Filed:

Jul 27, 2012

Appl. No.:

13/560409

Inventors:

Bradley Jerome Blazer - Granite Falls NC, US
Andrew Scott Dodd - Hickory NC, US
Dieter Erwin Kundis - Lautertal, DE
Sebastian Olszewski - Lodz, PL

International Classification:

G02B 6/44
G02B 6/04

US Classification:

385102, 4271632

Abstract:

A fiber optic cable includes a subunit and an outer portion. The subunit includes a subunit jacket defining a passageway interior thereto, an optical fiber extending through the passageway, and a first reinforcement material constraining the optical fiber within the subunit jacket such that the optical fiber and the subunit jacket are coupled to one another by way of the first reinforcement material. The outer portion of the fiber optic cable includes an outer jacket defining an outer periphery of the cable and a second reinforcement material between the outer jacket and the subunit jacket. The second reinforcement material includes fiberglass yarn, and hoop stress applied to the fiberglass yarn by the outer jacket constrains the fiberglass yarn such that it is positioned and oriented to provide anti-buckling support to the fiber optic cable and mitigate effects on the optical fiber of jacket shrinkage due to low temperatures.

Appl. No.:

8/122167

Inventors:

Bradley A. Warner - Denver CO
Andrew S. Dodd - Hickory NC

Assignee:

Siecor Corporation - Hickory NC

International Classification:

G02B 644

US Classification:

385100

Abstract:

Disclosed is a dielectric cable having two tubes separated by a web, one tube holding at least one light waveguide therein and the other tube holding a material which creates a magnetic field capable of above ground detection when the cable is buried.

Appl. No.:

7/750415

Inventors:

Christopher K. Eoll - Hickory NC
Andrew S. Dodd - Hickory NC
Richard S. Wagman - Hickory NC

Assignee:

Siecor Corporation - Hickory NC

International Classification:

G02B 644

US Classification:

385114

Abstract:

A light waveguide cable includes a compartment holding at least two side-by-side stacks of light waveguide ribbons. The cable is so dimensioned that the order of the ribbons within any stack, and the relative positions of the stacks with respect to each other within any compartment, do not change under normal cable handling conditions.

Appl. No.:

7/862475

Inventors:

Michael J. Barrett - Hickory NC
Andrew S. Dodd - Hickory NC

Assignee:

Siecor Corporation - Hickory NC

International Classification:

G02B 644

US Classification:

385101

Abstract:

Disclosed is a cable in which one tube holding light waveguides is connected by a plastic web to another tube holding metallic current carrying conductors. When buried in the earth, the cable may be located by means of a magnetic field produced by the current carrying conductors, but the cable retains the advantage of the tube carrying the light waveguides being dielectric.

David Wesley Chiasson - Edmonton, CA
Andrew S. Dodd - Hickory NC, US
David Henry Smith - Hickory NC, US

International Classification:

G02B 6/44

Abstract:

An optical cable includes a cable body having an outer surface and an inner surface defining a lumen. The cable body has a profile feature formed on the outer surface, wherein the profile feature includes a trough that extends longitudinally between a first buttress and a second buttress, the first buttress and the second buttress having a radial height. The trough defines a continuous concave surface between the first buttress and the second buttress that is recessed below the radial height. An ink layer is adhered to the concave surface, wherein the ink layer forms alphanumeric characters that provide information related to the optical cable.

International Classification:

G02B 6/44

Abstract:

An optical cable is provided. The optical cable includes a cable body having an outer surface and an inner surface defining a lumen and one or more optical transmission elements located within the lumen. The optical cable includes a groove array comprising a plurality of grooves located on the outer surface of the cable body. Each groove defines a trough having a lower surface located between peaks on either side of the trough, and the groove array includes an average groove spacing. The optical cable includes an ink layer applied to the cable body at the location of the groove array. The groove array and the ink layer are formed to limit abrasion experienced by the ink layer.

Corning Optical Communications LLC - Hickory NC

International Classification:

B29D 11/00

US Classification:

264 129

Abstract:

A method of manufacturing a fiber optic cable includes manufacturing a subunit and manufacturing an outer portion. Manufacturing the subunit includes extruding a subunit jacket over a first reinforcement material constraining an optical fiber. Manufacturing the outer portion of the fiber optic cable includes extruding an outer jacket over a second reinforcement material between the outer jacket and the subunit jacket. Hoop stress is applied to the second reinforcement material by the outer jacket, which constrains the second reinforcement material such that it is positioned and oriented to provide anti-buckling support to the fiber optic cable and mitigate effects on the optical fiber of jacket shrinkage due to low temperatures.
