description Embodiments of the disclosure relate to an optical fiber cable (10) . The optical fiber cable (10) includes a subunit (14) having a first interior surface (16) and a first exterior surface (18) . The first interior surface defines a central bore (20) along a longitudinal axis of the optical fiber cable. At least one optical fiber (12) is disposed within the central bore of the subunit, and a plurality of strengthening yarns (24) is disposed around the subunit (14). A cable sheath (26) disposed around the plurality of strengthening yarns (24). The cable sheath (26) has a second interior surface ( 28) and a second exterior surface. The second exterior surface defines an outermost surface of the optical fiber cable. The cable sheath (26) includes from 55% to 68% by weight of a mineral-based flame retardant additive and from 35% to 45% by weight of a polymer blend. The polymer blend includes a co-polyester or co-polyether and a polyolefin or a polyolefin elastomer.
