A fiber optic cable assembly having a reduced cross-dimensional width includes a fiber optic cable carrying a plurality of optical fibers and having a furcation formed at an end thereof. The furcation includes a furcation housing and a plurality of furcation tubes extending from the furcation housing. Each of the plurality of furcation tubes is configured to receive a number of the plurality of optical fibers. The furcation further includes at least one connection interface terminating the optical fibers received in each of the plurality of furcation tubes. At least one of the furcation tubes has a diameter substantially equal to a theoretical minimum diameter corresponding to the number and size of the optical fibers received therein, and may be formed from a heat shrink material. A method of making such a fiber optic cable assembly is also disclosed.

An optical interconnect system for installing fiber optic cables in an equipment rack having an equipment patch panel with a plurality of coupling port locations is disclosed. The optical interconnect system includes a plurality of cable harnesses configured for installation in the equipment rack and at least one installation tray having a plurality of coupling locations. The plurality of coupling locations receives a connector from the plurality of cable harnesses. The plurality of coupling locations on the installation tray has an arrangement that corresponds to the plurality of port locations on the at least one equipment patch panel, thereby allowing a technician to visually realize that a patching error has occurred during the installation. A method of installing fiber optic cables in an equipment rack using the optical interconnect system is also disclosed.

Disclosed herein are preconnectorized cable assemblies and methods of making using a pull string. One embodiment of the disclosure relates to a method of manufacturing a distribution cable assembly using a pull string fed through a jacket of a distribution cable. Subunit cables are attached to the pull string through openings in the jacket of the distribution cable, and then pulled, via the pull string, through the jacket until drawn through a distribution end opening of the jacket. Another embodiment relates to a distribution cable assembly including junction shells covering side openings in the jacket. The junction shell includes a first half shell attached to a second half shell by a fastener. The first half shell includes stops proximate ends of a side opening to fix the junction shell along an axis of the jacket.

A bundled cable assembly comprises groups of jumpers arranged to define a main section and terminal sections that each extend from the main section. The main section includes a plurality of tap locations at spaced apart locations along a length of the main section. At least some of the jumpers are bundled together in the main section between the tap locations. The terminal sections each extend from one of the tap locations. Each of the jumpers includes a first jumper end in one of the terminal sections and a second jumper end in another of the terminal sections. The groups of jumpers are arranged such that each of the terminal sections comprises the first jumper ends the jumpers from a respective group of the groups of jumpers and at least one second jumper end from each of the other groups of jumpers.

Bundled cable assembly

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.

Fiber optic cable assembly with pulling grip assembly

A fiber optic cable assembly comprises: a cable jacket; 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 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 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. The pulling grip assembly may include one or more air intake devices (e.g., cap or diaphragm) to harness energy from pressurized air used in a jetting process and thereby make it easier to pull the cable assembly through ducts.
