Cables have dielectric armor with an armor profile that resembles conventional metal armored cable. The armor can be formed as a single layer, without requiring an outer jacket layer. The dielectric armor provides additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein. The armored cables recover substantially from deformation caused by crush loads. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space. The assemblies can additionally be lightweight and relatively inexpensive to manufacture.

Armored fiber optic assemblies and methods of forming fiber optic assemblies

A fiber optic cable assembly includes a distribution cable and a tether cable. The distribution cable includes a jacket having a generally flat profile such that the periphery of the distribution cable, when viewed in cross-section, includes two major surfaces of the jacket that are generally flat and are connected by arcuate end surfaces of the jacket. The jacket defines a cavity therein. Further, the distribution cable includes strength members embedded in the jacket and positioned on opposing sides of the cavity. The distribution cable includes a plurality of optical fibers extending through the cavity. The tether cable includes an optical fiber that is fusion spliced to one of the optical fibers of the distribution cable by way of an opening in a side of the jacket of the distribution cable.

Fiber optic cable assembly

A fiber optic cable includes at least one optical fiber, at least one strength member, armor components, and a cable jacket. The cable jacket has a cavity with a generally rectangular cross-section with the armor components disposed on opposite sides of the cavity.

Dry fiber optic cables and assemblies

A fiber optic cable includes a jacket, a pair of strength members, and an optical fiber. The jacket has a cavity, a major dimension and a minor dimension, and a medial portion. The strength members are disposed on opposing sides of the cavity and impart a preferential bend characteristic to the cable. The at least one optical fiber is disposed within the cavity. The jacket includes preferential tear portions disposed between a respective strength member and the medial portion, for separating the strength members from the medial portion.

Fiber optic cables and assemblies

A fiber optic ribbon cable includes a jacket having a cavity and a stack of fiber optic ribbons in the cavity. Each of the fiber optic ribbons includes optical fibers arranged side-by-side with one another and bound to one another with a common matrix in bound sections of the respective fiber optic ribbon. Each fiber optic ribbon additionally has loose sections thereof where the optical fibers of the respective fiber optic ribbon are loose and unbound. The bound sections are spaced apart from one another and separated from one another by the loose sections, while matrix of each of the bound sections contiguously extends across each of the optical fibers of the fiber optic ribbon. Bound sections of adjoining fiber optic ribbons of the stack are at least partially non-overlapping one another as arranged in the stack, which facilitates flexibility and compactness of the stack.

Cables have dielectric armors with armor profiles that provide additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein, while retaining flexibility to aid during installation. The armored cables recover substantially from deformation caused by crush loads.

Cables have armor including a polymer, the armor having an armor profile that resembles conventional metal armored cable. The armor provides additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein. The armored cables recover substantially from deformation caused by crush loads. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space.

Armor, configured for use with a fiber optic assembly, includes a dielectric tube having an armor profile and a length, where the dielectric tube has at least one layer formed from a rigid material. The armor profile is undulating along the length, and the armor profile has a band thickness and a web thickness. The band thickness is between about 0.5 millimeters and about five millimeters. The web thickness is less than the band thickness, and the web thickness is greater than or equal to 0.1 times the band thickness.

Armor for a fiber optic assembly

Armored fiber optic assemblies are disclosed that include a dielectric armor along with methods for manufacturing the same. The dielectric armor has an armor profile, thereby resembling conventional metal armored cable to the craft. The dielectric armor provides additional crush and impact resistance and the like for the optical fibers and/or fiber optic assembly therein. The dielectric armor is advantageous to the craft since it provides the desired mechanical performance without requiring the time and expense of grounding like conventional metal armored cables. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space.
