摘要:
An optical fiber cable includes a jacket and modules including optical fibers. The jacket has an interior that forms an elongate conduit between proximal and distal ends. The modules extend lengthwise through the conduit without being bound together in a pattern of twisting or wound together in a pattern of stranding. Also, the jacket and modules are sized such that free space is provided within the conduit between the modules and the jacket. The jacket is at least ten meters long, and the orientation, alignment, and size of the modules allow individual modules to slide lengthwise relative to one another through the conduit. Pulling one of the modules from the proximal end of the jacket while holding the other modules fixed at the distal end of the jacket draws the one module further into the jacket on the distal end of the jacket.

摘要:
Micromodule subunit cables are constructed to allow for ease of identification between optical fibers in differing groups of optical fibers. In one cable, a first group of fibers is located within a first subunit while a second group of fibers is located within a second subunit, both subunits being enclosed in a cable jacket.
摘要:
A fiber optic cable with first and second cavities accommodating separate groups of fibers. Arranging the optical fibers in separate cavities allows the fibers to be distinguished from one another without requiring secondary marking indicia such as stripes on the fibers. The cable jacket can be extruded such that the cavities are formed integrally in the jacket during extrusion.

摘要:
Optical fibers are lightly tacked together in parallel relation to prevent relative sliding between the fibers along their lengthwise directions, by forming a longitudinally extending frangible web bonded between the fibers. The web in one embodiment is formed by applying a coating of a hardenable composition in a fluid state to the adjacent fibers and then removing the composition from the fibers except on the opposing surfaces of the adjacent fibers, and causing or allowing the composition remaining between the fibers to harden. Alternatively, a coloring compound is coated onto each fiber and the fibers are pressed and held together until the compound solidifies. In yet another embodiment a solid coating of material soluble in a volatile solvent is provided on each fiber, and the coatings are contacted by solvent to render them tacky, the fibers then being pressed and held together until the coatings resolidify.
摘要:
A furcation tube for an optical fiber cable comprising a plurality of channels for receiving a plurality of optical fiber strands that allows for the breakout of multiple fiber groups without the need for marking individual fibers. For example, a 24 fiber cable can be broken out into two, 12-fiber groups within the same furcation tube for connectorization. This improves the sortabilility of the optical fiber strands and eliminates the extra bulk of using multiple furcation tubes. The furcation tube includes strength members disposed therein for strain relief.

摘要:
A fiber optic interconnect cable having at least one optical fiber ribbon surrounded by a cable jacket with substantial hoop strength, the cable jacket having a top wall, a bottom wall, and sidewalls. The sidewalls being thicker than the top and bottom walls. The jacket being formed of a material having a hardness for cable performance characteristics, the hardness being between a Shore A hardness of about 85 and a Shore D hardness of about 70. Other embodiments include a core formed as a generally rod-shaped structure with a plurality of slots formed in an outer surface thereof. The plurality of slots extending generally lengthwise along the core and an outer jacket surrounding the core. At least one interconnect ribbon cable is disposed in at least one of the slots.
