Abstract: 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.

Abstract: A fanout tube for a furcation of a fiber optic cable assembly carrying a plurality of optical fibers includes an outer casing defining an outer surface and an inner cavity configured to receive one or more of the optical fibers therethrough. The outer casing includes an outer jacket that defines a passageway and at least one strength member disposed in the passageway. The strength member includes at least one tensile strand and a substrate that at least partially covers the tensile strand. At least a portion of the substrate defines a confronting surface configured to form at least a portion of the inner cavity of the outer casing and be isolated from the tensile strand, and thus inaccessible to optical fibers being inserted through the fanout tube. A method of forming a fiber optic cable assembly having a furcation formed from such fanout tubes is also disclosed.

Abstract: An optical fiber cable that includes subunits is provided. Optical fiber cables are used to transmit data over distance. Generally, large distribution cables that carry a multitude of optical fibers from a hub are sub-divided at network nodes into subunits. To furcate the subunits, the respective jackets of the subunits must balance many different characteristics, including flexibility, temperature tolerance, and safety properties.

Abstract: 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/m2 when tested in a cone calorimeter measured according to ASTM E1354 with a heat flux of 50 kW/m2. The cable meets the requirement of UL 1666 burn test for riser cables and the requirements of EN 50399 burn test for CPR class Cca cables.
