A communications cable (20) in which plastic material which is disposed about each transmission medium thereof is characterized by a relatively low dielectric constant. The cable exhibits relatively low flame spread and low smoke generation while maintaining circuit integrity through a fire retardant composition which includes a mixture of an organic resin and first and second inorganic oxide constituents. The first inorganic oxide constituent is characterized by a melting point in the range of about 350°C. The second inorganic oxide constituent comprises a highermelting devitrifying frit which begins to crystallize at about 650°C. Advantageously, when the cable is exposed to high temperatures, the mixture of the first and second inorganic oxide constituents melts and forms a crusty layer which is interposed between the covering plastic material and other components of the cable.
