A fiber optic cable includes a core assembly including an optical fiber, a polymeric sleeve surrounding the core assembly, water-swellable material integrated with the polymeric sleeve, and a jacket surrounding the polymeric sleeve. The polymeric sleeve is continuous peripherally around the core assembly, forming a continuous closed loop when viewed in cross-section, and continuous lengthwise along a length of the cable.

Fiber optic cable with sleeve

A fiber optic cable includes core elements wound in a pattern of stranding, the core elements comprising tubes surrounding optical fibers. The fiber optic cable further includes an binder film surrounding the stranded core elements. The binder film is continuous peripherally around the core elements, forming a continuous closed loop when viewed in cross-section, and continuous lengthwise along a length of the cable that is at least a meter. Further, the binder film is in radial tension and opposes outwardly transverse deflection of the core elements.

Binder film system

A fiber optic cable includes core elements, a composite film surrounding the core elements, and a jacket surrounding the composite film. The core elements include one or more optical fibers and at least one tube surrounding the one or more optical fibers. The composite film includes a first layer adjoining a second layer, where the composition of the second layer differs from the first. The composite film is relatively thin, having an average thickness over a 10-meter length of the cable that is less than half an average thickness of the jacket over the 10-meter length.

Composite film for a fiber optic cable

Durable optical fiber ribbons are formed by promoting a strong bond between fiber ink layers and ribbon matrix material. During curing of the ink layer desired oxygen levels are maintained in the curing environment of the manufacturing process.

A flame-retardant fiber optic cable includes core elements, a film surrounding the core elements, and a jacket surrounding the film. The core elements include one or more optical fibers and at least one tube surrounding the one or more optical fibers. The material composition of the film differs from the jacket and the film is relatively thin.

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.
