Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable jacket having a first inner surface and a first outer surface. The first inner surface defines a central bore along a longitudinal axis of the optical fiber cable. The optical fiber cable also includes optical fibers disposed within the central bore and a buffer tube surrounding the optical fibers. The buffer tube has a second inner surface and a second outer surface. The optical fiber cable also includes an armor layer disposed between the first inner surface of the cable jacket and the second outer surface of the buffer tube and a water-blocking adhesive disposed between the armor layer and the first outer surface of the buffer tube. The water-blocking adhesive extends along the longitudinal axis of the optical fiber cable and around a circumference of the buffer tube.

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.

An optical cable and method for forming an optical cable is provided. The cable includes a cable jacket including an inner surface defining a channel and an outer surface and also includes a plurality of optical fibers located within the channel. The cable includes a seam within the cable jacket that couples together opposing longitudinal edges of a wrapped thermoplastic sheet which forms the cable jacket and maintains the cable jacket in the wrapped configuration around the plurality of optical fibers. The method includes forming an outer cable jacket by wrapping a sheet of thermoplastic material around a plurality of optical core elements. The method includes melting together portions of thermoplastic material of opposing longitudinal edges of the wrapped sheet such that a seam is formed holding the sheet of thermoplastic material in the wrapped configuration around the core elements.

Laser welding of cable jacket

An optical fiber ribbon and a related cable are provided. The ribbon includes a first group of at least one optical fiber and a second group of at least two optical fibers coupled together. The ribbon includes a first hinge coupling the first group to the second group. The hinge allows movement of the first group and the second group of optical fibers relative to each other such that the ribbon is moveable between an aligned position and a collapsed position. The number of optical fibers in the first group is less than the number of optical fibers in second group.

An optical cable is provided. The optical cable includes a tubular, elongate body having an inner surface defining a cavity extending between first and second ends of the elongate body and an optical transmission element located with the cavity. The optical cable includes a coupling or bonding structure non-permanently and non-rigidly joining the outer surface of the optical transmission element to the elongate body at a plurality of periodic contact zones such that relative movement between the optical transmission element and the elongate body is resisted.

Optical fiber cable with internal periodic coupling structure

An optical communication cable and related method is provided. The cable includes a cable body and a plurality of optical transmission elements surrounded by the cable body. The cable includes a reinforcement layer surrounding the plurality of optical transmission elements and located between the cable body and the plurality of optical transmission elements. The reinforcement layer includes an outer surface and a channel defined in the outer surface that extends in the longitudinal direction along at least a portion of the length of the cable. The cable includes an elongate strength element extending in the longitudinal direction within the channel.

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 fire resistant optical communication cable is provided. The fire-resistant optical communication cable includes an extruded cable body including an inner surface defining a passage in the cable body and an outer surface. The fire-resistant optical communication cable includes a plurality of elongate optical transmission elements located within the passage of the cable body. The fire-resistant optical communication cable includes a layer of intumescent particles embedded in the material of the cable body forming an intumescent layer within the cable body. The cable may include one or more elements having flame resistant coatings that, upon exposure to heat, form a ceramic layer increasing the combustion time of the coated element.

A drop cable includes a jacket, first and second support members, and at least one optical fiber. The jacket has a oval-shaped cavity defined therein, where the minor dimension of the cavity is as small as about 0.25 mm and wherein the major dimension of the cavity is in a range of 0.25 mm to 10 mm. The first and second support members are arranged on opposing sides of the cavity and run generally longitudinally. The optical fiber is within the cavity and has a length greater than a length of the drop cable. Further, the optical fiber is in a substantially serpentine configuration in the cavity, where the serpentine configuration is substantially along a plane defined by a major axis of the oval-shape of the cavity.

A fiber optic assembly includes a buffer tube forming an elongate passage and a plurality of optical fibers positioned therein. The buffer tube includes at least one layer of a composite material that includes a base material and a filler material blended therein. Particles of the filler material have an acicular structure, having a longest dimension that is on average at least ten times a narrowest dimension of the particles. Further the buffer tube has kink resistance.

Fiber optic assembly for optical cable

Disclosed are fiber optic assemblies having at least one optical fiber and a water-swellable powder within a tube and/or cavity and methods for making the same. Fiber optic assemblies of the present invention use relatively low-levels of water-swellable powder while still effectively blocking the migration of tap water and/or saline solutions of 3% by weight along the tube and/or cavity. Furthermore, cleaning of the optical fibers is not necessary before connectorization like with conventional fiber optic cables that use a gel or grease. Generally speaking, at least some of the water-swellable powder is transferred to the inside surface of the tube, cavity, optical fiber or the like; rather, than being a loose powder that is able to migrate within the tube or cavity. Moreover, the existence of water-swellable powder within the fiber optic assembly or cable is nearly transparent to the craft since relatively low-levels are possible.

A plurality of fiber optic cables are manufactured as an assembly of fiber optic cables that are later separated into independent fiber optic cables. A method of manufacturing the fiber optic cable assembly is also described. A jacketing cover is extruded over components of the fiber optic cables with a portion connecting the fiber optic cables, and the fiber optic cables can separated from each other by tearing, cutting, or removing a filling element between the fiber optic cables.
