International Classification:

G02B 644

US Classification:

385114, 385109, 385111

Abstract:

A fiber optic cable including at least one tube assembly therein. The tube assembly includes an optical fiber ribbon stack in a tube. The optical fiber ribbon stack comprises optical fiber ribbons arranged at least partially in a gradually decreasing optical fiber count profile. A diagonal free space of the tube assembly being about 0. 5 mm to about 5 mm. The diagonal free space is defined as the tube inner diameter minus the maximum diagonal length of the ribbon stack. The maximum diagonal length of the ribbon stack being the greater of either a diagonal measurement across lateral subgroups of the ribbon stack or a diagonal measurement across a major dimension of a medial subgroup of the ribbon stack.

International Classification:

G02B 644

US Classification:

385109, 385100, 385102, 385106

Abstract:

A fiber optic cable ( ) having a cable core ( ) includes fiber optic cable components in the form of buffer tubes ( ), a binder ( ), and strength members ( ). Cable core ( ) includes a series of stripes ( ) that comprise a mixture of adhesive and water absorbent substances. The water absorbent substance of stripes ( ) is operative to swell and thereby block the flow of water in cable ( ). Stripes ( ) are made by the sequential coating of the adhesive and the water absorbent substances onto the cable whereby the water absorbent substance is propelled into interstices between the cable components. FIGS. and.

International Classification:

G02B 644

US Classification:

385113, 385114

Abstract:

A fiber optic cable having strength assemblies ( ) adjacent a tube having at least one optical fiber therein, at least one of the strength assemblies including a strength member for imparting crush resistance to the cable. The strength member is generally coupled to a first jacket, and may be surrounded by a single jacket, or by an armor tape and a second jacket. The strength member may be disposed in a recess of the tube. When crush loads are applied to the fiber optic cable, the stresses created in the cable are advantageously distributed by strength assemblies ( ) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. The arrangement of the cable components and strength assemblies ( ) inhibits slippage and/or warping of the components under stress, and thereby evenly distributes the stress for preventing crush induced attenuation in the optical fibers.

Assignee:

Corning Cable Systems LLC - Hickory NC

International Classification:

G02B 644

US Classification:

385114, 385106, 385112

Abstract:

A fiber optic cable includes a buffer tube, a plurality of ribbons of optical fibers extending through the buffer tube and a grease layer disposed between at least one pair of adjacent ribbons. The grease layer includes a base component and a plurality of agglomerates formed filler particles, such as silica particles. The major dimension of the majority of the agglomerates is advantageously less than 100 microns in order to reduce microbending of the optical fibers and the resulting attenuation of the signals propagating along the optical fibers. The fiber optic cable can also include a filling compound that is disposed within the buffer tube and surrounds the optical fibers and that is also formed of a base component and a plurality of agglomerates, the majority of which similarly have a major dimension of less than 100 microns.

US Classification:

385114, 385109, 385110, 385111, 385112

Abstract:

A fiber optic cable ( ) having a tube assembly ( ) therein. Tube assembly ( ) includes an optical fiber group ( ) in a tube ( ). Optical fiber group ( ) comprises a medial optical fiber subgroup ( ) and lateral optical fiber subgroups ( ) adjacent thereto. Subgroups ( ) define a step-like profile for maximizing optical fiber packing density of tube assembly ( ) and/or defining a high fiber count cable ( ). In exemplary embodiments, a diagonal free space is defined as the tube inner diameter minus the diagonal length of the cross-section of the profile of the optical fiber ribbon stack, the diagonal free space being about 2 mm to about 5 mm. In a multi-tube embodiment, diagonal free space can be about 0. 5 mm to about 2 mm. In other embodiments, corner fibers can have a delta optical attenuation of less than about 0.

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.
