An optical fiber cable that includes subunits is provided. The cable has an outer jacket having a thickness of at least 2.0 millimeters and that is made from a fire retardant polymer material having a PHRR value of 222 kw/mwhen tested in a cone calorimeter measured according to ASTM E1354 with a heat flux of 50 kW/m. The cable meets the requirement of UL 1666 burn test for riser cables and the requirements of EN 50399 burn test for CPR class Ccables.

Flexible indoor/outdoor high-fiber-count cable

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.

Optical fiber cable with parallel ribbon subunits

An optical communication cable includes a jacket having an interior surface that defines a cable jacket internal cross-sectional area and a plurality of optical fibers, wherein less than 60% of the cable jacket internal cross-sectional area is occupied by the cross-sectional area of the plurality of optical fibers. A scaffolding structure is provided adjacent to and supporting the jacket such that when the jacket is subjected to a burn and melts, the melted jacket material bonds to the scaffolding structure rather than sloughing off.

Structure for flaming droplet suppression in optical fiber cables

Embodiments of an optical fiber cable are provided. The optical fiber cable includes an outer jacket, an inner jacket, a porous insulating layer, and at least one optical fiber. The outer jacket has a first thickness between its inner surface and its outer surface. The inner jacket has a second thickness between its inner surface and its outer surface. The inner jacket is disposed within the outer jacket. The porous insulating layer is disposed between the inner jacket and the outer jacket. The porous insulating layer is configured to reduce the transfer of heat to the inner jacket during combustion of the outer jacket. The optical fiber is disposed within the inner jacket. In the optical fiber cable, the first thickness is less than the second thickness, and each of the outer jacket and the inner jacket include at least one flame retardant additive.

Fire resistant cable having two jackets separated by porous insulating layer

An optical communication cable is provided. The optical communication cable includes a cable jacket and a plurality of optical fiber subunits surrounded by the cable jacket. Each optical fiber subunit includes a subunit jacket and a plurality of optical fibers located within the subunit passage. Each optical fiber includes an outer polymer buffer coating, such as a tight buffer coating. The outer cable jacket and/or the outer polymer buffer coating of the optical fibers is formed from a halogen containing polymer material including a fire retardant material, and the subunit jacket is formed from a polyolefin polymer material including a fire retardant material.

Fire retardant and low-smoke optical communications cable

An optical communication cable bundle is provided. The cable bundle includes a bundle jacket having an inner surface defining a bundle passage and an outer surface defining an exterior surface of the cable bundle, and a plurality of optical fiber subunits located within the bundle passage and surrounded by the bundle jacket, each optical fiber subunit having a subunit jacket defining a subunit passage and a plurality of optical fibers located with the subunit passage. A thickness of the bundle jacket is less than a thickness of each of the subunit jackets and the bundle jacket is extruded tight around the subunit jackets to couple the subunits and the bundle jacket.

Optical fiber bundle

An optical communication cable is provided. The optical communication cable includes an outer cable layer and a plurality of optical fiber bundles surrounded by the outer cable laver. Each optical fiber bundle includes a bundle jacket surrounding a plurality of optical fiber subunits located within the bundle passage. The plurality of optical subunits are wrapped around each other within the bundle passage forming a wrapped pattern. Each optical fiber subunit includes a subunit jacket surrounding a elongate optical fiber located within the subunit passage. The cable jacket, bundle jacket and subunit jacket may be fire resistant, and strength strands of differing lengths may be located in the bundles and the subunits.

Optical fiber cable

Fiber optic bundles include helically stranded subunit cables. The assemblies have small cross sections and low bend radii while maintaining acceptable attenuation losses. Binders can be omitted to improve ease of processing and installation. Helically stranding of the subunit cables allows ease of access to the individual cables during installation.

A rugged optical micromodule cable is provided. The cable includes a composite cable jacket including a first cable jacket layer formed from a first material and a second cable jacket layer formed from a second material. The first cable jacket layer provides at least 10% of the thickness of the cable jacket and the second cable jacket layer provides at least 10% of the thickness of the cable jacket. The first material is different than the second material, and each material provides different physical properties to the cable jacket.
