The bond between abutting layers is controlled by introducing particulate matter at the interface of the layers.

Methods of controlling bonding and articles formed therefrom

An optical tube assembly having at least one optical waveguide, at least one dry insert, and a tube. In one embodiment, the dry insert has a first layer and a second layer. The first layer is a polyurethane foam and the second layer is a water-swellable layer, wherein the dry insert is disposed within the tube and generally surrounds the at least one optical waveguide.

Optical tube assembly having a dry insert and methods of making the same

Disclosed are tubeless fiber optic cables having strength members, methods of making the cables, and methods for making strength members. Specifically, the concepts of the invention inhibit the distortion and/or influence the cross-sectional shape of the tubeless fiber optic cables due to torsional forces from the strength members. For instance, one tubeless fiber optic cable of the invention uses strength members with a dead-lay construction for inhibiting distortion of the same. Another tubeless fiber optic cable design uses strength members on opposite sides of the cavity where the torsional forces from the strength members are in opposite directions for influencing the cross-sectional shape of the same. Other aspects of the invention are directed to methods for making the tubeless fiber optic cables.

Tubeless fiber optic cables having strength members and methods therefor

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.

Fiber optic cable having a ripcord

A fiber optic cable having at least one interface being formed by a plurality of adjacent support members. Adjacent the interface is at least one retention area having an optical fiber component disposed therein. The retention area is disposed generally longitudinally and non-helically relative to an axis of the cable. The cable can also include a cable jacket substantially surrounding the support members, a cushioning zone adjacent the optical fiber component, a water-blocking component and/or an interfacial layer at least partially disposed between an outer surface of the support members and the cable jacket.

Non-stranded high strength fiber optic cable

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.
