Corning Cable Systems LLC - Hickory NC

International Classification:

G02B 644

US Classification:

385101, 385102, 385104, 385109, 385111

Abstract:

A fiber optic cable including a cable core having at least one optical fiber and a ripcord. In one embodiment, the ripcord is a conductive material operative, upon application of a sufficient pulling force, to rip at least one cable component for facilitating access to said at least one optical fiber. In other embodiments, the ripcord is formed from a semi-conductive material, the ripcord is removably attached to at least one cable component, and/or the ripcord has an excess length.

Assignee:

Corning Cable Systems LLC - Hickory NC

International Classification:

G02B 6/44

US Classification:

385107, 385102

Abstract:

A fiber optic cable including at least one optical fiber and at least one dry insert disposed within a cavity of a cable jacket and methods for manufacturing the same are disclosed. The dry insert has a first thickness and a second thickness located at different longitudinal locations along the dry insert, where the first thickness is greater than the second thickness. The region of the cable having the first thickness of the dry insert provides and/or increases the coupling level of the at least one optical fiber to the cable jacket. In further embodiments, the optical fiber(s) have a predetermined level of coupling to the cable jacket that is about 0. 1625 Newtons or more per optical fiber for a thirty meter length of fiber optic cable.

US Classification:

385100, 385102, 385106, 385115, 264 129

Abstract:

A fiber optic cable including at least one optical fiber disposed within a cavity of a cable jacket and methods for manufacturing the same are disclosed. The cavity has a first cavity cross-sectional area and a second cavity cross-sectional area located at different longitudinal locations along the cable, where the first cavity cross-sectional area is greater than the second cavity cross-sectional area. The region of the second cavity cross-sectional area of the cable provides and/or increases the coupling level of the at least one optical fiber to the cable jacket. In further embodiments, the fiber optic cable is a dry cable having one or more dry insert within the cavity for cushioning and/or optionally providing water-blocking for the cable.

International Classification:

G02B 6/38

Abstract:

An optical cable assembly is provided. The cable assembly includes a plurality of subunits surrounded by an outer cable jacket, a furcation unit and optical connectors coupled to the end of each of the subunits. Each of the subunits includes an inner jacket, a plurality of optical fibers; and a tensile strength element. The first tensile strength element and the inner jackets of each subunits are coupled to the furcation unit, and the optical fibers and tensile strength elements of each subunit extend through the furcation unit without being coupled to the furcation unit. The subunit tensile strength element and optical fibers of each subunit are balanced such that both experience axial loading applied to the assembly and, under various loading conditions, the compression of the subunits is controlled and/or the axial loading of the optical fibers is limited to allow proper function of the optical connector.
