A fiber optic cable assembly comprises: a cable jacket; distinct groups of optical fibers carried within the cable jacket and extending beyond a first end of the cable jacket; a furcation body positioned on the first end of the cable jacket such that the distinct groups of optical fibers extend beyond the furcation body; and a pulling grip assembly having a proximal end selectively secured to the furcation body, a distal end opposite the proximal end, and an interior between the proximal end and the distal end that contains fiber end sections. The interior of the pulling grip assembly is sealed off from an exterior of the cable assembly to provide sealed protection for the fiber end sections over an ambient temperate range of at least between −20 to 50° C. while applying a tensile load of at least 300 lbs to the distal end of the pulling grip assembly.

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 method of furcating a fiber optic cable is disclosed. The method includes positioning an inlet fanout tube and a furcation housing spaced from an end of the cable, removing a protective jacket from the cable to define an exposed portion of a plurality of cable optical fibers, providing a plurality of pre-manufactured connector assemblies that each have an optical connector, splicing the cable optical fibers to a respective one of the connector assemblies to define a splicing region; and repositioning the furcation housing and the inlet fanout tube so that the splicing region is positioned within the furcation housing and the inlet fanout tube covers a section of the exposed portion of the plurality of cable optical fibers. Fiber optic cable assemblies formed by the method are also disclosed.

An optical fiber cable including an optical fiber ribbon in a pipe, wherein the ribbon includes at least two optical fibers arranged side by side, and wherein at least two of the optical fibers are bonded intermittently along a length of the fibers.

The present disclosure provides a flooding composition. In an embodiment, the flooding composition includes in weight percent (wt %) based on the weight of the composition (A) from 10 wt % to 45 wt % of a silane-grafted polyolefin (Si-g-PO). The flooding composition also includes (B) from 5 wt % to 60 wt % of a polyα-olefin oil (PAO oil), (C) from 15 wt % to 90 wt % of a polysiloxane, and (D) from 0.05 wt % to 0.2 wt % of a catalyst.

An optical fiber cable connection structure includes: optical fibers divided into a first bundle and a second bundle in a middle portion of an optical fiber cable in a longitudinal direction of the optical fiber cable; a first fixing portion that integrally fixes the optical fibers of the first bundle in the middle portion; a second fixing portion that integrally fixes the optical fibers of the second bundle in the middle portion; and an optical path that is disposed between the first bundle and the second bundle, holds a space between the first bundle and the second bundle in the longitudinal direction, and optically connects the divided optical fibers to each other.

A cable assembly including a tracer conduit and one or more data transmission conduits. Physically separable proximal and/or distal portions of the data transmission conduit(s) and the tracer conduit are held together by a sleeve. In some examples the sleeve is axially and radially expandable and collapsible multiple times. In some examples, the tracer conduit transmits a visible laser light signal that can be observed after it radially diffuses through the sleeve.

An optical-fiber ribbon having excellent flexibility, strength, and robustness includes optical fibers having a sacrificial, outer release layer that facilitates separation of an optical fiber from the optical-fiber ribbon without damaging the optical fiber's glass core, glass cladding, primary coating, secondary coating, and ink layer, if present.

An optical cable is provided. The optical cable includes an outer cable body jacket and a plurality of optical fiber subunits. The optical fibers within each subunit are stranded relative to each other and are located within a thin subunit jacket. A plurality of unstranded optical fiber subunits are located within the cable jacket.
