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 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.
