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

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.

An optical fiber comprising: (i) a multi-mode silica based glass core, said core having a 80-300 &#x3bc;m diameter and an index of refraction n; (ii) a cladding surrounding the core, said cladding having a thickness &#x2266;20 &#x3bc;m and index of refraction index of refraction n&#x3c;n, the cladding comprising (a) fluorine doped silica with relative index of refraction delta &#x3c;0, or (b) a polymer with relative index of refraction delta &#x3c;0; (iii) a protective coating, the protective coating having a Young's modulus greater than 700 MPa, a thickness &#x2266;15 &#x3bc;m, and an index of refraction index of refraction n&#x3e;n; and (iv) a permanent buffer.

Buffered large core fiber

Cables have dielectric armor with an armor profile that resembles conventional metal armored cable. 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.

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.
