Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a subunit having a first interior surface and a first exterior surface. The first interior surface defines a central bore along a longitudinal axis of the optical fiber cable. At least one optical fiber is disposed within the central bore of the subunit, and a plurality of strengthening yarns is disposed around the subunit. A cable sheath disposed around the plurality of strengthening yarns. The cable sheath has a second interior surface and a second exterior surface. The second exterior surface defines an outermost surface of the optical fiber cable. The cable sheath 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.
