A fiber optic cable includes a tube, a stack of fiber optic ribbons twisting along a lengthwise axis through the tube, a support, and water-blocking tape positioned at least partially around the stack, between the stack and the tube. The support and water-blocking tape provide an elevated portion of the water-blocking tape that is raised. As the stack twists along the lengthwise axis of the tube, corners of the stack interface with the elevated portion to provide intermittent frictional coupling between the stack and the tube.

A fiber optic ribbon cable includes a jacket of the cable, the jacket having a cavity defined therein, an optical element including an optical fiber and extending within the cavity of the jacket, and a dry water-blocking element extending along the optical element within the cavity. The dry water-blocking element is wrapped around the optical element with at least a portion of the dry water-blocking element disposed between another portion of the dry water-blocking element and the optical element, thereby defining an overlapping portion of the dry water-blocking element. The optical element interfaces with the overlapping portion to provide direct or indirect coupling between the optical element and the jacket.

A fiber optic cable includes a tube, a stack of fiber optic ribbons twisting along a lengthwise axis through the tube, and water-blocking tape positioned at least partially around the stack, between the stack and the tube. The water-blocking tape is folded such that an elevated portion of the water-blocking tape is raised. As the stack twists along the lengthwise axis of the tube, corners of the stack interface with the elevated portion to provide intermittent frictional coupling between the stack and the tube.

An optical splitter adjacent a downstream end of a fiber optic cable is operable for supplying an optical signal to at least one optical fiber from the downstream end of the fiber. A preterminated fiber optic distribution cable includes a first access location having an optical fiber termination fed from an upstream end of the cable and a second access location having an optical fiber termination fed from a downstream end of the cable, wherein the cable includes an upstream optical splitter for feeding a first set of optical fibers and a downstream optical splitter for back-feeding a second set of optical fibers. A fiber optic cable comprising a first set of optical fibers that are terminated and fed from an upstream end of the fiber optic cable and a second set of optical fibers that are terminated and fed from a downstream end of the fiber optic cable.

Preterminated fiber optic cable including downstream splitter

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.

A fiber optic cable is provided that includes a plurality of lengthwise extending, non-jacketed bundles of optical fibers and a cable jacket surrounding the bundles of optical fibers. Each bundle of optical fibers may include a binder, such as a binder thread, for maintaining the integrity of the bundle. The binder may include, for example, a binder thread formed of an air entangled, textured, continuous multi-filament thread. The fiber optic cable may also include a separation element for preventing adhesion between the bundles of optical fibers and the cable jacket without having to separately jacket each bundle of optical fibers.
