, the respective helix values can be substantially non-equal. In addition, fiber optic cable systems including balanced helix factors have optical connections between layers of buffer tubes of the respective cables.

William S. Jackman - Hickory NC, US

Assignee:

Corning Cable Systems LLC - Hickory NC

International Classification:

G02B006/44

US Classification:

385113

Abstract:

A fiber optic cable includes at least one optical waveguide, at least one strength member, and a jacket. The at least one strength member is a material having an average residual angle in the range of about 30 degrees to about 65 degrees during a bending test using a mandrel having a wire ratio (D/d) of about 200. The strength member is suitable, if necessary, for self-attaching to studs, hooks, or the like by bending it therearound and is also suitable for hardware such as P-clamps or other grips. In other embodiments, strength member is annealed to relieve work hardening. Preferred embodiments use a steel strength member with a carbon content between about 0. 30 percent to about 0. 75 percent. Additionally, a coating may be applied to the strength member for environmental/corrosion protection or conductivity.

International Classification:

G02B006/44

US Classification:

385100, 385102

Abstract:

An optical tube assembly and methods of manufacturing the same include a tube, at least one optical waveguide, and a dry insert. In one embodiment, the dry insert generally surrounds the at least one optical waveguide and forms a core that is disposed within the tube. In one embodiment, the dry insert is compressed at least about 10 percent for coupling the at least optical waveguide to the interior surface of the tube.

Assignee:

Corning Cable Systems LLC - Hickory NC

International Classification:

G02B 6/44

US Classification:

385113, 385103

Abstract:

A figure-eight fiber optic drop cable includes a messenger section and a carrier section connected by a web. The carrier section has at least one optical waveguide and at least one roving. In one embodiment, the carrier section has an average shrinkage of about 0. 5% or less when separated from the messenger section during an average shrinkage test. Also the carrier section of the figure-eight fiber optic drop cable can have an average coefficient of thermal expansion (CTE) section after being separated from the messenger section of about 5. 0×10%/ C. or less for preserving optical performance. Furthermore, a maximum delta attenuation of the at least one optical waveguide during thermal cycling may be about 0. 3 dB/20 meters or less at a reference wavelength of about 1550 nm at a temperature of about −40 C. Other cable configurations are also possible with the invention.

Assignee:

Corning Cable Systems LLC - Hickory NC

International Classification:

G02B 6/44

US Classification:

385102, 385113

Abstract:

A fiber optic drop cable is disclosed that includes at least one optical waveguide disposed within a tube, a first and second strength assembly, and a cable jacket. Each strength assembly includes a strength component and a plurality of strength members, wherein the respective plurality of strength members are radially disposed about at least half of the circumference of the respective strength component. In one embodiment, the first and second strength assemblies are generally disposed on opposite sides of the tube.

US Classification:

385113, 385103, 385100

Abstract:

A fiber optic drop cable including at least one optical waveguide, at least one roving, and a cable jacket. In one embodiment, the at least one roving includes a resin matrix having a water-based acrylic composition that includes an ethylene-acrylic acid and a water-swellable component. The resin matrix has a percent by weight of about 10 percent or less of the flexible roving so that the at least of one roving is at least partially bonded with the cable jacket, thereby inhibiting buckling of the cable jacket. In another embodiment, a plurality of rovings are arranged in clusters in the cable for influencing the bonding between the rovings and cable jacket. Also, disclosed is a protective casing for protecting and routing optical fibers along with preconnectorized cable assemblies.
