20140086543 | BINDER FILM FOR A FIBER OPTIC CABLE - A fiber optic cable includes a core and a binder film surrounding the core. The core includes a central strength member and core elements, such as buffer tubes containing optical fibers, where the core elements are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the core elements. The binder film is in radial tension around the core such that the binder film opposes outwardly transverse deflection of the core elements. Further, the binder film loads the core elements normally to the central strength member such that contact between the core elements and central strength member provides coupling therebetween, limiting axial migration of the core elements relative to the central strength member. | 03-27-2014 |
20140369656 | COUPLING SYSTEM FOR A FIBER OPTIC CABLE - A fiber optic cable includes a jacket, an element of the cable interior to the jacket, and first and second powders. The element includes a first surface and a second surface. The cable further includes a third surface interior to the jacket and facing the first surface at a first interface and a fourth surface interior to the jacket and facing the second surface at a second interface. At least one of the third and fourth surfaces is spaced apart from the jacket. The first powder is integrated with at least one of the first and third surfaces at the first interface and the second powder integrated with at least one of the second and fourth surfaces at the second interface. The first interface has greater coupling than the second interface at least in part due to differences in the first and second powders. | 12-18-2014 |
20150043874 | OPTICAL FIBER CABLE WITH ANTI-SPLIT FEATURE - An optical communication cable includes a jacket, optical transmission elements, and armor. The jacket is mostly formed from a first material and includes an elongate member formed from a second material embedded in the first material. The jacket defines a channel in which the optical transmission elements are located. The armor includes a wrapped sheet having a lateral edge and is positioned around the optical transmission elements within the channel. The elongate member has an inner surface aligned with and located exterior to the lateral edge of the armor; and, when viewed in cross-section, the elongate member fully overlays and extends tangentially beyond the lateral edge. Accordingly, the elongate member provides an obstacle in the jacket that limits zippering through the jacket originating from the lateral edge. Further, the elongate member may double as a tear feature for quickly accessing contents of the cable interior to the jacket. | 02-12-2015 |
20150086168 | BINDER FILM FOR A FIBER OPTIC CABLE - A fiber optic cable includes a core and a binder film surrounding the core. The core includes a central strength member and core elements, such as buffer tubes containing optical fibers, where the core elements are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the core elements. The binder film is in radial tension around the core such that the binder film opposes outwardly transverse deflection of the core elements. | 03-26-2015 |
20150110451 | OPTICAL FIBER CABLE WITH REINFORCEMENT - An optical communication cable includes a cable body, a plurality of core elements located within the cable body, a reinforcement layer surrounding the plurality of core elements within the cable body, and a film surrounding the plurality of core elements. At least one of the plurality of core elements includes an elongate optical transmission element. The film provides an inwardly directed force onto the core elements, and a surface of the film is bonded to the reinforcement layer. | 04-23-2015 |
20150153531 | STRETCHABLE FIBER OPTIC CABLE - A fiber optic cable includes a strength member, tubes coupled to the strength member, and optical fibers. The strength member provides tensile and anti-buckling strength. The tubes have a cavity into which the optical fibers are packed. The cable is stretchable in that the optical fibers experience less than 0.5 dB/km of increased average attenuation at 1310 nanometers wavelength when the cable experiences strain of up to 2×10 | 06-04-2015 |
20150177471 | FIBER OPTIC CABLE WITH EXTRUDED TAPE - A fiber optic cable includes a tape comprising a substrate of an extrudable thermoplastic, core items of the fiber optic cable, and a jacket around the tape and core items. The tape includes water-swellable material integrated therewith and the core items include one or more optical fibers. The tape is incorporated with core items such that the water-swellable material of the tape is configured to limit water from flowing lengthwise along the cable through gaps among the core item. | 06-25-2015 |
20150205063 | BINDER FILM FOR A FIBER OPTIC CABLE - A fiber optic cable, or a sub-assembly thereof, includes core elements and a binder film. The core elements are wound in a stranded configuration that includes a pattern of reverse-oscillatory winding. The binder film overlays and surrounds the stranded core elements, and constrains the core elements in the stranded configuration. | 07-23-2015 |
